Reliability analysis of a utility-scale solar power plant
DOE Green Energy (OSTI)
This paper presents the results of a reliability analysis for a solar central receiver power plant that employs a salt-in-tube receiver. Because reliability data for a number of critical plant components have only recently been collected, this is the first time a credible analysis can be performed. This type of power plant will be built by a consortium of western US utilities led by the Southern California Edison Company. The 10 MW plant is known as Solar Two and is scheduled to be on-line in 1994. It is a prototype which should lead to the construction of 100 MW commercial-scale plants by the year 2000. The availability calculation was performed with the UNIRAM computer code. The analysis predicted a forced outage rate of 5.4% and an overall plant availability, including scheduled outages, of 91%. The code also identified the most important contributors to plant unavailability. Control system failures were identified as the most important cause of forced outages. Receiver problems were rated second with turbine outages third. The overall plant availability of 91% exceeds the goal identified by the US utility study. This paper discuses the availability calculation and presents evidence why the 91% availability is a credible estimate. 16 refs.

Reliability of Electric Utility Distribution Systems: EPRI White Paper
Science Conference Proceedings (OSTI)
This report discusses what is known about electric power distribution system reliability and investigates whether there are generally available methods for performing reliability analysis for distribution systems. The theory of the reliability of general systems is well understood. A fundamental issue is whether an appropriate implementation of the theory exists in a form readily usable by distribution system planners and designers.
An Examination of Temporal Trends in Electricity Reliability Based on Reports from U.S. Electric Utilities
SciTech Connect
Since the 1960s, the U.S. electric power system has experienced a major blackout about once every 10 years. Each has been a vivid reminder of the importance society places on the continuous availability of electricity and has led to calls for changes to enhance reliability. At the root of these calls are judgments about what reliability is worth and how much should be paid to ensure it. In principle, comprehensive information on the actual reliability of the electric power system and on how proposed changes would affect reliability ought to help inform these judgments. Yet, comprehensive, national-scale information on the reliability of the U.S. electric power system is lacking. This report helps to address this information gap by assessing trends in U.S. electricity reliability based on information reported by electric utilities on power interruptions experienced by their customers. Our research augments prior investigations, which focused only on power interruptions originating in the bulk power system, by considering interruptions originating both from the bulk power system and from within local distribution systems. Our research also accounts for differences among utility reliability reporting practices by employing statistical techniques that remove the influence of these differences on the trends that we identify. The research analyzes up to 10 years of electricity reliability information collected from 155 U.S. electric utilities, which together account for roughly 50% of total U.S. electricity sales. The questions analyzed include: 1. Are there trends in reported electricity reliability over time? 2. How are trends in reported electricity reliability affected by the installation or upgrade of an automated outage management system? 3. How are trends in reported electricity reliability affected by the use of IEEE Standard 1366-2003?

Utility-scale grid-tied PV inverter reliability workshop summary report.
A key to the long-term success of the photovoltaic (PV) industry is confidence in the reliability of PV systems. Inverters are the most commonly noted cause of PV system incidents triggered in the field. While not all of these incidents are reliability-related or even necessarily failures, they still result in a loss of generated power. With support from the U.S. Department of Energy's Solar Energy Technologies Program, Sandia National Laboratories organized a Utility-Scale Grid-Tied Inverter Reliability Workshop in Albuquerque, New Mexico, January 27-28, 2011. The workshop addressed the reliability of large (100-kilowatt+) grid-tied inverters and the implications when such inverters fail, evaluated inverter codes and standards, and provided discussion about opportunities to enhance inverter reliability. This report summarizes discussions and presentations from the workshop and identifies opportunities for future efforts.

Estimated Value of Service Reliability for Electric Utility Customers in the United States
Information on the value of reliable electricity service can be used to assess the economic efficiency of investments in generation, transmission and distribution systems, to strategically target investments to customer segments that receive the most benefit from system improvements, and to numerically quantify the risk associated with different operating, planning and investment strategies. This paper summarizes research designed to provide estimates of the value of service reliability for electricity customers in the US. These estimates were obtained by analyzing the results from 28 customer value of service reliability studies conducted by 10 major US electric utilities over the 16 year period from 1989 to 2005. Because these studies used nearly identical interruption cost estimation or willingness-to-pay/accept methods it was possible to integrate their results into a single meta-database describing the value of electric service reliability observed in all of them. Once the datasets from the various studies were combined, a two-part regression model was used to estimate customer damage functions that can be generally applied to calculate customer interruption costs per event by season, time of day, day of week, and geographical regions within the US for industrial, commercial, and residential customers. Estimated interruption costs for different types of customers and of different duration are provided. Finally, additional research and development designed to expand the usefulness of this powerful database and analysis are suggested.

Structural Change and Futures for the Electric Utility Industry
Technological change and evolving customer needs have already combined to precipitate fundamental structural change in several capital-intensive industries, notably the telecommunications, natural gas, and transportation sectors. These forces are now being unleashed in the electric utility sector. This report outlines some common patterns of change across several industries and presents scenarios of structural change for the electric power industry.
Potential Effects of Climate Change on Electric Utilities
In recent years, increasing attention has been focused on the potential for greenhouse gas emissions to modify the global climate system. Significant climate change could affect utility operations and costs through impacts on electricity demand and on generation and delivery systems. Utilities, moreover, may be called upon to take actions to reduce their emissions of CO2, an important greenhouse gas. This report summarizes an assessment of the long-term risks to individual utilities posed by the potentia...
Changes in hydrogen utilization with temperature during direct coal liquefaction
A reliable means of monitoring the major pathways of hydrogen utilization, in contrast to only measuring net hydrogen comsumption, would be very useful for process optimization. The goal of this work was to develop an analytical approach for quantitatively distinguishing hydrogen consumed in hydrogenation from that utilized to stabilize thermolysis fragments. The approach outlined yields a rather detailed description of the net utilization of hydrogen during direct liquefaction, partitioning it into contributions from gas generation, heteroatom removal, hydrogenation, and matrix breakdown. Preliminary results indicate that internal hydrogen reorganization, with little consumption, predominates at low temperatures, with hydrogenation being compensated for by the hydrogen liberated in condensations. As the temperature is increased, bond cleavage reactions and aromatization reactions appear to become more important, and the net hydrogen consumption increases. (3 tables 1 figs., 11 refs.)

Tracking the Reliability of the U.S. Electric Power System: An Assessment of Publicly Available Information Reported to State Public Utility Commissions
Large blackouts, such as the August 14-15, 2003 blackout in the northeasternUnited States and Canada, focus attention on the importance of reliable electric service. As public and private efforts are undertaken to improve reliability and prevent power interruptions, it is appropriate to assess their effectiveness. Measures of reliability, such as the frequency and duration of power interruptions, have been reported by electric utilities to state public utility commissions for many years. This study examines current state and utility practices for collecting and reporting electricity reliability information and discusses challenges that arise in assessing reliability because of differences among these practices. The study is based primarily on reliability information for 2006 reported by 123 utilities to 37 state public utility commissions.

A case study review of technical and technology issues for transition of a utility load management program to provide system reliability resources in restructured electricity markets
Utility load management programs--including direct load control and interruptible load programs--were employed by utilities in the past as system reliability resources. With electricity industry restructuring, the context for these programs has changed; the market that was once controlled by vertically integrated utilities has become competitive, raising the question: can existing load management programs be modified so that they can effectively participate in competitive energy markets? In the short run, modified and/or improved operation of load management programs may be the most effective form of demand-side response available to the electricity system today. However, in light of recent technological advances in metering, communication, and load control, utility load management programs must be carefully reviewed in order to determine appropriate investments to support this transition. This report investigates the feasibility of and options for modifying an existing utility load management system so that it might provide reliability services (i.e. ancillary services) in the competitive markets that have resulted from electricity industry restructuring. The report is a case study of Southern California Edison's (SCE) load management programs. SCE was chosen because it operates one of the largest load management programs in the country and it operates them within a competitive wholesale electricity market. The report describes a wide range of existing and soon-to-be-available communication, control, and metering technologies that could be used to facilitate the evolution of SCE's load management programs and systems to provision of reliability services. The fundamental finding of this report is that, with modifications, SCE's load management infrastructure could be transitioned to provide critical ancillary services in competitive electricity markets, employing currently or soon-to-be available load control technologies.

NGNP Process Heat Utilization: Liquid Metal Phase Change Heat Exchanger
One key long-standing issue that must be overcome to fully realize the successful growth of nuclear power is to determine other benefits of nuclear energy apart from meeting the electricity demands. The Next Generation Nuclear Plant (NGNP) will most likely be producing electricity and heat for the production of hydrogen and/or oil retrieval from oil sands and oil shale to help in our national pursuit of energy independence. For nuclear process heat to be utilized, intermediate heat exchange is required to transfer heat from the NGNP to the hydrogen plant or oil recovery field in the most efficient way possible. Development of nuclear reactor - process heat technology has intensified the interest in liquid metals as heat transfer media because of their ideal transport properties. Liquid metal heat exchangers are not new in practical applications. An important rational for considering liquid metals is the potential convective heat transfer is among the highest known. Thus explains the interest in liquid metals as coolant for intermediate heat exchange from NGNP. For process heat it is desired that, intermediate heat exchangers (IHX) transfer heat from the NGNP in the most efficient way possible. The production of electric power at higher efficiency via the Brayton Cycle, and hydrogen production, requires both heat at higher temperatures and high effectiveness compact heat exchangers to transfer heat to either the power or process cycle. Compact heat exchangers maximize the heat transfer surface area per volume of heat exchanger; this has the benefit of reducing heat exchanger size and heat losses. High temperature IHX design requirements are governed in part by the allowable temperature drop between the outlet and inlet of the NGNP. In order to improve the characteristics of heat transfer, liquid metal phase change heat exchangers may be more effective and efficient. This paper explores the overall heat transfer characteristics and pressure drop of the phase change heat exchanger with Na as the heat exchanger coolant. In order to design a very efficient and effective heat exchanger one must optimize the design such that we have a high heat transfer and a lower pressure drop, but there is always a trade-off between them. Based on NGNP operational parameters, a heat exchanger analysis with the sodium phase change will be presented to show that the heat exchanger has the potential for highly effective heat transfer, within a small volume at reasonable cost.

DOE Patents (OSTI)
A thermal energy transport and storage system is provided which includes an evaporator containing a mixture of a first phase change material and a silica powder, and a condenser containing a second phase change material. The silica powder/PCM mixture absorbs heat energy from a source such as a solar collector such that the phase change material forms a vapor which is transported from the evaporator to the condenser, where the second phase change material melts and stores the heat energy, then releases the energy to an environmental space via a heat exchanger. The vapor is condensed to a liquid which is transported back to the evaporator. The system allows the repeated transfer of thermal energy using the heat of vaporization and condensation of the phase change material.

Electric Power Reliability in Chemical Plants
The quality and reliability of utility-generated electric power is presently receiving a great deal of attention from the chemical and refining industry. What changes have taken place to make electric power reliability a major topic of discussion at plants across the country? Has the quality and reliability of utility-generated power deteriorated over the past five or ten years? Or, has the perception of what constitutes reliable power changed with the advent, installation, and increasing usage of microprocessor-based equipment and controllers? The differing views held by both parties tend to make their relationship adversarial. Both parties have problems with their individuals views and the associated monetary costs, which can be either a loss or a gain. Improved reliability for the chemical plant means less "off spec" product, thereby resulting in more product to sell. Improved reliability for the utility means less customer downtime, thereby resulting in more KWH sales and a higher capacity factor. The biggest limiting factor to solving the actual problems is the dollar cost associated with that solution. Each solution must have a payback period that meets the economic criteria for return on investment for either the industry or the utility.

Power electronics reliability analysis.
This report provides the DOE and industry with a general process for analyzing power electronics reliability. The analysis can help with understanding the main causes of failures, downtime, and cost and how to reduce them. One approach is to collect field maintenance data and use it directly to calculate reliability metrics related to each cause. Another approach is to model the functional structure of the equipment using a fault tree to derive system reliability from component reliability. Analysis of a fictitious device demonstrates the latter process. Optimization can use the resulting baseline model to decide how to improve reliability and/or lower costs. It is recommended that both electric utilities and equipment manufacturers make provisions to collect and share data in order to lay the groundwork for improving reliability into the future. Reliability analysis helps guide reliability improvements in hardware and software technology including condition monitoring and prognostics and health management.

Review of nuclear power plant offsite power source reliability and related recommended changes to the NRC rules and regulations
The NRC has stated its concern about the reliability of the offsite power system as the preferred emergency source and about the possible damage to a pressurized water reactor (PWR) that could result from a rapid decay of power grid frequency. ORNL contracted with NRC to provide technical assistance to establish criteria that can be used to evaluate the offsite power system for the licensing of a nuclear power plant. The results of many of the studies for this contract are recommendations to assess and control the power grid during operation. This is because most of the NRC regulations pertaining to the offsite power system are related to the design of the power grid, and we believe that additional emphasis on monitoring the power grid operation will improve the reliability of the nuclear plant offsite power supply. 46 refs., 10 figs.

Implementation of a Dual Containment/Surveillance System utilizing scene-change detection and radio frequency technology
This paper will examine the implementation of scene-change detection and radio frequency technology within a Dual Containment/Surveillance (C/S) System. Additionally, this paper will examine the human performance factors in the operation of these systems. Currently, Westinghouse Savannah River Company utilizes the Continuous Item Monitoring and Surveillance System (CIMS) in the performance of Dual C/S to monitor special nuclear materials within International Atomic Energy Agency (IAEA) Safeguards and Domestic Safeguards. CIMS is comprised of the Material Monitoring System (MMS) (R), a multi-media electronic surveillance system developed by Sandia National Laboratory which incorporates the use of active seals commonly called Radio Frequency Tamper Indicating Devices (RFTIDs), NT Vision (R) as developed by Los Alamos National Laboratory, a Microsoft Windows NT (R) based operating system providing for domestic scene-change detection and the Digital Multi-Camera Optical Surveillance System (DMOS) (R) which provides scene-change detection for IAEA. Although this paper will focus on the implementation of Dual C/S utilizing the Continuous Item Monitoring and Surveillance System, the necessity for a thorough review of Safeguards and Security requirements with organizations and personnel having minimal to no prior MPC&A training will also be covered. Successful Dual C/S implementation plans must consider not only system design and failure modes, but must also be accompanied with the appropriate ''mind shift'' within operations and technical personnel. This is required to ensure completion of both physical and electronic activities, and system design changes are performed conscientiously and with full awareness of MPC&A requirements.

CERTS: Consortium for Electric Reliability Technology Solutions - Research Highlights
Historically, the U.S. electric power industry was vertically integrated, and utilities were responsible for system planning, operations, and reliability management. As the nation moves to a competitive market structure, these functions have been disaggregated, and no single entity is responsible for reliability management. As a result, new tools, technologies, systems, and management processes are needed to manage the reliability of the electricity grid. However, a number of simultaneous trends prevent electricity market participants from pursuing development of these reliability tools: utilities are preoccupied with restructuring their businesses, research funding has declined, and the formation of Independent System Operators (ISOs) and Regional Transmission Organizations (RTOs) to operate the grid means that control of transmission assets is separate from ownership of these assets; at the same time, business uncertainty, and changing regulatory policies have created a climate in which needed investment for transmission infrastructure and tools for reliability management has dried up. To address the resulting emerging gaps in reliability R&D, CERTS has undertaken much-needed public interest research on reliability technologies for the electricity grid. CERTS' vision is to: (1) Transform the electricity grid into an intelligent network that can sense and respond automatically to changing flows of power and emerging problems; (2) Enhance reliability management through market mechanisms, including transparency of real-time information on the status of the grid; (3) Empower customers to manage their energy use and reliability needs in response to real-time market price signals; and (4) Seamlessly integrate distributed technologies--including those for generation, storage, controls, and communications--to support the reliability needs of both the grid and individual customers.

Photovoltaic module reliability workshop
The paper and presentations compiled in this volume form the Proceedings of the fourth in a series of Workshops sponsored by Solar Energy Research Institute (SERI/DOE) under the general theme of photovoltaic module reliability during the period 1986--1990. The reliability Photo Voltaic (PV) modules/systems is exceedingly important along with the initial cost and efficiency of modules if the PV technology has to make a major impact in the power generation market, and for it to compete with the conventional electricity producing technologies. The reliability of photovoltaic modules has progressed significantly in the last few years as evidenced by warranties available on commercial modules of as long as 12 years. However, there is still need for substantial research and testing required to improve module field reliability to levels of 30 years or more. Several small groups of researchers are involved in this research, development, and monitoring activity around the world. In the US, PV manufacturers, DOE laboratories, electric utilities and others are engaged in the photovoltaic reliability research and testing. This group of researchers and others interested in this field were brought together under SERI/DOE sponsorship to exchange the technical knowledge and field experience as related to current information in this important field. The papers presented here reflect this effort.

CM - detect anomalies and diagnose problems that require maintenance. PHM - track damage growth, predict time to failure, and manage subsequent maintenance and operations in such a way to optimize overall system utility against cost. The benefits of CM/PHM are: (1) operate power conversion systems in ways that will preclude predicted failures; (2) reduce unscheduled downtime and thereby reduce costs; and (3) pioneering reliability in SiC and GaN.

The Boiler Reliability Optimization program, which makes use of a number of applicable EPRI technologies, was developed to assess, create, and implement an effective boiler maintenance strategy for the changing business environment.
Photovoltaic performance and reliability workshop
This workshop was the sixth in a series of workshops sponsored by NREL/DOE under the general subject of photovoltaic testing and reliability during the period 1986--1993. PV performance and PV reliability are at least as important as PV cost, if not more. In the US, PV manufacturers, DOE laboratories, electric utilities, and others are engaged in the photovoltaic reliability research and testing. This group of researchers and others interested in the field were brought together to exchange the technical knowledge and field experience as related to current information in this evolving field of PV reliability. The papers presented here reflect this effort since the last workshop held in September, 1992. The topics covered include: cell and module characterization, module and system testing, durability and reliability, system field experience, and standards and codes.

Building a winning electric utility organization
The key factor that will differentiate the winners and losers is the speed with which they build their skills and enhance their performance focus. Setting the {open_quote}right{close_quote} aspirations, then effectively managing the change process, will be critical for winning power companies. Historically, only certain dimensions of organizational performance have been critical to an electric utility`s financial success. As a result, utilities understandably focused on achieving high levels of customer satisfaction and reliability, excellent regulatory relationships, and safe and environmentally acceptable operations. However, as the power industry undergoes fundamental change, obtaining superior organizational performance will become much more crucial and difficult. Given the importance of meeting these organizational challenges head on, the authors believe CEOs can only address them by taking an important step back from day-to-day activities to define what high performance really means in the future competitive world and what steps should be taken to achieve their aspirations. To facilitate this rethink - which senior managers should view as a multiyear process - utilities need to do three things in an iterative way: (1) energize the transformation with the right performance aspirations. (2) Tailor a coherent change program to the company`s unique starting position. (3) Manage the change process to build a skill-based and performance-focused organization.

Managing electricity reliability risk through the futures markets
In competitive electricity markets, the vertically integrated utilities that were responsible for ensuring system reliability in their own service territories, or groups of territories, often cease to exist. Typically, the burden falls to an independent system operator (ISO) to insure that enough ancillary services (AS) are available for safe, stable, and reliable operation of the grid, typically defined, in part, as compliance with officially approved engineering specifications for minimum levels of AS. In order to characterize the behavior of market participants (generators, retailers, and an ISO) in a competitive electricity market with reliability requirements, we model a spot market for electricity and futures markets for both electricity and AS. By assuming that each participant seeks to maximize its expected utility of wealth and that all markets clear, we solve for the optional quantities of electricity and AS traded in each market by all participants, as well as the corresponding market-clearing prices. We show that future prices for both electricity and AS depend on expectations of the spot price, statistical aspects of system demand, and production cost parameters. More important, our model captures the fact that electricity and AS are substitute products for the generators, implying that anticipated changes in the spot market will affect the equilibrium futures positions of both electricity and AS. We apply our model to the California electricity and AS markets to test its viability.

Managing Reliability in the 21st Century
The rapid pace of change at Ike end of the 20th Century should continue unabated well into the 21st Century. The driver will be the marketplace imperative of "faster, better, cheaper." This imperative has already stimulated a revolution-in-engineering in design and manufacturing. In contrast, to date, reliability engineering has not undergone a similar level of change. It is critical that we implement a corresponding revolution-in-reliability-engineering as we enter the new millennium. If we are still using 20th Century reliability approaches in the 21st Century, then reliability issues will be the limiting factor in faster, better, and cheaper. At the heart of this reliability revolution will be a science-based approach to reliability engineering. Science-based reliability will enable building-in reliability, application-specific products, virtual qualification, and predictive maintenance. The purpose of this paper is to stimulate a dialogue on the future of reliability engineering. We will try to gaze into the crystal ball and predict some key issues that will drive reliability programs in the new millennium. In the 21st Century, we will demand more of our reliability programs. We will need the ability to make accurate reliability predictions that will enable optimizing cost, performance and time-to-market to meet the needs of every market segment. We will require that all of these new capabilities be in place prior to the stint of a product development cycle. The management of reliability programs will be driven by quantifiable metrics of value added to the organization business objectives.

Measurement Practices for Reliability and Power Quality
This report provides a distribution reliability measurement ''toolkit'' that is intended to be an asset to regulators, utilities and power users. The metrics and standards discussed range from simple reliability, to power quality, to the new blend of reliability and power quality analysis that is now developing. This report was sponsored by the Office of Electric Transmission and Distribution, U.S. Department of Energy (DOE). Inconsistencies presently exist in commonly agreed-upon practices for measuring the reliability of the distribution systems. However, efforts are being made by a number of organizations to develop solutions. In addition, there is growing interest in methods or standards for measuring power quality, and in defining power quality levels that are acceptable to various industries or user groups. The problems and solutions vary widely among geographic areas and among large investor-owned utilities, rural cooperatives, and municipal utilities; but there is still a great degree of commonality. Industry organizations such as the National Rural Electric Cooperative Association (NRECA), the Electric Power Research Institute (EPRI), the American Public Power Association (APPA), and the Institute of Electrical and Electronics Engineers (IEEE) have made tremendous strides in preparing self-assessment templates, optimization guides, diagnostic techniques, and better definitions of reliability and power quality measures. In addition, public utility commissions have developed codes and methods for assessing performance that consider local needs. There is considerable overlap among these various organizations, and we see real opportunity and value in sharing these methods, guides, and standards in this report. This report provides a ''toolkit'' containing synopses of noteworthy reliability measurement practices. The toolkit has been developed to address the interests of three groups: electric power users, utilities, and regulators. The report will also serve to support activities to develop and share information among industry and regulatory participants about critical resources and practices. The toolkit has been developed by investigating the status of indices and definitions, surveying utility organizations on information sharing, and preparing summaries of reliability standards and monitoring requirements--the issues, needs, work under way, existing standards, practices and guidelines--for the following three classifications: (1) terms and definitions of reliability; (2) power quality standards, guidelines, and measurements; and (3) activities and organizations developing and sharing information on distribution reliability. As these synopses of reliability measurement practices are provided, it must be noted that an economic penalty may be associated with requiring too high a reliability level from the distribution system for all customers. It may be appropriate for the distribution system to supply only some base, generally accepted level of reliability. This base level would be adequate for the majority of customers. Users who need a higher level may find it economical to supply using distributed energy resources (DER) and other local solutions to reliability and power quality needs. Local solutions implemented by the customer may be the most cost-effective method for addressing the more stringent needs of a digital economy. These local solutions include energy storage, small distributed generators, and microgrids. This report also considers the market's role in addressing reliability issues and requirements. The customer's needs are discussed in view of issues such as power quality requirements of digital electronic equipment, the cost of outages, the cost of storage and new infrastructure, and natural gas prices. The market role in addressing these issues and requirements is explored. The economic considerations associated with the reliability issues are discussed, as well as the levels at which these economic decisions could be made.

Grid reliability management tools
To summarize, Consortium for Electric Reliability Technology Solutions (CERTS) is engaged in a multi-year program of public interest R&D to develop and prototype software tools that will enhance system reliability during the transition to competitive markets. The core philosophy embedded in the design of these tools is the recognition that in the future reliability will be provided through market operations, not the decisions of central planners. Embracing this philosophy calls for tools that: (1) Recognize that the game has moved from modeling machine and engineering analysis to simulating markets to understand the impacts on reliability (and vice versa); (2) Provide real-time data and support information transparency toward enhancing the ability of operators and market participants to quickly grasp, analyze, and act effectively on information; (3) Allow operators, in particular, to measure, monitor, assess, and predict both system performance as well as the performance of market participants; and (4) Allow rapid incorporation of the latest sensing, data communication, computing, visualization, and algorithmic techniques and technologies.

Demand Response For Power System Reliability: FAQ
Demand response is the most underutilized power system reliability resource in North America. Technological advances now make it possible to tap this resource to both reduce costs and improve. Misconceptions concerning response capabilities tend to force loads to provide responses that they are less able to provide and often prohibit them from providing the most valuable reliability services. Fortunately this is beginning to change with some ISOs making more extensive use of load response. This report is structured as a series of short questions and answers that address load response capabilities and power system reliability needs. Its objective is to further the use of responsive load as a bulk power system reliability resource in providing the fastest and most valuable ancillary services.

Substation Reliability Centered Maintenance
Substation Reliability Centered Maintenance (RCM) is a technique that is used to develop maintenance plans and criteria so the operational capability of substation equipment is achieved, restored, or maintained. The objective of the RCM process is to focus attention on system equipment in a manner that leads to the formulation of an optimal maintenance plan. The RCM concept originated in the airline industry in the 1970s and has been used since 1985 to establish maintenance requirements for nuclear power plants. The RCM process is initially applied during the design and development phase of equipment or systems on the premise that reliability is a design characteristic. It is then reapplied, as necessary, during the operational phase to sustain a more optimal maintenance program based on actual field experiences. The purpose of the RCM process is to develop a maintenance program that provides desired or specified levels of operational safety and reliability at the lowest possible overall cost. The objectives are to predict or detect and correct incipient failures before they occur or before they develop into major defects, reduce the probability of failure, detect hidden problems, and improve the cost-effectiveness of the maintenance program. RCM accomplishes two basic purposes: (1) It identifies in real-time incipient equipment problems, averting potentially expensive catastrophic failures by communicating potential problems to appropriate system operators and maintenance personnel. (2) It provides decision support by recommending, identifying, and scheduling preventive maintenance. Recommendations are based on maintenance criteria, maintenance history, experience with similar equipment, real-time field data, and resource constraints. Hardware and software are used to accomplish these two purposes.

Component reliability testing
Component and system reliability of active solare energy systems continues to be a major concern of designers, manufacturers, installers, and consumers. Six test loops were constructed at the Solar Energy Research Institute in Golden, Colorado, to thermally cycle active solar energy system components. Drain valves, check valves, air vents, vacuum breakers, tempering valves, and polybutylene pipe were included in the testing. Test results show poor reliabiity of some of the components and limited performance from others. The results lead to a better understanding of certain failures in the field and present designers with realistic expectations for these components.

Marketing Reordering of the Electric Utility Industry
ELCON is a group of large industrial consumers of electricity with facilities in most of the 50 states and many foreign countries. Our members produce a wide range of products including steel, aluminum, chemicals, industrial gases, glass, motor vehicles, textiles and food. ELCON members consume approximately ten percent of all electricity sold to industrial customers and nearly five percent of all electricity consumed in the United States. We require an adequate and reliable supply of electricity at reasonable prices, so as you can imagine, we have a continuing interest in all aspects of the production, pricing, and delivery of electricity. ELCON member companies believe strongly that the electric utility industry is undergoing a market reordering that is being shaped by technological, institutional and legal forces. We see technical developments that now make small-scale generation economically attractive, if not downright desirable. Key regulatory and consumer institutions are taking fresh, new looks at issues such as wheeling and access to the grid that used to be considered sacred and untouchable. Some states are passing laws and implementing regulations that will require new thinking and new operating procedures on the part of utilities and consumers. I see these developments as logical reactions to changes in market forces. Change will take place. The relevant questions are: How will regulators and policy makers be influenced by market forces in the future? And: Will utilities, consumers and regulators attempt to benefit from market pressures or, alternatively, try to oppose what I believe is inevitable evolution to a more market-oriented electric industry?

Cable Reliability Management Strategies
In previous collaborative research with several utilities, EPRI developed methods for forecasting the failures and cash flows associated with managing a population of underground cable. This study builds on that research and provides a method for developing least-cost repair and replacement policies for such a population. The policies specify when to replace a cable section or an entire circuit, depending on the age of the section and the number of failures the section has experienced.
Congeneration and utilities: Status and prospects: Final report
The cogeneration industry has grown and changed considerably since the passage of the Public Utility Regulatory Policies Act (PURPA) in 1978. It has moved from infancy to a major industry that must be addressed in electric utility resource planning. This report examines the utility perspective on cogeneration. The report begins with a brief outline of the history of the US cogeneration industry, including an in-depth look at recent developments. An assessment of the industry as it currently stands is then presented. This assessment includes a look at who is cogenerating now and who is likely to be cogenerating in the future. It also includes an analysis of the key market sensitivities and how they affect the individuals who must make the decisions to cogenerate. These discussions provide a framework for the central issue addressed in the next section: the effect of cogeneration on the electric utilities. After the alternative responses to cogeneration are outlined, the report details the impacts of cogeneration on utility planning and policy. Special utility concerns relative to cogeneration are raised including potential ratemaking approaches, the issue of cogeneration reliability and approaches to planning for it, and the costs and benefits of cogeneration to non-participant ratepayers. Next the planning and economic benefits which can accrue from utility ownership of and participation in cogeneration projects are discussed in the context of cogeneration as an electric utility opportunity. The final sections of the report define and classify various types of cogeneration technologies and outline the current status of EPRI's cogeneration research. 21 figs., 22 tabs.

Consider insulation reliability
This paper reports that when calcium silicate and two brands of mineral wool were compared in a series of laboratory tests, calcium silicate was more reliable. And in-service experience with mineral wool at a Canadian heavy crude refinery provided examples of many of the lab's findings. Lab tests, conducted under controlled conditions following industry accepted practices, showed calcium silicate insulation was stronger, tougher and more durable than the mineral wools to which it was compared. For instance, the calcium silicate insulation exhibited only some minor surface cracking when heated to 1,200[degrees]F (649[degrees]C), while the mineral wools suffered binder burnout resulting in sagging, delamination and a general loss of dimensional stability.

Structural reliability analysis and seismic risk assessment
This paper presents a reliability analysis method for safety evaluation of nuclear structures. By utilizing this method, it is possible to estimate the limit state probability in the lifetime of structures and to generate analytically the fragility curves for PRA studies. The earthquake ground acceleration, in this approach, is represented by a segment of stationary Gaussian process with a zero mean and a Kanai-Tajimi Spectrum. All possible seismic hazard at a site represented by a hazard curve is also taken into consideration. Furthermore, the limit state of a structure is analytically defined and the corresponding limit state surface is then established. Finally, the fragility curve is generated and the limit state probability is evaluated. In this paper, using a realistic reinforced concrete containment as an example, results of the reliability analysis of the containment subjected to dead load, live load and ground earthquake acceleration are presented and a fragility curve for PRA studies is also constructed.

Continuous Reliability Enhancement for Wind (CREW) database : wind plant reliability benchmark.
To benchmark the current U.S. wind turbine fleet reliability performance and identify the major contributors to component-level failures and other downtime events, the Department of Energy funded the development of the Continuous Reliability Enhancement for Wind (CREW) database by Sandia National Laboratories. This report is the third annual Wind Plant Reliability Benchmark, to publically report on CREW findings for the wind industry. The CREW database uses both high resolution Supervisory Control and Data Acquisition (SCADA) data from operating plants and Strategic Power Systems' ORAPWind%C2%AE (Operational Reliability Analysis Program for Wind) data, which consist of downtime and reserve event records and daily summaries of various time categories for each turbine. Together, these data are used as inputs into CREW's reliability modeling. The results presented here include: the primary CREW Benchmark statistics (operational availability, utilization, capacity factor, mean time between events, and mean downtime); time accounting from an availability perspective; time accounting in terms of the combination of wind speed and generation levels; power curve analysis; and top system and component contributors to unavailability.

Reliability-based design optimization using efficient global reliability analysis.
Finding the optimal (lightest, least expensive, etc.) design for an engineered component that meets or exceeds a specified level of reliability is a problem of obvious interest across a wide spectrum of engineering fields. Various methods for this reliability-based design optimization problem have been proposed. Unfortunately, this problem is rarely solved in practice because, regardless of the method used, solving the problem is too expensive or the final solution is too inaccurate to ensure that the reliability constraint is actually satisfied. This is especially true for engineering applications involving expensive, implicit, and possibly nonlinear performance functions (such as large finite element models). The Efficient Global Reliability Analysis method was recently introduced to improve both the accuracy and efficiency of reliability analysis for this type of performance function. This paper explores how this new reliability analysis method can be used in a design optimization context to create a method of sufficient accuracy and efficiency to enable the use of reliability-based design optimization as a practical design tool.

Industry/Utility Partnerships: Formula for Success
Industry/utility partnerships are created when both parties work productively toward common goals. American industry faces tough global competition and to be successful must create and operate modern production facilities. Cost and energy efficient electrotechnologies play a critical role in their competitiveness. Utilities can play a central role in industrial competitiveness, not only by providing competitively priced and reliable power, but also by helping their customers to identify and implement the most appropriate technologies. When the correct environment is created, both win. Industry reduces costs and produces high quality products. The utility gains customer loyalty and achieves business success.

Performance issues for a changing electric power industry
Extremely cold weather created record demands for electricity in the eastern two-thirds of the United States during the week of January 16, 1994. Fuel-related problems, mostly the result of transportation constraints resulting from ice accumulation on roads and water-ways, and unexpected generating capacity outages at utilities and nonutilities resulted in demand not being met. Some utilities asked nonessential customers along with State governments and a portion of the Federal Government to shut down. Two electric control areas, the Pennsylvania-New Jersey-Maryland Interconnection (PJM) and Virginia Electric & Power Company (VEPCO), instituted rolling blackouts. This disturbance was reported widely in the press and, along with other disturbances, peaked renewed interest in the reliability of the electric power system. The renewed interest in reliability has coincided with substantial changes that are beginning to occur in the structure and competitiveness of the electric power industry. Juxtaposing the question of reliability and the issue of changing industry structure leads to the central concern of this report: What effect, if any, will the changing structure of the industry have on the reliability of the system?

Supply management: The next competitive advantage for utilities
Almost three-quarters of the cost of operating a typical utility is attributable to supply management activities - planning, acquisition, handling, disposition, and payment for materials, services, and fuel. Reducing their costs can substantially improve one`s competitive position. Three performance indicators will be paramount in determining which utilities survive and prosper: (1) Price. Energy is a commodity. As such, the principal driver of market penetration in the new era of wholesale and retail wheeling will be price. Therefore, the determinant of success will be the ability to provide products and services to the marketplace at the lowest possible price. (2) Service quality. Beyond price, the most meaningful differentiation among energy delivery companies is in the perceived quality of services provided. Customer service and reliability will be the key means by which a provider differentiates itself, positively or negatively, from the competition. (3) Earnings growth. With the application of incentive regulation, earnings will be governed by a company`s ability to compete successfully in the market. This will place extreme pressure on utilities to enhance revenues - which is difficult in a mature market - and/or to reduce costs through productivity gains and process changes.

Real Time Grid Reliability Management 2005
The increased need to manage California?s electricity grid in real time is a result of the ongoing transition from a system operated by vertically-integrated utilities serving native loads to one operated by an independent system operator supporting competitive energy markets. During this transition period, the traditional approach to reliability management -- construction of new transmission lines -- has not been pursued due to unresolved issues related to the financing and recovery of transmission project costs. In the absence of investments in new transmission infrastructure, the best strategy for managing reliability is to equip system operators with better real-time information about actual operating margins so that they can better understand and manage the risk of operating closer to the edge. A companion strategy is to address known deficiencies in offline modeling tools that are needed to ground the use of improved real-time tools. This project: (1) developed and conducted first-ever demonstrations of two prototype real-time software tools for voltage security assessment and phasor monitoring; and (2) prepared a scoping study on improving load and generator response models. Additional funding through two separate subsequent work authorizations has already been provided to build upon the work initiated in this project.

Cogeneration - A Utility Perspective
Cogeneration has become an extremely popular subject when discussing conservation and energy saving techniques. One of the key factors which effect conservation is the utility viewpoint on PURPA and cogeneration rule making. These topics are discussed from a utility perspective as how they influence utility participation in future projects. The avoided cost methodology is examined, and these payments for sale of energy to the utility are compared with utility industrial rates. In addition to utilities and industry, third party owner/operation is also a viable option to cogeneration. These options are also discussed as to their impact on the utility and the potential of these ownership arrangements.

Real-Time Grid Reliability Management PIER Final Project Report
Real-Time Grid Reliability Management PIER Final Project Report Real-Time Grid Reliability Management PIER Final Project Report Title Real-Time Grid Reliability Management PIER Final Project Report Publication Type Report Year of Publication 2008 Authors Eto, Joseph H., Manu Parashar, Bernard C. Lesieutre, and Nancy J. Lewis Pagination 62 Date Published 12/2008 Publisher LBNL City Berkeley Keywords consortium for electric reliability technology solutions (certs), energy analysis and environmental impacts department Abstract The increased need to manage California's electricity grid in real time is a result of the ongoing transition from a system operated by vertically integrated utilities serving native loads to one operated by an independent system operator supporting competitive energy markets. During this transition period, the traditional approach to reliability management - construction of new transmission lines - has not been pursued due to unresolved issues related to the financing and recovery of transmission project costs. In the absence of investments in new transmission infrastructure, the best strategy for managing reliability is to equip system operators with better real-time information about actual operating margins so that they can better understand and manage the risk of operating closer to the edge. A companion strategy is to address known deficiencies in offline modeling tools that are needed to ground the use of improved real-time tools.

Replacement energy, capacity, and reliability costs for permanent nuclear reactor shutdowns
Average replacement power costs are estimated for potential permanent shutdowns of nuclear electricity-generating units. Replacement power costs are considered to include replacement energy, capacity, and reliability cost components. These estimates were developed to assist the US Nuclear Regulatory Commission in evaluating regulatory issues that potentially affect changes in serious reactor accident frequencies. Cost estimates were derived from long-term production-cost and capacity expansion simulations of pooled utility-system operations. Factors that affect replacement power cost, such as load growth, replacement sources of generation, and capital costs for replacement capacity, were treated in the analysis. Costs are presented for a representative reactor and for selected subcategories of reactors, based on estimates for 112 individual reactors.

Gearbox Reliability Collaborative Bearing Calibration
NREL has initiated the Gearbox Reliability Collaborative (GRC) to investigate the root cause of the low wind turbine gearbox reliability. The GRC follows a multi-pronged approach based on a collaborative of manufacturers, owners, researchers and consultants. The project combines analysis, field testing, dynamometer testing, condition monitoring, and the development and population of a gearbox failure database. At the core of the project are two 750kW gearboxes that have been redesigned and rebuilt so that they are representative of the multi-megawatt gearbox topology currently used in the industry. These gearboxes are heavily instrumented and are tested in the field and on the dynamometer. This report discusses the bearing calibrations of the gearboxes.

Joint DOE/industry photovoltaic system reliability program
To achieve the lowest life-cycle cost (LCC), photovoltaic (PV) systems must have the optimum mix of low first cost, low operation and maintenance (O&M) cost, and high availability. Additionally, the long-term health of the photovoltaic (PV) industry requires that PV systems work as expected. Although PV modules now enjoy high reliability due to a significant multi-year effort by both the U.S. Department of Energy (DOE) and industry, the same is not always true of PV systems. Even for systems that do operate reliably, customers, suppliers, and manufacturers can benefit from knowing what O&M expenses to expect. This knowledge will reduce technology risk to the customer and improve likelihood of commitment to PV projects. System integrators and utilities may benefit from O&M cost information to improve system designs, to properly price service agreements and warranties, and to optimize maintenance strategies. The DOE and component manufacturers may benefit from identifying cost drivers to optimally focus research and quality assurance resources to improve product reliability. This paper discusses the first of five tasks identified for this project, quantifying system reliability and life cycle cost by collecting, analyzing and reporting data on PV system reliability and cost. Industry participants collect the necessary O&M data on systems they are monitoring. Sandia provides support in the form of assistance identifying data that needs to be collected, helping develop forms or databases to collect the data, and analyzing the data.

Technology Advancements to Support Growth in Geothermal Power Sales in a Dynamic Utility Market
We are assembled today to discuss the opportunities and challenges for expanding the sales of geothermally-generated electric power in a competitive utility market. First, however, I would like to note that growth in geothermal sales might not be a germane topic were it not for the early participation in the development of the geothermal industry by utilities themselves. Without their contributions to research and development, environmental breakthroughs, and, perhaps, above all, their early use of geothermal power and continuing investment in the industry, we might still be at ''Square One''--confronting inhibiting doubts of the energy utilization industry. I feel certain that utility involvement has served to inspire far greater confidence in the reliability of the resource on the part of other utilities and other investors than could have been generated by federal programs and/or the resource developer arm of the geothermal community. While acknowledging that we have not completely resolved all problems which geothermal energy faced 20 years ago--confidence, institutional restraints, environmental compliance, and technical and economic uncertainties--this audience and our predecessors have addressed them, individually and collectively, and, to a large extent, we have surmounted them. But it took generation or contracted purchase of geothermal power by utilities--whatever their discrete reasons for doing so--to demonstrate to the public and government regulators that there is a place for geothermal power in the service areas of large utilities. In addition, in using an alternative fuel, the participating utilities have already exposed themselves to changing concepts and practices in their industry.

Gas utilization technologies
One of the constant challenges facing the research community is the identification of technology needs 5 to 15 years from now. A look back into history indicates that the forces driving natural gas research have changed from decade to decade. In the 1970s research was driven by concerns for adequate supply; in the 1980s research was aimed at creating new markets for natural gas. What then are the driving forces for the 1990s? Recent reports from the natural gas industry have helped define a new direction driven primarily by market demand for natural gas. A study prepared by the Interstate Natural Gas Association of America Foundation entitled ``Survey of Natural Research, Development, and Demonstration RD&D Priorities`` indicated that in the 1990s the highest research priority should be for natural gas utilization and that technology development efforts should not only address efficiency and cost, but environmental and regulatory issues as well. This study and others, such as the report by the American Gas Association (A.G.A.) entitled ``Strategic Vision for Natural Gas Through the Year 2000,`` clearly identify the market sectors driving today`s technology development needs. The biggest driver is the power generation market followed by the industrial, transportation, appliance, and gas cooling markets. This is best illustrated by the GRI 1994 Baseline Projection on market growth in various sectors between the year 1992 and 2010. This paper highlights some of the recent technology developments in each one of these sectors.

Utility advanced turbine systems (ATS) technology readiness testing
The overall objective of the Advanced Turbine System (ATS) Phase 3 Cooperative Agreement between GE and the US Department of Energy (DOE) is the development of a highly efficient, environmentally superior, and cost-competitive utility ATS for base-load utility-scale power generation, the GE 7H (60 Hz) combined cycle power system, and related 9H (50 Hz) common technology. The major effort will be expended on detail design. Validation of critical components and technologies will be performed, including: hot gas path component testing, sub-scale compressor testing, steam purity test trials, and rotational heat transfer confirmation testing. Processes will be developed to support the manufacture of the first system, which was to have been sited and operated in Phase 4 but will now be sited and operated commercially by GE. This change has resulted from DOE's request to GE for deletion of Phase 4 in favor of a restructured Phase 3 (as Phase 3R) to include full speed, no load (FSNL) testing of the 7H gas turbine. Technology enhancements that are not required for the first machine design but will be critical for future ATS advances in performance, reliability, and costs will be initiated. Long-term tests of materials to confirm design life predictions will continue. A schematic of the GE H machine is shown.

Using consensus building to improve utility regulation
The utility industry and its regulatory environment are at a crossroads. Utilities, intervenors and even public utility commissions are no longer able to initiate and sustain changes unilaterally. Traditional approaches to regulation are often contentious and costly, producing results that are not perceived as legitimate or practical. Consensus building and alternative dispute resolution have the potential to help utilities, intervenors and regulators resolve a host of regulatory issues. This book traces the decline of consensus in utility regulation and delineates current controversies. It presents the theory and practice of alternative dispute resolution in utility regulation and offers a framework for evaluating the successes and failures of attempts to employ these processes. Four regulatory cases are analyzed in detail: the Pilgrim nuclear power plant outage settlement, the use of DSM collaboratives, the New Jersey resource bidding policy and the formation of integrated resource management rules in Massachusetts.

Utilities weather the storm
Utilities must restore power to storm-damaged transmission and distribution systems, even if it means going out in ice storms or during lightning and hurricane conditions. Weather forecasting helps utilities plan for possible damage as well as alerting them to long-term trends. Storm planning includes having trained repair personnel available and adjusting the system so that less power imports are needed. Storm damage response requires teamwork and cooperation between utilities. Utilities can strengthen equipment in storm-prone or vulnerable areas, but good data are necessary to document the incidence of lighning strikes, hurricanes, etc. 2 references, 8 figures.

The Role of Demand Resources In Regional Transmission Expansion Planning and Reliable Operations
Investigating the role of demand resources in regional transmission planning has provided mixed results. On one hand there are only a few projects where demand response has been used as an explicit alternative to transmission enhancement. On the other hand there is a fair amount of demand response in the form of energy efficiency, peak reduction, emergency load shedding, and (recently) demand providing ancillary services. All of this demand response reduces the need for transmission enhancements. Demand response capability is typically (but not always) factored into transmission planning as a reduction in the load which must be served. In that sense demand response is utilized as an alternative to transmission expansion. Much more demand response is used (involuntarily) as load shedding under extreme conditions to prevent cascading blackouts. The amount of additional transmission and generation that would be required to provide the current level of reliability if load shedding were not available is difficult to imagine and would be impractical to build. In a very real sense demand response solutions are equitably treated in every region - when proposed, demand response projects are evaluated against existing reliability and economic criteria. The regional councils, RTOs, and ISOs identify needs. Others propose transmission, generation, or responsive load based solutions. Few demand response projects get included in transmission enhancement plans because few are proposed. But this is only part of the story. Several factors are responsible for the current very low use of demand response as a transmission enhancement alternative. First, while the generation, transmission, and load business sectors each deal with essentially the same amount of electric power, generation and transmission companies are explicitly in the electric power business but electricity is not the primary business focus of most loads. This changes the institutional focus of each sector. Second, market and reliability rules have, understandably, been written around the capabilities and limitations of generators, the historic reliability resources. Responsive load limitations and capabilities are often not accommodated in markets or reliability criteria. Third, because of the institutional structure, demand response alternatives are treated as temporary solutions that can delay but not replace transmission enhancement. Financing has to be based on a three to five year project life as opposed to the twenty to fifty year life of transmission facilities. More can be done to integrate demand response options into transmission expansion planning. Given the societal benefits it may be appropriate for independent transmission planning organizations to take a more proactive role in drawing demand response alternatives into the resource mix. Existing demand response programs provide a technical basis to build from. Regulatory and market obstacles will have to be overcome if demand response alternatives are to be routinely considered in transmission expansion planning.
Utility downsizings pose a dilemma for regulators
A utility's job-generating potential is critical to most local economies. At the same time, however, high utility employment levels maintain an upward pressure on rates, an effect that does not escape regulators' notice, especially during an economic slowdown. More than on regulator has been heard to say that hard-hit ratepayers should not be called on to support what some may seen as a bloated utility workforce scaled to better times. To complicate things even more, popular cost-cutting goals that include improving productivity and relying more on conservation could mean fewer jobs, at least at the utility. What's more, utility rates play a significant role in how local industries and businesses respond to an economic slowdown. This interplay of economic forces has complicated the ratemaking process. The size of a utility's workforce is an issue of growing significance in rate hearings. Forecasts for test-period salary and wage expenses are less reliable. Early retirement plans promise future savings for ratepayers, but at a cost today.
Cross, P.S.
The Utilities' Role in Conservation and Cogeneration
The electric utility industry is uniquely qualified and positioned to serve as an effective 'deliverer' of energy conservation services and alternative energy supply options, such as cogeneration, rather than merely as a 'facilitator' of their development by other parties. Amendments to current legislation are required to remove the barriers to utility participation and to provide electric utilities with appropriate incentives to deliver conservation and alternative power sources in their own self-interest. That utility self-interest can take the form of benefits to its ratepayers or stockholders -- or, optimally, to both. Moreover, adequate, reliable and economical electric energy from the utility grid is vital to our nation's economic well-being. A financially healthy electric utility industry is essential to the realization of this goal. Therefore, as we continue to refine a national energy policy, we must give this requisite careful attention when developing positions on conservation, cogeneration, equitable rate design, and all of the other elements, for they are inextricably related.

Human Reliability Considerations for Small Modular Reactors
Small modular reactors (SMRs) are a promising approach to meeting future energy needs. Although the electrical output of an individual SMR is relatively small compared to that of typical commercial nuclear plants, they can be grouped to produce as much energy as a utility demands. Furthermore, SMRs can be used for other purposes, such as producing hydrogen and generating process heat. The design characteristics of many SMRs differ from those of current conventional plants and may require a distinct concept of operations. The U.S. Nuclear Regulatory Commission (NRC) conducted research to examine the human factors engineering and the operational aspects of SMRs. The research identified thirty potential human-performance issues that should be considered in the NRC's reviews of SMR designs and in future research activities. The purpose of this report is to illustrate how the issues can support SMR probabilistic risk analyses and their review by identifying potential human failure events for a subset of the issues. As part of addressing the human contribution to plant risk, human reliability analysis practitioners identify and quantify the human failure events that can negatively impact normal or emergency plant operations. The results illustrated here can be generalized to identify additional human failure events for the issues discussed and can be applied to those issues not discussed in this report.

Reliable Gas Turbine Output: Attaining Temperature Independent Performance
Improvements in gas turbine efficiency, coupled with dropping gas prices, has made gas turbines a popular choice of utilities to supply peaking as well as base load power in the form of combined cycle power plants. Today, because of the gas turbine's compactness, low maintenance, and high levels of availability, it is the major option for future power generation. One inherent disadvantage of gas turbines is the degradation of output as the ambient air temperature increases. This reduction in output during times of peak load create a reliability concern as more gas turbines are added to the electric system. A 10% reduction in gas turbine output, when it comprises only 10% of the electric system, does not cause reliability concerns. A 10% reduction in gas turbine output, when it comprises 50% of the electric system, could create reliability and operational problems. This paper explores the potential for maintaining constant, reliable outputs from gas turbines by cooling ambient air temperatures before the air is used in the compressor section of the gas turbine.

A Reliable Natural Language Interface
As household appliances grow in complexity and sophistication, they become harder and harder to use, particularly because of their tiny display screens and limited keyboards. This paper describes a strategy for building natural language interfaces to appliances that circumvents these problems. Our approach leverages decades of research on planning and natural language interfaces to databases by reducing the appliance problem to the database problem; the reduction provably maintains desirable properties of the database interface. The paper goes on to describe the implementation and evaluation of the EXACT interface to appliances, which is based on this reduction. EXACT maps each English user request to an SQL query, which is transformed to create a PDDL goal, and uses the Blackbox planner [13] to map the planning problem to a sequence of appliance commands that satisfy the original request. Both theoretical arguments and experimental evaluation show that EXACT is highly reliable.

Report on the analysis of field data relating to the reliability of solar hot water systems.
Utilities are overseeing the installations of thousand of solar hot water (SHW) systems. Utility planners have begun to ask for quantitative measures of the expected lifetimes of these systems so that they can properly forecast their loads. This report, which augments a 2009 reliability analysis effort by Sandia National Laboratories (SNL), addresses this need. Additional reliability data have been collected, added to the existing database, and analyzed. The results are presented. Additionally, formal reliability theory is described, including the bathtub curve, which is the most common model to characterize the lifetime reliability character of systems, and for predicting failures in the field. Reliability theory is used to assess the SNL reliability database. This assessment shows that the database is heavily weighted with data that describe the reliability of SHW systems early in their lives, during the warranty period. But it contains few measured data to describe the ends of SHW systems lives. End-of-life data are the most critical ones to define sufficiently the reliability of SHW systems in order to answer the questions that the utilities pose. Several ideas are presented for collecting the required data, including photometric analysis of aerial photographs of installed collectors, statistical and neural network analysis of energy bills from solar homes, and the development of simple algorithms to allow conventional SHW controllers to announce system failures and record the details of the event, similar to how aircraft black box recorders perform. Some information is also presented about public expectations for the longevity of a SHW system, information that is useful in developing reliability goals.

High reliability plastic packaging for microelectronics
Goal was Assembly Test Chips (ATCs) which could be used for evaluating plastic encapsulation technologies. Circuits were demonstrated for measuring Au-Al wirebond and Al metal corrosion failure rates during accelerated temperature and humidity testing. The test circuits on the ATC02.5 chip were very sensitive to extrinsic or processing induced failure rates. Accelerated aging experiments were conducted with unpassivated triple track Al structures on the ATC02.6 chip; the unpassivated tracks were found to be very sensitive to particulate contamination. Some modifications to existing circuitry were suggested. The piezoresistive stress sensing circuitry designed for the ATC04 test chip was found suitable for determining the change in the state of mechanical stress at the die when both initial and final measurements were made near room temperature (RT). Attempt to measure thermal stress between RT and a typical polymer glass transition temperature failed because of excessive die resistor- substrate leakage currents at the high temperature end; suitable circuitry changes were developed to overcome this problem. One temperature and humidity experiment was conducted with Sandia developed static radom access memory parts to examine non-corrosion CMOS failures; this objective was not achieved, but corrosion failure at the metal to Si contacts on the die surface could be detected. This 2-year effort resulted in new designs for test circuits which could be used on an advanced ATC for reliability assessment in Defense Programs electronics development projects.

Wind forecasting objectives for utility schedulers and energy traders
The wind energy industry and electricity producers can benefit in a number of ways from increased wind forecast accuracy. Higher confidence in the reliability of wind forecasts can help persuade an electric utility to increase the penetration of wind energy into its operating system and to augment the capacity value of wind electric generation. Reliable forecasts can also assist daily energy traders employed by utilities in marketing the available and anticipated wind energy to power pools and other energy users. As the number of utilities with wind energy experience grows, and wind energy penetration levels increase, the need for reliable wind forecasts will likely grow as well. This period of wind energy growth also coincides with advances in computer weather prediction technology that could lead to more accurate wind forecasts. Thus, it is important to identify the type of forecast information needed by utility schedulers and energy traders. This step will help develop approaches to the challenge of wind forecasting that will result in useful products being supplied to utilities or other energy generating entities. This paper presents the objectives, approach, and current findings of a US Department of Energy National Renewable Energy Laboratory (DOE/NREL) initiative to develop useful wind forecasting tools for utilities involved with wind energy generation. The focus of this initiative thus far has been to learn about the needs of prospective utility users. NREL representatives conducted a series of onsite interviews with key utility staff, usually schedulers and research planners, at seven US utilities. The purpose was to ascertain information on actual scheduling and trading procedures, and how utilities could integrate wind forecasting into these activities.

A reliability assessment methodology for distribution systems with distributed generation
Reliability assessment is of primary importance in designing and planning distribution systems that operate in an economic manner with minimal interruption of customer loads. With the advances in renewable energy sources, Distributed Generation (DG), is forecasted to increase in distribution networks. The study of reliability evaluation of such networks is a relatively new area. This research presents a new methodology that can be used to analyze the reliability of such distribution systems and can be applied in preliminary planning studies for such systems. The method uses a sequential Monte Carlo simulation of the distribution system�?s stochastic model to generate the operating behavior and combines that with a path augmenting Max flow algorithm to evaluate the load status for each state change of operation in the system. Overall system and load point reliability indices such as hourly loss of load, frequency of loss of load and expected energy unserved can be computed using this technique. On addition of DG in standby mode of operation at specific locations in the network, the reliability indices can be compared for different scenarios and strategies for placement of DG and their capacities can be determined using this methodology.

Final report : testing and evaluation for solar hot water reliability.
Solar hot water (SHW) systems are being installed by the thousands. Tax credits and utility rebate programs are spurring this burgeoning market. However, the reliability of these systems is virtually unknown. Recent work by Sandia National Laboratories (SNL) has shown that few data exist to quantify the mean time to failure of these systems. However, there is keen interest in developing new techniques to measure SHW reliability, particularly among utilities that use ratepayer money to pay the rebates. This document reports on an effort to develop and test new, simplified techniques to directly measure the state of health of fielded SHW systems. One approach was developed by the National Renewable Energy Laboratory (NREL) and is based on the idea that the performance of the solar storage tank can reliably indicate the operational status of the SHW systems. Another approach, developed by the University of New Mexico (UNM), uses adaptive resonance theory, a type of neural network, to detect and predict failures. This method uses the same sensors that are normally used to control the SHW system. The NREL method uses two additional temperature sensors on the solar tank. The theories, development, application, and testing of both methods are described in the report. Testing was performed on the SHW Reliability Testbed at UNM, a highly instrumented SHW system developed jointly by SNL and UNM. The two methods were tested against a number of simulated failures. The results show that both methods show promise for inclusion in conventional SHW controllers, giving them advanced capability in detecting and predicting component failures.

JMP Applications in Photovoltaic Reliability (Presentation)
The ability to accurately predict power delivery over the course of time is of vital importance to the growth of the photovoltaic (PV) industry. Two key cost drivers are the efficiency with which sunlight is converted into power and secondly how this relationship develops over time. The accurate knowledge of power decline over time, also known as degradation rates, is essential and important to all stakeholders?utility companies, integrators, investors, and scientist alike. Outdoor testing plays a vital part in quantifying degradation rates of different technologies in various climates. Due to seasonal changes, however, several complete cycles (typically 3-5 years) need to be completed traditionally to obtain reasonably accurate degradation rates. In a rapidly evolving industry such a time span is often unacceptable and the need exists to determine degradation rates more accurately in a shorter period of time. Advanced time series modeling such as ARIMA (Autoregressive Integrated Moving Average) modeling can be utilized to decrease the required time span and is compared with some non-linear modeling. In addition, it will be demonstrated how the JMP 9 map feature was used to reveal important technological trends by climate.

Fatigue reliability of wind turbine components
Fatigue life estimates for wind turbine components can be extremely variable due to both inherently random and uncertain parameters. A structural reliability analysis is used to qualify the probability that the fatigue life will fall short of a selected target. Reliability analysis also produces measures of the relative importance of the various sources of uncertainty and the sensitivity of the reliability to each input parameter. The process of obtaining reliability estimates is briefly outlined. An example fatigue reliability calculation for a blade joint is formulated; reliability estimates, importance factors, and sensitivities are produced. Guidance in selecting distribution functions for the random variables used to model the random and uncertain parameters is also provided. 5 refs., 9 figs., 1 tab.

Utility Marketing Strategies & Pricing Trends
Marketing seems to have come out of the utility closet once again, but it is a far sight different from that of the 1970s. While some are still on a �sell, Sell, SELL!� campaign, most are soberly looking at their customers from a different perspective. They are concerned about losing them to other service territories or seeing them vanish to domestic and foreign competition. There is a sense of a �strategic alliance� being sought by the most proactive of utilities in which they become allies of their customers. In this sense, the issue of how much these customers purchased from them vanishes into the shadows of the more important elements of the relationships. Oh sure, there still are some pushing technology as the customer�s answer. And there are others using incentive and other rate gambits to develop strategic load building. But there is a definite trend emerging toward building the relationship for the long haul and putting short range profit or number game objectives on the back burner. This paper investigates the most successful current utility marketing postures, how they are changing, where pricing fits in and what we are likely to see within the next few years. We will also illustrate the potential traps in competitive marketing and customer service that still lie in wait. We still see a major number of current marketing efforts that are unbalanced, unfairly reward luck, are wasteful and counterproductive. As many of you know, we strongly believe marketing must move from technology-based, �silver bullet� competition, frenetic non-competitive load retention dissipation and load claiming to relational-based marketing in which absolute integrity and service and their consequent trust become paramount. We believe utilities must build honest relationships with all their customers, not merely their energy purchasers. These include their fuel suppliers and regulators. When a utility is not trusted, the competitive situation is reduced to that of a commodity supplier in which price and terms constitute the whole of the relationship. Utilities reduced to this level of inadequate customer service ultimately will lose to those that recognize the alternative of adding value. As the nature and consequences of competition increase, so does the importance of breaking from the methods of the past.

Puget Sound Area Electric Reliability Plan : Draft Environmental Impact State.
The Puget Sound Area Electric Reliability Plan Draft Environmental Impact Statement (DEIS) identifies the alternatives for solving a power system problem in the Puget Sound area. This Plan is undertaken by Bonneville Power Administration (BPA), Puget Sound Power Light, Seattle City Light, Snohomish Public Utility District No. 1 (PUD), and Tacoma Public Utilities. The Plan consists of potential actions in Puget Sound and other areas in the State of Washington. A specific need exists in the Puget Sound area for balance between east-west transmission capacity and the increasing demand to import power generated east of the Cascades. At certain times of the year, there is more demand for power than the electric system can supply in the Puget Sound area. This high demand, called peak demand, occurs during the winter months when unusually cold weather increases electricity use for heating. The existing power system can supply enough power if no emergencies occur. However, during emergencies, the system will not operate properly. As demand grows, the system becomes more strained. To meet demand, the rate of growth of demand must be reduced or the ability to serve the demand must be increased, or both. The plan to balance Puget Sound's power demand and supply has these purposes: The plan should define a set of actions that would accommodate ten years of load growth (1994--2003). Federal and State environmental quality requirements should be met. The plan should be consistent with the plans of the Northwest Power Planning Council. The plan should serve as a consensus guideline for coordinated utility action. The plan should be flexible to accommodate uncertainties and differing utility needs. The plan should balance environmental impacts and economic costs. The plan should provide electric system reliability consistent with customer expectations. 29 figs., 24 tabs.

Utility & Regulatory Factors Affecting Cogeneration & Independent Power Plant Design & Operation
In specifying a cogeneration or independent power plant, the owner should be especially aware of the influences which electric utilities and regulatory bodies will have on key parameters such as size, efficiency, design, reliability/ availability, operating capabilities and modes, etc. This paper will note examples of some of the major factors which could impact the project developer and his economics, as well as discuss potential mitigation measures. Areas treated include wheeling, utility ownership interests, dispatchability, regulatory acceptance and other considerations which could significantly affect the plant definition and, as a result, its attendant business and financing structure. Finally, suggestions are also made for facilitating the process of integration with the electric utility.

Substation reliability -- Practical application and system approach
Practical application of reliability analysis was made for the comparison of alternate line and bus arrangements of a future transmission substation with potential savings of up to $3.6 M. The paper describes how both the substation and the power system were simulated by using computer programs STAREL and COMREL. It presents the method used to obtain the most accurate estimates for the outage data of the system components. Finally, it expresses the results with simple reliability indices which can be meaningful for management. The results of the study show the need to include the reliability of the transmission system in a substation reliability evaluation.

Role of wind power in electric utilities
Current estimates suggest that the cost of wind-generated power is likely to be competitive with conventionally generated power in the near future in regions of the United States with favorable winds and high costs for conventionally generated electricity. These preliminary estimates indicate costs of $500 to 700 per installed kW for mass-produced wind turbines. This assessment regarding competitiveness includes effects of reduced reliability of wind power compared to conventional sources. Utilities employing wind power are likely to purchase more peaking capacity and less baseload capacity than they would have otherwise to provide the lowest-cost reserve power. This reserve power is needed mainly when wind outages coincide with peak loads. The monetary savings associated with this shift contribute substantially to the value of wind energy to a utility.

Electricity matters: A new incentives approach for a changing electric industry
The method of regulating a utility`s rates should be changed fundamentally to promote responses to competition. An approach that addresses price caps, profit sharing and affords flexibility in pricing can offer utilities and those they serve a {open_quotes}win-win{close_quotes} scenario. U.S. businesses face fiercely difficult challenges to compete in the global marketplace, requiring many firms to search for new and innovative competitive strategies. American business must make fundamental changes to cope with the forces of competition - or risk going out of business. Electricity suppliers can facilitate economic progress by providing cost-effective, high-quality and reliable service to their customers. But as many utility managers know too well, this goal is not easy to achieve. For regulators, it is important to frame and resolve the issues in a proactive way. At the outset, American electric utilities must have strong incentives to be efficient. The purpose of this paper is to explore some of the incentive regulation techniques, such as price-cap regulation, which U.S. and foreign electric utilities should use to facilitate change. These techniques can better accomodate the current mixed competitive and regulated environment while providing an appropriate transition to a dynamically competitive electric services market.

Consortium for Electric Reliability Technology Solutions Grid of the Future White Paper on Review of Recent Reliability Issues and Systems Events
This report is one of six reports developed under the U.S. Department of Energy (DOE) program in Power System Integration and Reliability (PSIR). The objective of this report is to review, analyze, and evaluate critical reliability issues demonstrated by recent disturbance events in the North America power system. Eleven major disturbances are examined, most occurring in this decade. The strategic challenge is that the pattern of technical need has persisted for a long period of time. For more than a decade, anticipation of market deregulation has been a major disincentive to new investments in system capacity. It has also inspired reduced maintenance of existing assets. A massive infusion of better technology is emerging as the final option to continue reliable electrical services. If an investment in better technology will not be made in a timely manner, then North America should plan its adjustments to a very different level of electrical service. It is apparent that technical operations staff among the utilities can be very effective at marshaling their forces in the immediate aftermath of a system emergency, and that serious disturbances often lead to improved mechanisms for coordinated operation. It is not at all apparent that such efforts can be sustained through voluntary reliability organizations in which utility personnel external to those organizations do most of the technical work. The eastern interconnection shows several situations in which much of the technical support has migrated from the utilities to the Independent System Operator (ISO), and the ISO staffs or shares staff with the regional reliability council. This process may be a natural and very positive consequence of utility restructuring. If so, the process should be expedited in regions where it is less advanced.

Microturbines - an economic and reliability evaluation for commercial, residential, and remote load applications
Most distributed self-generation operates base loaded and in parallel with the electric utility system (1) to minimize peak loads, (2) to improve reliability, (3) to eliminate the need for reserve margin (standby) and (4) may or may not sell back excess generation. This paper examines the economics of distributed microturbine generation operating isolated from the electric utility system and having enough reserve margin to either match or improve the existing reliability of service provided by central station generation and the T and D system. This analysis shows the isolated operation of microturbines with a reserve margin can provide the same or a higher level of reliability as the electric utility, yet the costs can be lower. Sensitivity analysis for different investment costs, O and M costs, fuel costs, reliability, load shapes (load factors), and alternative fuels were performed and the economic comparisons are made in terms of {cents}/kWh. This analysis shows a strong economic preference in applying microturbines to high load factor commercial loads. The cost of standby (from the utility) was found to be from .52 to 2.09{cents}/kWh greater than if the microturbine generation provided its own standby through a built in reserve margin.

Industrial - Utility Cogeneration Systems
Cogeneration may be described as an efficient method for the production of electric power in conjunction with process steam or heat which optimizes the energy supplied as fuel to maximize the energy produced for consumption. In a conventional electric utility power plant, considerable energy is wasted in the form of heat rejection to the atmosphere thru cooling towers, ponds or lakes, or to rivers. In a cogeneration system heat rejection can be minimized by systems which apply the otherwise wasted energy to process systems requiring energy in the form of steam or heat. Texas has a base load of some 75 million pounds per hour of process steam usage, of which a considerable portion could be generated through cogeneration methods. The objective of this paper is to describe the various aspects of cogeneration in a manner which will illustrate the energy saving potential available utilizing proven technology. This paper illustrates the technical and economical benefits of cogeneration in addition to demonstrating the fuel savings per unit of energy required. Specific examples show the feasibility and desirability of cogeneration systems for utility and industrial cases. Consideration of utility-industrial systems as well as industrial-industrial systems will be described in technical arrangement as well as including a discussion of financial approaches and ownership arrangements available to the parties involved. There is a considerable impetus developing for the utilization of coal as the energy source for the production of steam and electricity. In many cases, because of economics and site problems, the central cogeneration facility will be the best alternative for many users.

Utility Marketing Strategies and Pricing Trends (An Overview)
"Industries and utilities alike find themselves today in a very competitive environment. Industry finds that it must defend against threats to its markets from both domestic and foreign competitors. Likewise, utilities are challenged by industry and by neighboring utility companies to achieve new levels in customer service, reliability, and pricing. The two, industry and utility, are not antagonists, but are actually partners in the same venture--the industrial customer's costs are oftentimes tied closely to the price of electric power, and the utility's economic health depends upon the continued success of its customers. To work, a utility's marketing strategy and pricing arrangements must form a cohesive whole. Electric 'power rates must be able to recover a utility's costs and provide a sound fiscal footing for the utility, and yet still be attractive to industry and encourage the economic development of the region. However, lower rates are simply not the only answer in a sound marketing strategy. Rather than merely developing plans in accordance with the lowest feasible rates, it is reasonable for the utility to promote electrical efficiency and industrial productivity to ensure that electricity becomes a decreasing economic burden on industry. The utility and its industrial customers must work together as partners for the success of any marketing strategy. In this way, new arrangements may evolve which pave the way for industrial growth. I chair this tutorial having firsthand experience of the value to a utility of fostering trusting relationships with the industrial customers it serves. Through such relationships, TVA has been able to learn at an early date the needs of the customers it serves, and to do what it can as a utility to meet those needs. This tutorial panel consists of national experts from industry, utility, and consulting firms, each having direct experience in the important area of utility marketing, pricing, and customer relations.

Inventing the future of reliability: FERC's recent orders and the consolidation of reliability authority
The Energy Policy Act of 2005 established mandatory reliability standard enforcement under a system in which the Federal Energy Regulatory Commission and the Electric Reliability Organization would have their own spheres of responsibility and authority. Recent orders, however, reflect the Commission's frustration with the reliability standard drafting process and suggest that the Electric Reliability Organization's discretion is likely to receive less deference in the future.

The overall objective of the Advanced Turbine System (ATS) Phase 3 Cooperative Agreement between GE and the U.S. Department of Energy (DOE) is the development of a highly efficient, environmentally superior, and cost-competitive utility ATS for base-load utility-scale power generation, the GE 7H (60 Hz) combined cycle power system, and related 9H (50 Hz) common technology. The major effort will be expended on detail design. Validation of critical components and technologies will be performed, including: hot gas path component testing, sub-scale compressor testing, steam purity test trials, and rotational heat transfer confirmation testing. Processes will be developed to support the manufacture of the first system, which was to have been sited and operated in Phase 4 but will now be sited and operated commercially by GE. This change has resulted from DOE's request to GE for deletion of Phase 4 in favor of a restructured Phase 3 (as Phase 3R) to include full speed, no load (FSNL) testing of the 7H gas turbine. Technology enhancements that are not required for the first machine design but will be critical for future ATS advances in performance, reliability, and costs will be initiated. Long-term tests of materials to confirm design life predictions will continue. A schematic of the GE H machine is shown in Figure 1-1. Information specifically related to 9H production is presented for continuity in H program reporting, but lies outside the ATS program. This report summarizes work accomplished from 4Q98 through 3Q99. The most significant accomplishments are listed.

Load as a reliability resource in restructured electricity markets
Recent electricity price spikes demonstrate the value that demand-side responses could bring to a restructured US electricity system. This report considers how even a modest increase in demand elasticity could dramatically reduce these extremes in price volatility. The report provides a three-part assessment addressing the ability of customer's load to participate in competitive markets and the current and potential future role of customer loads as system reliability resources. The study begins by evaluating the extent to which customer loads might be able to provide electricity reliability or ancillary services and reviewing aspects of a large utility's direct load control program. The second phase of the assessment contains a survey of ways in which load has been used as a system reliability resource focusing on programs triggered by system conditions and a real-time price signal. It reviews the experience of: (1) the California ISO's Demand Relief and Participating Load programs; (2) Interruptible load programs in California; (3) the New England ISO's Load Management program; and (4) a ''mature'' program in New Zealand. The third phase of the assessment examines the status of the underlying metering, communication, and control technologies used to effect customer responses. The final section of the report provides a vision of how the future might look and uses it to outline a program of needed R&D to increase the role of customer loads as system reliability resources. Key elements of this research program include: addressing the needs of system operators, making effective use of load management assets, making use of new program design concepts, the design of end-use technologies, and benefiting from program experiences.

Reliability Estimates for Power Supplies
Failure rates for large power supplies at a fusion facility are critical knowledge needed to estimate availability of the facility or to set priorties for repairs and spare components. A study of the "failure to operate on demand" and "failure to continue to operate" failure rates has been performed for the large power supplies at DIII-D, which provide power to the magnet coils, the neutral beam injectors, the electron cyclotron heating systems, and the fast wave systems. When one of the power supplies fails to operate, the research program has to be either temporarily changed or halted. If one of the power supplies for the toroidal or ohmic heating coils fails, the operations have to be suspended or the research is continued at de-rated parameters until a repair is completed. If one of the power supplies used in the auxiliary plasma heating systems fails the research is often temporarily changed until a repair is completed. The power supplies are operated remotely and repairs are only performed when the power supplies are off line, so that failure of a power supply does not cause any risk to personnel. The DIII-D Trouble Report database was used to determine the number of power supply faults (over 1,700 reports), and tokamak annual operations data supplied the number of shots, operating times, and power supply usage for the DIII-D operating campaigns between mid-1987 and 2004. Where possible, these power supply failure rates from DIII-D will be compared to similar work that has been performed for the Joint European Torus equipment. These independent data sets support validation of the fusion-specific failure rate values.

Utility Battery Storage Systems Program plan: FY 1994--FY 1998
The Utility Battery Storage Systems Program, sponsored by the US Department of Energy (DOE), is addressing needed improvements so that the full benefits of these systems can be realized. A key element of the Program is the quantification of the benefits of batteries used in utility applications. The analyses of the applications and benefits are ongoing, but preliminary results indicate that the widespread introduction of battery storage by utilities could benefit the US economy by more than $26 billion by 2010 and create thousands of new jobs. Other critical elements of the DOE Program focus on improving the batteries, power electronics, and control subsystems and reducing their costs. These subsystems are then integrated and the systems undergo field evaluation. Finally, the most important element of the Program is the communication of the capabilities and benefits of battery systems to utility companies. Justifiably conservative, utilities must have proven, reliable equipment that is economical before they can adopt new technologies. While several utilities are leading the industry by demonstrating battery systems, a key task of the DOE program is to inform the entire industry of the value, characteristics, and availability of utility battery systems so that knowledgeable decisions can be made regarding future investments. This program plan for the DOE Utility Battery Storage Systems Program describes the technical and programmatic activities needed to bring about the widespread use of batteries by utilities. By following this plan, the DOE anticipates that many of the significant national benefits from battery storage will be achieved in the near future.
Energy efficiency and electric utilities
Twenty years have now elapsed since the energy crisis irrevocably changed world energy priorities. The energy crisis banished all apparitions of cheap and almost limitless energy and made the public keenly aware of its scarcity. The sharp rise in energy prices that followed the Arab oil embargo created strong market incentives to conserve energy. Most users have substantially improved the efficiency with which they use energy, although one might lament that the gains have not been larger. In contrast to the increased efficiency with which electricity and other forms of energy are used, electric utilities themselves have singularly failed to improve their heat efficiency in generating electricity. This failure can be attributed to regulation preventing market forces from creating incentive to improve efficiency.

Reliability and Functional Availability of HVAC Systems
This paper presents a model to calculate the reliability and availability of heating, ventilation and air conditioning systems. The reliability is expressed in the terms of reliability, maintainability and decision capability. These terms are a function of the mean time between failure, mean time to repair and decision time. The availability is expressed as an operational and functional availability of the systems. These terms are a function of both the technical and human characteristics to maintain the systems in correct operational state. The result is based on a large amount data from operational organisations, the compulsory inspection of ventilation systems and momentary and continuous measurements made in HVAC-systems.

Innovative Utility Pricing for Industry
The electric utility industry represents only one source of power available to industry. Although the monopolistic structure of the electric utility industry may convey a perception that an electric utility is unaffected by competition, this is an erroneous perception with regard to industry. Electric utilities face increased competition, both from other utilities and from industrial self-generation. The paper discusses competition for industrial customers and innovative pricing trends that have evolved nationally to meet the growing competition for industrial sales. Cogeneration activities and the emerging concepts of wheeling power are also discussed. Specifics of industry evaluation and reaction to utility pricing are presented. Also enumerated are examples of the response various utilities throughout the United States have made to the needs of their industrial customers through innovative rate design. Industry/utility cooperation can result in benefits to industry, to the electric utility and to all other ratepayers. This discussion includes examples of successful cooperation between industry and utilities.

Hawaii Utility Integration Initiatives to Enable Wind (Wind HUI) Final Technical Report
To advance the state and nation toward clean energy, Hawaii is pursuing an aggressive Renewable Portfolio Standard (RPS), 40% renewable generation and 30% energy efficiency and transportation initiatives by 2030. Additionally, with support from federal, state and industry leadership, the Hawaii Clean Energy Initiative (HCEI) is focused on reducing Hawaii's carbon footprint and global warming impacts. To keep pace with the policy momentum and changing industry technologies, the Hawaiian Electric Companies are proactively pursuing a number of potential system upgrade initiatives to better manage variable resources like wind, solar and demand-side and distributed generation alternatives (i.e. DSM, DG). As variable technologies will continue to play a significant role in powering the future grid, practical strategies for utility integration are needed. Hawaiian utilities are already contending with some of the highest penetrations of renewables in the nation in both large-scale and distributed technologies. With island grids supporting a diverse renewable generation portfolio at penetration levels surpassing 40%, the Hawaiian utilities experiences can offer unique perspective on practical integration strategies. Efforts pursued in this industry and federal collaborative project tackled challenging issues facing the electric power industry around the world. Based on interactions with a number of western utilities and building on decades of national and international renewable integration experiences, three priority initiatives were targeted by Hawaiian utilities to accelerate integration and management of variable renewables for the islands. The three initiatives included: Initiative 1: Enabling reliable, real-time wind forecasting for operations by improving short-term wind forecasting and ramp event modeling capabilities with local site, field monitoring; Initiative 2: Improving operators situational awareness to variable resources via real-time grid condition monitoring using PMU devices and enhanced grid analysis tools; and Initiative 3: Identifying grid automation and smart technology architecture retrofit/improvement opportunities following a systematic review approach, inclusive of increasing renewables and variable distributed generation. Each of the initiative was conducted in partnership with industry technology and equipment providers to facilitate utility deployment experiences inform decision making, assess supporting infrastructure cost considerations, showcase state of the technology, address integration hurdles with viable workarounds. For each initiative, a multi-phased approach was followed that included 1) investigative planning and review of existing state-of-the-art, 2) hands on deployment experiences and 3) process implementation considerations. Each phase of the approach allowed for mid-course corrections, process review and change to any equipment/devices to be used by the utilities. To help the island grids transform legacy infrastructure, the Wind HUI provided more systematic approaches and exposure with vendor/manufacturers, hand-on review and experience with the equipment not only from the initial planning stages but through to deployment and assessment of field performance of some of the new, remote sensing and high-resolution grid monitoring technologies. HELCO became one of the first utilities in the nation to install and operate a high resolution (WindNet) network of remote sensing devices such as radiometers and SODARs to enable a short-term ramp event forecasting capability. This utility-industry and federal government partnership produced new information on wind energy forecasting including new data additions to the NOAA MADIS database; addressed remote sensing technology performance and O&M (operations and maintenance) challenges; assessed legacy equipment compatibility issues and technology solutions; evaluated cyber-security concerns; and engaged in community outreach opportunities that will help guide Hawaii and the nation toward more reliable adoption of clean energy resources.

Public Utility Commission in the year 2000
This article is about What is and What ought to be as we look to the institution of public utility commission regulation at the turn of the century. To signal my own view at the outset, I find the prospects somewhat worrisome in light of the nature and direction of much of the response to real and imaginary changes in the regulated sectors. I surely do not call for standing in place, but I strongly believe we should leave the place standing. The following items are discernable trends that will shape the PUC at the turn-of-the century: (1) dichotomy of customers into core and noncore groups, (2) unbundling and new service offerings with a menu of prices, (3) relaxed regulation and increased reliance on market solutions instead of command and control, (4) increased use of market-based pricing and incentive ratemaking, (5) large users seeking lowest-cost generation and supply services, (6) shift from old regulatory bargains regarding exclusive territorial franchises and assured recovery of costs and investments, (7) utility diversification, (8) increasing business risk for utilities, amd (9) uncertainty as to continued utility attention to social goals and a changing obligation to serve. For each of these, the author focuses on: (1) changing missions and roles of the PUC, (2) the strategies for achieving them, and (3) the implementation requirements that operationalize the strategies.

The Schatz Energy Research Center (SERC) assisted the Yurok Tribe in investigating the feasibility of creating a permanent energy services program for the Tribe. The original purpose of the DOE grant that funded this project was to determine the feasibility of creating a full-blown Yurok Tribal electric utility to buy and sell electric power and own and maintain all electric power infrastructure on the Reservation. The original project consultant found this opportunity to be infeasible for the Tribe. When SERC took over as project consultant, we took a different approach. We explored opportunities for the Tribe to develop its own renewable energy resources for use on the Reservation and/or off-Reservation sales as a means of generating revenue for the Tribe. We also looked at ways the Tribe can provide energy services to its members and how to fund such efforts. We identified opportunities for the development of renewable energy resources and energy services on the Yurok Reservation that fall into five basic categories: � Demand-side management � This refers to efforts to reduce energy use through energy efficiency and conservation measures. � Off-grid, facility and household scale renewable energy systems � These systems can provide electricity to individual homes and Tribal facilities in areas of the Reservation that do not currently have access to the electric utility grid. � Village scale, micro-grid renewable energy systems - These are larger scale systems that can provide electricity to interconnected groups of homes and Tribal facilities in areas of the Reservation that do not have access to the conventional electric grid. This will require the development of miniature electric grids to serve these interconnected facilities. � Medium to large scale renewable energy development for sale to the grid � In areas where viable renewable energy resources exist and there is access to the conventional electric utility grid, these resources can be developed and sold to the wholesale electricity market. � Facility scale, net metered renewable energy systems � These are renewable energy systems that provide power to individual households or facilities that are connected to conventional electric utility grid.
Investigation of anti-islanding schemes for utility interconnection of distributed fuel cell powered generations
The rapid emergence of distributed fuel cell powered generations (DFPGs) operating in parallel with utility has brought a number of technical concerns as more DFPGs are connected to utility grid. One of the most challenging problems is known as islanding phenomenon. This situation occurs when a network is disconnected from utility grid and is energized by local DFPGs. It can possibly result in injury to utility personnel arriving to service isolated feeders, equipment damage, and system malfunction. In response to the concern, this dissertation aims to develop a robust anti-islanding algorithm for utility interconnection of DFPGs. In the first part, digital signal processor (DSP) controlled power electronic converters for utility interconnection of DFPGs are developed. Current control in a direct-quadrature (dq) synchronous frame is proposed. The real and reactive power is controlled by regulating inverter currents. The proposed digital current control in a synchronous frame significantly enhances the performance of DFPGs. In the second part, the robust anti-islanding algorithm for utility interconnection of a DFPG is developed. The power control algorithm is proposed based on analysis of a real and reactive power mismatch. It continuously perturbs (±5%) the reactive power supplied by the DFPG while monitoring the voltage and frequency. If islanding were to occur, a measurable frequency deviation would take place, upon which the real power of the DFPG is further reduced to 80%; a drop in voltage positively confirms islanding. This method is shown to be robust and reliable. In the third part, an improved anti-islanding algorithm for utility interconnection of multiple DFPGs is presented. The cross correlation method is proposed and implemented in conjunction with the power control algorithm. It calculates the cross correlation index of a rate of change of the frequency deviation and (±5%) the reactive power. If this index increases above 50%, the chance of islanding is high. The algorithm initiates (±10%) the reactive power and continues to calculate the correlation index. If the index exceeds 80%, islanding is now confirmed. The proposed method is robust and capable of detecting islanding in the presence of several DFPGs independently operating. Analysis, simulation and experimental results are presented and discussed.

Field Operations Program Chevrolet S-10 (Lead-Acid) Accelerated Reliability Testing - Final Report
This report summarizes the Accelerated Reliability testing of five lead-acid battery-equipped Chevrolet S-10 electric vehicles by the US Department of Energy's Field Operations Program and the Program's testing partners, Electric Transportation Applications (ETA) and Southern California Edison (SCE). ETA and SCE operated the S-10s with the goal of placing 25,000 miles on each vehicle within 1 year, providing an accelerated life-cycle analysis. The testing was performed according to established and published test procedures. The S-10s' average ranges were highest during summer months; changes in ambient temperature from night to day and from season-to-season impacted range by as much as 10 miles. Drivers also noted that excessive use of power during acceleration also had a dramatic effect on vehicle range. The spirited performance of the S-10s created a great temptation to inexperienced electric vehicle drivers to ''have a good time'' and to fully utilize the S-10's acceleration capability. The price of injudicious use of power is greatly reduced range and a long-term reduction in battery life. The range using full-power accelerations followed by rapid deceleration in city driving has been 20 miles or less.

An Integrative Approach to Reliability Analysis of an IEC 61850 Digital Substation
In recent years, reliability evaluation of substation automation systems has received a significant attention from the research community. With the advent of the concept of smart grid, there is a growing trend to integrate more computation and communication technology into power systems. This thesis focuses on the reliability evaluation of modern substation automation systems. Such systems include both physical devices (current carrying) such as lines, circuit breakers, and transformers, as well as cyber devices (Ethernet switches, intelligent electronic devices, and cables) and belong to a broader class of cyber-physical systems. We assume that the substation utilizes IEC 61850 standard, which is a dominant standard for substation automation. Focusing on IEC 61850 standard, we discuss the failure modes and analyze their effects on the system. We utilize reliability block diagrams for analyzing the reliability of substation components (bay units) and then use the state space approach to study the effects at the substation level. Case study is based on an actual IEC 61850 substation automation system, with different network topologies consideration concluded. Our analysis provides a starting point for evaluating the reliability of the substation and the effects of substation failures to the rest of the power system. By using the state space methods, the steady state probability of each failure effects were calculated in different bay units. These probabilities can be further used in the modeling of the composite power system to analyze the loss of load probabilities.

Reliable High Performance Peta- and Exa-Scale Computing
As supercomputers become larger and more powerful, they are growing increasingly complex. This is reflected both in the exponentially increasing numbers of components in HPC systems (LLNL is currently installing the 1.6 million core Sequoia system) as well as the wide variety of software and hardware components that a typical system includes. At this scale it becomes infeasible to make each component sufficiently reliable to prevent regular faults somewhere in the system or to account for all possible cross-component interactions. The resulting faults and instability cause HPC applications to crash, perform sub-optimally or even produce erroneous results. As supercomputers continue to approach Exascale performance and full system reliability becomes prohibitively expensive, we will require novel techniques to bridge the gap between the lower reliability provided by hardware systems and users unchanging need for consistent performance and reliable results. Previous research on HPC system reliability has developed various techniques for tolerating and detecting various types of faults. However, these techniques have seen very limited real applicability because of our poor understanding of how real systems are affected by complex faults such as soft fault-induced bit flips or performance degradations. Prior work on such techniques has had very limited practical utility because it has generally focused on analyzing the behavior of entire software/hardware systems both during normal operation and in the face of faults. Because such behaviors are extremely complex, such studies have only produced coarse behavioral models of limited sets of software/hardware system stacks. Since this provides little insight into the many different system stacks and applications used in practice, this work has had little real-world impact. My project addresses this problem by developing a modular methodology to analyze the behavior of applications and systems during both normal and faulty operation. By synthesizing models of individual components into a whole-system behavior models my work is making it possible to automatically understand the behavior of arbitrary real-world systems to enable them to tolerate a wide range of system faults. My project is following a multi-pronged research strategy. Section II discusses my work on modeling the behavior of existing applications and systems. Section II.A discusses resilience in the face of soft faults and Section II.B looks at techniques to tolerate performance faults. Finally Section III presents an alternative approach that studies how a system should be designed from the ground up to make resilience natural and easy.

Reliability-aware dynamic energy management in dependable embedded real-time systems
Recent studies show that, voltage scaling, which is an efficient energy management technique, has a direct and negative effect on system reliability because of the increased rate of transient faults (e.g., those induced by cosmic particles). In this work, we propose energy management schemes that explicitly take system reliability into consideration. The proposed reliability-aware energy management schemes dynamically schedule recoveries for tasks to be scaled down to recuperate the reliability loss due to energy management. Based on the amount of available slack, the application size and the fault rate changes, we analyze when it is profitable to reclaim the slack for energy savings without sacrificing system reliability. Checkpoint technique is further explored to efficiently use the slack. Analytical and simulation results show that, the proposed schemes can achieve comparable energy savings as ordinary energy management schemes while preserving system reliability. The ordinary energy management schemes that ignore the effects of voltage scaling on fault rate changes could lead to drastically decreased system reliability.

Culture Representation in Human Reliability Analysis
Understanding human-system response is critical to being able to plan and predict mission success in the modern battlespace. Commonly, human reliability analysis has been used to predict failures of human performance in complex, critical systems. However, most human reliability methods fail to take culture into account. This paper takes an easily understood state of the art human reliability analysis method and extends that method to account for the influence of culture, including acceptance of new technology, upon performance. The cultural parameters used to modify the human reliability analysis were determined from two standard industry approaches to cultural assessment: Hofstede�s (1991) cultural factors and Davis� (1989) technology acceptance model (TAM). The result is called the Culture Adjustment Method (CAM). An example is presented that (1) reviews human reliability assessment with and without cultural attributes for a Supervisory Control and Data Acquisition (SCADA) system attack, (2) demonstrates how country specific information can be used to increase the realism of HRA modeling, and (3) discusses the differences in human error probability estimates arising from cultural differences.

The Reliability Value of Storage in a Volatile Environment
This paper examines the value of storage in securing reliability of a system with uncertain supply and demand, and supply friction. The storage is frictionless as a supply source, but once used, it cannot be filled up instantaneously. The focus application is a power supply network in which the base supply and demand are assumed to match perfectly, while deviations from the base are modeled as random shocks with stochastic arrivals. Due to friction, the random surge shocks cannot be tracked by the main supply sources. Storage, when available, can be used to compensate, fully or partially, for the surge in demand or loss of supply. The problem of optimal utilization of storage with the objective of maximizing system reliability is formulated as minimization of the expected discounted cost of blackouts over an infinite horizon. It is shown that when the stage cost is linear in the size of the blackout, the optimal policy is myopic in the sense that all shocks are compensated by storage up to the available level...

Reliability based investigation of design factors
Second-moment probabilistic techniques are used to formulate structural resistances and loads and to derive reliability-based safety, load, and strength factors for design. Existing concepts of the second-moment reliability theory have been extended to the practical case of multiple load combinations. This development consistently includes the stochastic character of loads and the unpredictable nature of their combinations. For this purpose, a new technique for the evaluation of load combinations is presented, whereby the moments of the extreme of combined loads is obtained in terms of the moments of individual loads and parameters describing their random fluctuations in time. Reliability-based safety, load, and strength factors are derived in terms of the acceptable level of risk, the coefficients of variation of the loads and resistance, uncertainties associated with errors in modeling and estimation, and a set of parameters describing the stochastic nature of loads and their combinations.
Nuclear Power - Control, Reliability and Human Factors

Utilities are doing too much breaker maintenance
Many breaker failures occur after the breaker has been torn down for maintenance because some error was made in reassembling it. Utilities now can get a better understanding of circuit breaker reliability as the result of a worldwide survey conducted by the International Conference on Large High-Voltage Electric Systems (Cigre) of the reliability of circuit breakers 63 kV and above. The most significant finding is that the rate of major failures have dropped drastically with the introduction of modern SF[sub 6] breakers (from 1.58 to 0.67 per 100 breaker-years). But the rate of minor failures - such as gas leaks, which require maintenance and add to the operating cost - has increased by 30%. Incorrect maintenance causes far fewer failures in modern breakers, simply because they have to be torn down less frequently. Only 15% as many major failures and 77% as many minor failures can be attributed to incorrect maintenance. The failure to open or close on command are still the dominant major-failure modes of circuit breakers. 4 tabs.

This Energy & Environmental Research Center (EERC) Year 2 Biomass Utilization Final Technical Report summarizes multiple projects in biopower or bioenergy, transportation biofuels, and bioproducts. A prototype of a novel advanced power system, termed the high-temperature air furnace (HITAF), was tested for performance while converting biomass and coal blends to energy. Three biomass fuels--wood residue or hog fuel, corn stover, and switchgrass--and Wyoming subbituminous coal were acquired for combustion tests in the 3-million-Btu/hr system. Blend levels were 20% biomass--80% coal on a heat basis. Hog fuel was prepared for the upcoming combustion test by air-drying and processing through a hammer mill and screen. A K-Tron biomass feeder capable of operating in both gravimetric and volumetric modes was selected as the HITAF feed system. Two oxide dispersion-strengthened (ODS) alloys that would be used in the HITAF high-temperature heat exchanger were tested for slag corrosion rates. An alumina layer formed on one particular alloy, which was more corrosion-resistant than a chromia layer that formed on the other alloy. Research activities were completed in the development of an atmospheric pressure, fluidized-bed pyrolysis-type system called the controlled spontaneous reactor (CSR), which is used to process and condition biomass. Tree trimmings were physically and chemically altered by the CSR process, resulting in a fuel that was very suitable for feeding into a coal combustion or gasification system with little or no feed system modifications required. Experimental procedures were successful for producing hydrogen from biomass using the bacteria Thermotoga, a deep-ocean thermal vent organism. Analytical procedures for hydrogen were evaluated, a gas chromatography (GC) method was derived for measuring hydrogen yields, and adaptation culturing and protocols for mutagenesis were initiated to better develop strains that can use biomass cellulose. Fly ash derived from cofiring coal with waste paper, sunflower hulls, and wood waste showed a broad spectrum of chemical and physical characteristics, according to American Society for Testing and Materials (ASTM) C618 procedures. Higher-than-normal levels of magnesium, sodium, and potassium oxide were observed for the biomass-coal fly ash, which may impact utilization in cement replacement in concrete under ASTM requirements. Other niche markets for biomass-derived fly ash were explored. Research was conducted to develop/optimize a catalytic partial oxidation-based concept for a simple, low-cost fuel processor (reformer). Work progressed to evaluate the effects of temperature and denaturant on ethanol catalytic partial oxidation. A catalyst was isolated that had a yield of 24 mole percent, with catalyst coking limited to less than 15% over a period of 2 hours. In biodiesel research, conversion of vegetable oils to biodiesel using an alternative alkaline catalyst was demonstrated without the need for subsequent water washing. In work related to biorefinery technologies, a continuous-flow reactor was used to react ethanol with lactic acid prepared from an ammonium lactate concentrate produced in fermentations conducted at the EERC. Good yields of ester were obtained even though the concentration of lactic acid in the feed was low with respect to the amount of water present. Esterification gave lower yields of ester, owing to the lowered lactic acid content of the feed. All lactic acid fermentation from amylose hydrolysate test trials was completed. Management activities included a decision to extend several projects to December 31, 2003, because of delays in receiving biomass feedstocks for testing and acquisition of commercial matching funds. In strategic studies, methods for producing acetate esters for high-value fibers, fuel additives, solvents, and chemical intermediates were discussed with several commercial entities. Commercial industries have an interest in efficient biomass gasification designs but are waiting for economic incentives. Utility, biorefinery, pulp and paper, or o

National Utility Rate Database: Preprint
When modeling solar energy technologies and other distributed energy systems, using high-quality expansive electricity rates is essential. The National Renewable Energy Laboratory (NREL) developed a utility rate platform for entering, storing, updating, and accessing a large collection of utility rates from around the United States. This utility rate platform lives on the Open Energy Information (OpenEI) website, OpenEI.org, allowing the data to be programmatically accessed from a web browser, using an application programming interface (API). The semantic-based utility rate platform currently has record of 1,885 utility rates and covers over 85% of the electricity consumption in the United States.

The Impact of Protection System Failures on Power System Reliability Evaluation
The reliability of protection systems has emerged as an important topic because protection failures have critical influence on the reliability of power systems. The goal of this research is to develop novel approaches for modeling and analysis of the impact of protection system failures on power system reliability. It is shown that repairable and non-repairable assumptions make a remarkable difference in reliability modeling. A typical all-digital protection system architecture is modeled and numerically analyzed. If an all-digital protection system is indeed repairable but is modeled in a non-repairable manner for analysis, the calculated values of reliability indices could be grossly pessimistic. The smart grid is emerging with the penetration of information-age technologies and the development of the Special Protection System (SPS) will be greatly influenced. A conceptual all-digital SPS architecture is proposed for the future smart grid. Calculation of important reliability indices by the network reduction method and the Markov modeling method is illustrated in detail. Two different Markov models are proposed for reliability evaluation of the 2-out-of-3 voting gates structure in a generation rejection scheme. If the model with consideration of both detectable and undetectable logic gate failures is used as a benchmark, the simple model which only considers detectable failures will significantly overestimate the reliability of the 2-out-of-3 voting gates structure. The two types of protection failures, undesired-tripping mode and fail-to-operate mode are discussed. A complete Markov model for current-carrying components is established and its simplified form is then derived. The simplified model can appropriately describe the overall reliability situation of individual components under the circumstances of complex interactions between components due to protection failures. New concepts of the self-down state and the induced-down state are introduced and utilized to build up the composite unit model. Finally, a two-layer Markov model for power systems with protection failures is proposed. It can quantify the impact of protection failures on power system reliability. Using the developed methodology, we can see that the assumption of perfectly reliable protection can introduce errors in reliability evaluation of power systems.

PFBC Utility Demonstration Project
This report provides a summary of activities by American Electric Power Service Corporation during the first budget period of the PFBC Utility Demonstration Project. In April 1990, AEP signed a Cooperative Agreement with the US Department of Energy to repower the Philip Sporn Plant, Units 3 4 in New Haven, West Virginia, with a 330 KW PFBC plant. The purpose of the program was to demonstrate and verify PFBC in a full-scale commercial plant. The technical and cost baselines of the Cooperative Agreement were based on a preliminary engineering and design and a cost estimate developed by AEP subsequent to AEP's proposal submittal in May 1988, and prior to the signing of the Cooperative Agreement. The Statement of Work in the first budget period of the Cooperative Agreement included a task to develop a preliminary design and cost estimate for erecting a Greenfield plant and to conduct a comparison with the repowering option. The comparative assessment of the options concluded that erecting a Greenfield plant rather than repowering the existing Sporn Plant could be the technically and economically superior alternative. The Greenfield plant would have a capacity of 340 MW. The ten additional MW output is due to the ability to better match the steam cycle to the PFBC system with a new balance of plant design. In addition to this study, the conceptual design of the Sporn Repowering led to several items which warranted optimization studies with the goal to develop a more cost effective design.
Plasma control and utilization
A plasma is confined and heated by a microwave field resonant in a cavity excited in a combination of the TE and TM modes while responding to the resonant frequency of the cavity as the plasma dimensions change to maintain operation at resonance. The microwave field is elliptically or circularly polarized as to prevent the electromagnetic confining field from going to zero. A high Q chamber having superconductive walls is employed to minimize wall losses while providing for extraction of thermonuclear energy produced by fusion of nuclei in the plasma.

Alternative methods for achieving given power system reliability levels. Final report
This work examines the relative cost-effectiveness of competing electrical generating alternatives in contributing to the overall reliability level of a utility system. Three principal issues raised by Section 209 of the 1978 Public Utility Regulatory Policy Act (PURPA) are considered. They are: When there is a need for additional generating capacity, is it cost-effective to: (1) use small unit sizes rather than fewer large units of similar total megawatt capacity, (2) use intermittent and unconventional generating units in place of some conventional units, (3) use generation in decentral rather than central applications.

Industrial Load Shaping: A Utility Strategy to Deal with Competition
In recent years competition from various sources such as cogeneration and bypass has led many utilities to refocus attention on their large industrial customers. Industrial load shaping is a customized program involving cost-effective process modifications and operational changes which result in a restructuring of the electric load profile of individual manufacturing facilities. Both the customer and the utility should realize benefits from these changes. There are five generic load shaping categories: rescheduling operations, capacity additions, product storage, automation and flexible manufacturing and electrotechnologies. The customized nature of the program requires that the utility work with industry experts to help customers identify specific load shape opportunities. The remainder of this paper provides guidelines for utility planners interested in developing such a program. It begins with an overview of general objectives, technology alternatives, market evaluation and selection criteria, and program implementation and monitoring procedures. The paper concludes with two utility case studies.

Cogeneration: The Need for Utility-Industry Cooperation
Cogeneration is receiving increasing attention because of its potential for efficient utilization of energy. Many recent cogeneration studies, however, have concentrated on the benefits and costs of cogeneration to industry, giving little consideration to utility roles and perspectives. This paper provides an overview of a project sponsored by the Electric Power Research Institute to evaluate industrial cogeneration applications, taking into account utility interactions and impacts. Recent changes in federal legislation, particularly the enactment of the Public Utility Regulatory Policies Act (PURPA), have attempted to remove many of the institutional barriers which in the past made industry hesitant to invest in cogeneration. However, to implement the most attractive cogeneration systems industry must consider the changing economics of utility power generation. Also, despite the attractiveness of cogeneration, many industrial managers are reluctant to invest scarce capital in an area which they do not consider a natural extension of their business. At the same time, many utilities facing slower load growth and economic/environmental /institutional constraints on capacity expansion are willing to consider cogeneration as an option. Cogeneration projects can be highly complementary to the traditional utility business and possibly offer an attractive profit potential. Also, utilities can offer industry the needed expertise to implement and operate cogeneration systems. Considerable benefits may therefore be derived from cooperative cogeneration ventures among utilities and industrial firms. Many different organizational and financial arrangements can be structured, including third party financing. The, paper will briefly discuss the need for and benefits of cooperative efforts and provide illustrative examples of different institutional arrangements.

Balancing Economics and Reliability to Evaluate Planning Options under Competitive Environment
After the electric industry was restructured in the 1990s to provide open transmission access and introduce competition into wholesale electricity markets, the reliability of the transmission grid became dependent on a combination of assets provided by independent commercial developers and regulated electric utility companies with a statutory obligation to deliver safe, adequate service to retail customers. In a competitive environment, increasing network flexibility is desirable. In the most prevalent p...

During the last decade, wind power generation has seen rapid development. According to the U.S. Department of Energy, achieving 20 % wind power penetration in the U.S. by 2030 will require: (i) enhancement of the transmission infrastructure, (ii) improvement of reliability and operability of wind systems and (iii) increased U.S. manufacturing capacity of wind generation equipment. This research will concentrate on improvement of reliability and operability of wind energy conversion systems (WECSs). The increased penetration of wind energy into the grid imposes new operating conditions on power systems. This change requires development of an adequate reliability framework. This thesis proposes a framework for assessing WECS reliability in the face of external disturbances, e.g., grid faults and internal component faults. The framework is illustrated using a detailed model of type C WECS- doubly fed induction generator with corresponding deterministic and random variables in a simplified grid model. Fault parameters and performance requirements essential to

This study developed a probabilistic methodology for assessment of the reliability and security of electrical energy distribution networks. This included consideration of the future grid system, which will rely heavily on the existing digitally based communication infrastructure for monitoring and protection. Event tree and fault tree methods were utilized. The approach extensively modeled the types of faults that a grid could potentially experience, the response of the grid, and the specific design of the protection schemes. We demonstrated the methods by applying it to a small sub-section of a hypothetical grid based on an existing electrical grid system of a metropolitan area. The results showed that for a typical design that relies on communication network for protection, the communication network reliability could contribute significantly to the frequency of loss of electrical power. The reliability of the communication network could become a more important contributor to the electrical grid reliability as the utilization of the communication network significantly increases in the near future to support ''smart'' transmission and/or distributed generation.

Phase II -- Photovoltaics for Utility Scale Applications (PVUSA). Progress report
Photovoltaics for Utility Scale Applications (PVUSA) is a national public-private partnership that is assessing and demonstrating the viability of utility-scale (US) photovoltaic (PV) electric generation systems and recent developments in PV module technology. This report updates the project`s progress, reviews the status and performance of the various PV installations during 1994, summarizes key accomplishments and conclusions for the year, and outlines future work. The PVUSA project has five objectives. These are designed to narrow the gap between a large utility industry that is unfamiliar with PV and a small PV industry that is aware of a potentially large utility market but unfamiliar with how to meet its requirements. The objectives are: Evaluate the performance, reliability, and cost of promising PV modules and balance-of-system (BOS) components side by side at a single location; Assess PV system operation and maintenance in a utility setting; Compare US utilities hands-on experience in designing, procuring, and operating PV systems; and, Document and disseminate knowledge gained from the project.

Bridging Resilience Engineering and Human Reliability Analysis
There has been strong interest in the new and emerging field called resilience engineering. This field has been quick to align itself with many existing safety disciplines, but it has also distanced itself from the field of human reliability analysis. To date, the discussion has been somewhat one-sided, with much discussion about the new insights afforded by resilience engineering. This paper presents an attempt to address resilience engineering from the perspective of human reliability analysis (HRA). It is argued that HRA shares much in common with resilience engineering and that, in fact, it can help strengthen nascent ideas in resilience engineering. This paper seeks to clarify and ultimately refute the arguments that have served to divide HRA and resilience engineering.

Software reliability and dependability: a roadmap
Shifting the focus from software reliability to user-centred measures of dependability in complete software-based systems. Influencing design practice to facilitate dependability assessment. Propagating awareness of dependability issues and the use of existing, useful methods. Injecting some rigour in the use of process-related evidence for dependability assessment. Better understanding issues of diversity and variation as drivers of dependability. Bev Littlewood is founder-Director of the Centre for Software Reliability, and Professor of Software Engineering at City University, London. Prof Littlewood has worked for many years on problems associated with the modelling and evaluation of the dependability of software-based systems; he has published many papers in international journals and conference proceedings and has edited several books. Much of this work has been carried out in collaborative projects, including the successful EC-funded projects SHIP, PDCS, PDCS2, DeVa. He has been employed as a consultant to

Partially stabilized zirconia piston bowl reliability
The Weibull based ''Simplified Structural Ceramic Design Technique'' was used to calculate the reliability of a partially stabilized zirconia (PSZ) piston bowl design. The details of the method and a set of sample calculations are presented. Test results of the piston bowl showed cracks in regions which had a high calculated probability of failure. In addition cracks developed in a region of high compressive/shear stress. Since Weibull reliability analysis only uses tensile stresses this area did not have a high calculated probability of failure. Several hypotheses are presented for the mode of failure in this region. The simplified technique was used to predict what the necessary material properties would have to be for successful PSZ insert of the design shown.

Reliability Estimation for Double Containment Piping
Double walled or double containment piping is considered for use in the ITER international project and other next-generation fusion device designs to provide an extra barrier for tritium gas and other radioactive materials. The extra barrier improves confinement of these materials and enhances safety of the facility. This paper describes some of the design challenges in designing double containment piping systems. There is also a brief review of a few operating experiences of double walled piping used with hazardous chemicals in different industries. This paper recommends approaches for the reliability analyst to use to quantify leakage from a double containment piping system in conceptual and more advanced designs. The paper also cites quantitative data that can be used to support such reliability analyses.

Quantifying reliability uncertainty : a proof of concept.
This paper develops Classical and Bayesian methods for quantifying the uncertainty in reliability for a system of mixed series and parallel components for which both go/no-go and variables data are available. Classical methods focus on uncertainty due to sampling error. Bayesian methods can explore both sampling error and other knowledge-based uncertainties. To date, the reliability community has focused on qualitative statements about uncertainty because there was no consensus on how to quantify them. This paper provides a proof of concept that workable, meaningful quantification methods can be constructed. In addition, the application of the methods demonstrated that the results from the two fundamentally different approaches can be quite comparable. In both approaches, results are sensitive to the details of how one handles components for which no failures have been seen in relatively few tests.

Human Reliability Analysis for Design: Using Reliability Methods for Human Factors Issues
This paper reviews the application of human reliability analysis methods to human factors design issues. An application framework is sketched in which aspects of modeling typically found in human reliability analysis are used in a complementary fashion to the existing human factors phases of design and testing. The paper provides best achievable practices for design, testing, and modeling. Such best achievable practices may be used to evaluate and human system interface in the context of design safety certifications.

On the internet grouping for reliable multicasting
Current implementation of multicasting is using UDP protocol which is unreliable. There are many problems in reliable multicasting that make it difficult to implement. A study of the problems of reliable multicasting and an algorithm for reliable multicast protocol are proposed in this thesis. Unfairness when some of the receivers are faster than the others, the overhead at the sender because of managing all the group members and the problem of the traffic congestion at the sender because of the acknowledgments from each receiver are the problems that our proposed algorithm solved. Our proposed protocol is to divide the multicast group into different subgroups in a way that all members of the subgroup are related in speeds, location etc. In this way, we will make the sender send the same message with different speeds to different receiver subgroups. The sender will send as many times as the number of the subgroups. This solution has the advantage that fast receivers will not wait for slow receivers until they receive their message, which will improve the performance of fast receivers. To reduce the number of acknowledgments at the sender, we select from each subgroup a member that sends acknowledgment to the sender. In this way, only one acknowledgment from the subgroup is sent to the receiver rather than every member sending an acknowledgment to the sender, which solves the problem of many acknowledgments at the sender.

Perspectives on the future of the electric utility industry
This report offers perspectives on the future of the electric utility industry. These perspectives will be used in further research to assess the prospects for Integrated Resource Planning (IRP). The perspectives are developed first by examining economic, political and regulatory, societal, technological, and environmental trends that are (1) national and global in scope and (2) directly related to the electric utility industry. Major national and global trends include increasing global economic competition, increasing political and ethnic strife, rapidly changing technologies, and increasing worldwide concern about the environment. Major trends in the utility industry include increasing competition in generation; changing patterns of electricity demand; increasing use of information technology to control power systems; and increasing implementation of environmental controls. Ways in which the national and global trends may directly affect the utility industry are also explored. The trends are used to construct three global and national scenarios- ``business as usual,`` ``technotopia future,`` and ``fortress state`` -and three electric utility scenarios- ``frozen in headlights,`` ``megaelectric,`` and ``discomania.`` The scenarios are designed to be thought provoking descriptions of potential futures, not predictions of the future, although three key variables are identified that will have significant impacts on which future evolves-global climate change, utility technologies, and competition. While emphasis needs to be placed on understanding the electric utility scenarios, the interactions between the two sets of scenarios is also of interest.

Computer scientists at FE's NETL study a visualization of a power plant component. Traditionally the process of taking a new power plant system from the drawing board to a first-of-a-kind prototype has involved a series of progressively larger engineering test facilities and pilot plants, leading ultimately to a full-scale demonstration. The process can take over 20 years or more and cost billions of dollars. Because of the significant efforts by DOE in the design and construction of advanced energy systems, traditions have changed.

Hualapai Tribal Utility Development Project
The first phase of the Hualapai Tribal Utility Development Project (Project) studied the feasibility of establishing a tribally operated utility to provide electric service to tribal customers at Grand Canyon West (see objective 1 below). The project was successful in completing the analysis of the energy production from the solar power systems at Grand Canyon West and developing a financial model, based on rates to be charged to Grand Canyon West customers connected to the solar systems, that would provide sufficient revenue for a Tribal Utility Authority to operate and maintain those systems. The objective to establish a central power grid over which the TUA would have authority and responsibility had to be modified because the construction schedule of GCW facilities, specifically the new air terminal, did not match up with the construction schedule for the solar power system. Therefore, two distributed systems were constructed instead of one central system with a high voltage distribution network. The Hualapai Tribal Council has not taken the action necessary to establish the Tribal Utility Authority that could be responsible for the electric service at GCW. The creation of a Tribal Utility Authority (TUA) was the subject of the second objective of the project. The second phase of the project examined the feasibility and strategy for establishing a tribal utility to serve the remainder of the Hualapai Reservation and the feasibility of including wind energy from a tribal wind generator in the energy resource portfolio of the tribal utility (see objective 2 below). It is currently unknown when the Tribal Council will consider the implementation of the results of the study. Objective 1 - Develop the basic organizational structure and operational strategy for a tribally controlled utility to operate at the Tribe�s tourism enterprise district, Grand Canyon West. Coordinate the development of the Tribal Utility structure with the development of the Grand Canyon West Power Project construction of the power infrastructure at Grand Canyon West. Develop the maintenance and operations capacity necessary to support utility operations. Develop rates for customers on the Grand Canyon West �mini-grid� sufficient for the tribal utility to be self-sustaining. Establish an implementation strategy for tribal utility service at Grand Canyon West Objective 2 - Develop a strategy for tribal utility takeover of electric service on the Reservation. Perform a cost analysis of Reservation electrical service. Develop an implementation strategy for tribal takeover of Reservation electrical service. Examine options and costs associated with integration of the Tribe�s wind resources.
