1. A system for managing and supplying power on an electric power grid that is constructed and configured for supplying and receiving power from a multiplicity of sources, where the power flows to a plurality of power consuming devices or is generated by a plurality of power generation and/or storage solutions that are energized, de-energized, and/or power-reduced by a plurality of controllable devices, the system comprising: a server comprising a command processor operable to receive or initiate power commands and issue power event messages responsive thereto for supplying power to the electric power grid by at least one power supply grid element; a coordinator constructed and configured in networked communication with the server, and operable for receiving, sending, storing, processing, and/or managing the power event messages for the server and for the plurality of power generation and storage solutions; wherein the power event messages are communicated over a network via the coordinator through an Internet Protocol (IP)-based messaging, synchronous time division multiplexed (TDM)-based messaging, or a proprietary-based messaging; wherein the power event messages include revenue grade metrology; a database for storing information relating to power consumed by the plurality of power consuming devices and power supplied by the plurality of power generation and/or storage solutions and generating an actual value of power to be reduced to each of the plurality of the power consuming devices and of power to be supplied by each of the plurality of power generation and/or storage solutions based on measurement and verification, wherein the actual value is a supply equivalent value accepted by a governing entity to provide power supply to the electric power grid; wherein generation of the actual value is also based on baselining and sampling; wherein the baselining provides a reference power usage point; wherein the sampling includes real-time or near-real-time power measurement sampling and wherein the sampling provides verification of power state and power consumption data for electricity consuming devices, reactive power, power factor, start-up current, duty cycles, voltage, and consumption forecasts; and wherein the system is operable for providing maintained or improved grid reliability and stability.
