; (2) demonstrate— (A) secure integration and management of two or more energy resources, including distributed energy generation, combined heat and power, micro-grids, energy storage, electric vehicles, energy efficiency, demand response, and intelligent loads; and (B) secure integration and interoperability of communications and information technologies; and (3) be subject to the requirements of section 545(a) of the Energy Security and Independence Act of 2007 ( 42 U.S.C. 17155(a) ). 5. Micro-grid and hybrid micro-grid systems program (a) Definitions In this section: (1) Hybrid micro-grid system The term hybrid micro-grid system means a stand-alone electrical system that— (A) is comprised of conventional generation and at least 1 alternative energy resource; and (B) may use grid-scale energy storage. (2) Isolated community The term isolated community means a community that is powered by a stand-alone electric generation and distribution system without the economic and reliability benefits of connection to a regional electric grid. (3) Micro-grid system The term micro-grid system means a stand-alone electrical system that uses grid-scale energy storage. (4) Strategy The term strategy means the strategy developed pursuant to subsection (b)(2)(B). (b) Program (1) Establishment The Secretary shall establish a program to promote the development of— (A) hybrid micro-grid systems for isolated communities; and (B) micro-grid systems to increase the resilience of critical infrastructure. (2) Phases The program established under paragraph (1) shall be divided into the following phases: (A) Phase I, which shall consist of the development of a feasibility assessment for— (i) hybrid micro-grid systems in isolated communities
