; and (ii) micro-grid systems to enhance the resilience of critical infrastructure. (B) Phase II, which shall consist of the development of an implementation strategy, in accordance with paragraph (3), to promote the development of hybrid micro-grid systems for isolated communities, particularly for those communities exposed to extreme weather conditions and high energy costs, including electricity, space heating and cooling, and transportation. (C) Phase III, which shall be carried out in parallel with Phase II and consist of the development of an implementation strategy to promote the development of micro-grid systems that increase the resilience of critical infrastructure. (D) Phase IV, which shall consist of cost-shared demonstration projects, based upon the strategies developed under subparagraph (B) that include the development of physical and cybersecurity plans to take appropriate measures to protect and secure the electric grid. (E) Phase V, which shall establish a benefits analysis plan to help inform regulators, policymakers, and industry stakeholders about the affordability, environmental and resilience benefits associated with Phases II, III, and IV. (3) Requirements for strategy In developing the strategy under paragraph (2)(B), the Secretary shall consider— (A) establishing future targets for the economic displacement of conventional generation using hybrid micro-grid systems, including displacement of conventional generation used for electric power generation, heating and cooling, and transportation; (B) the potential for renewable resources, including wind, solar, and hydropower, to be integrated into a hybrid micro-grid system; (C) opportunities for improving the efficiency of existing hybrid micro-grid systems; (D) the capacity of the local workforce to operate, maintain, and repair a hybrid micro-grid system; (E) opportunities to develop the capacity of the local workforce to operate, maintain, and repair a hybrid micro-grid system
