  • NARUC-NASEO Microgrids State Working Group Resource Repository
    Microgrids can provide reliable, resilient, affordable, and efficient electric power to critical infrastructure and electricity consumers. However, microgrid cost-benefit considerations and competing policy and regulatory goals present both opportunities and barriers to maximizing their value. Over the past several years, some State Energy Offices (SEOs) and Public Utility Commissions (PUCs) have explored and learned from various microgrid applications, but many information, research, investment, and policy and regulatory gaps remain. To address these issues and enable microgrids to deliver benefits to the public, NARUC and NASEO have formed the Microgrids State Working Group to share public- and private-sector best practices to advance beneficial microgrid development and take advantage of technical expertise from the U.S. Department of Energy (DOE).

    The Working Group is hosting facilitated discussions between SEOs and PUCs to explore microgrid technologies and applications, policy and regulatory frameworks, and financing models to understand the full range of benefits that microgrids can provide to owners / operators, ratepayers, and other stakeholders. A key objective of the Working Group is to highlight and draw lessons from existing microgrid projects. NARUC and NASEO are jointly leading this work in close collaboration with the DOE Office of Electricity and are relying on state input to guide this collaborative initiative.
