Public Utility Commissions: Steps for Developing State Microgrid Regulations Microgrids are combinations of generation, storage, load management, and advanced controls, representing novel areas for state PUCs to regulate.
In addition to California, several other state microgrid programs and regulatory initiatives are in place. In June 2022, Colorado passed significant legislation that advances microgrid deployment in the state.
Typically, microgrid programs and regulations may originate within state legislation, which encourages or requires State Energy Offices and / or PUCs to initiate decision-making processes, to launch a microgrid grant program, or otherwise reduce barriers to microgrids.
When developing a state microgrid program, State Energy Offices can utilize their relationships with local governments, investor- and consumer-owned utilities, and the private sector.
