MI SB0477

Requires the Michigan Public Service Commission to issue orders within 270 days allowing the establishment and operation of microgrids within electric utility service territories

Defines "microgrid" as interconnected loads and distributed energy resources that can operate independently or connected to the main grid, with the ability to switch between grid-connected and island modes

Creates "community service power" as a new category of electricity distribution through microgrids that can cross property lines and public roads without being classified as a regulated electric utility

Prohibits standby rates from being charged for electricity imported by microgrids under 10 megawatts of electrical load, while ensuring standby tariff service remains available but not required

Requires uniform interconnection procedures for microgrids across all electric utilities following commission-promulgated standards
