Microgrid Services Tariff
(Docket No. 2018-0163)
A microgrid is a small-scale, local energy grid with control capability, which means it can disconnect from the traditional grid and operate autonomously. Microgrids facilitate the state’s achievement of its clean energy goals by allowing the integration of higher levels of renewable energy and distributed energy resources while improving customer electric reliability and resilience.
On May 21, 2021, the Commission approved Hawaiian Electric’s Microgrid Services Tariffs and concluded Phase 1 of the Docket. In Phase 2 of the proceeding, the Commission’s objective is to promote self-sufficiency and resilience among microgrid project operators and further streamline the Microgrid Services Tariffs. The docket’s Working Group continues to convene and provide updates and reports to the Commission.
