Hawaii electricity market
Regulated state with the highest electricity rates in the United States, driven by per-island isolated grids, dependence on imported petroleum for generation, and the cost of operating multiple small power plants. Hawaiian Electric (HECO) serves Oahu, Hawaii Electric Light serves the Big Island, and Maui Electric serves Maui, Lanai, and Molokai; Kauai is served by the Kauai Island Utility Cooperative.
Where Hawaii residents save
Hawaii has the most economic residential solar in the US (under-6-year typical payback) because retail rates are so high. The state targets 100% renewable electricity by 2045 under HRS 269-92. The Hawaii Energy program offers rebates for heat-pump water heaters, LED retrofit, and AC efficiency.
