This is a list of electricity-generating power stations in the U.S. state of Hawaii, sorted by type and name. In 2022, Hawaii had a total summer capacity of 2,906 MW through all of its power plants, and a net generation of 9,337 GWh.^[2] The utility-scale electrical energy generation mix in 2023 was 77% petroleum-derived fuels, 6.8% solar, 6.8% wind, 3.7% geothermal, 3% biomass, 0.9% hydroelectric, and 1.9% other.^[1] Hawaii's one geothermal plant, which previously supplied about 2% of the state's and 10% of the Big Island's electricity, was offline during 2019 to repair damage from the 2018 lower Puna eruption. The plant came back online in late 2020, slowly ramping up to its full operational level.^[3]

Small-scale distributed solar including customer-owned photovoltaic panels delivered an additional 1,409 GWh to the six separate electrical grids serving Hawaii's major islands in 2023.^[1] This was more than twice the amount generated by the state's utility-scale photovoltaic plants. In 2021, solar energy accounted for three-fifths of Hawaii's electricity generation by renewables. The state's renewable portfolio standard is the most ambitious in the U.S. at 30% of capacity by 2020, ramping to 100% by 2045. The large dependence on imported petroleum liquids contributes to Hawaii having the highest average retail electricity prices of any U.S. state.^[3]

Hawaii had no utility-scale power plants fueled by fissile material in 2019

^A Battery storage power stations stabilize an electrical grid against fluctuations in solar and wind generation for periods extending from less than a minute to as long as several hours.^[29]
