Energy from a new paired solar and energy storage system being built in Hawaii will be dispatched at costs that are substantially below those of fossil fuels, which the islands currently depend heavily on. Kauai Island Electric Cooperative will pay 11 cents per kilowatt-hour for power from the system, a 28-megawatt solar array with 20-MW and 100-megawatt-hours of battery storage, 30 percent below what it signed a contract for solar-plus-storage system delivering power just two years ago. According to KIUC, the co-op paid 15 cents per kWh for fossil fuel-fired power in November. The new solar-storage project is expected to provide 11 percent of Kauai’s energy needs.
