SolarCity signed a contract with Kaua’i Island Utility Cooperative (KIUC) to provide energy from a utility-scale solar project with battery storage during evening peak. The companies believe the project is the first utility-scale solar system in the United States to provide dispatchable solar energy.
Cost reductions in solar and battery storage have resulted in an economically viable utility-scale solar and battery storage project in Hawaii. When operational, the system should transform an intermittent solar resource into a firm, dispatchable power source. Solar and battery storage systems could become more common if technology costs continue to decline.
