The US Navy plans to develop a utility-scale solar farm and energy storage system on the 863.6 hectare Pacific Missile Range Facility on the island of Kauai, Hawaii, according to a draft environmental assessment.
Solar PV paired with energy storage at scale could be provided to utilities at just US$0.10 per kilowatt hour, using advanced battery technology, one manufacturer has claimed.
The latest step in Hawaii’s clean energy evolution will be the deployment of a 20MW, five-hour duration battery energy storage system paired with 28MW of solar in Kaua’i, to match peak demand with generation.
The output of a 16MW solar farm in Puerto Rico will be tied to an Aquion ‘saltwater’ battery, in one of the few current trials of moving solar power produced in the daytime to be used at night.
SolarCity has chosen Tesla to supply a 52MWh utility-scale energy storage system, which will make the output of a solar farm in Hawaii dispatchable.
