Two projects, comprising 75 MWac / 300 MWh of energy storage, are being installed at Clearway Energy Group’s Mililani I Solar and Waiawa Solar Power facilities on the Island of Oahu in Hawaii.
Construction is expected to finalize in 2022.
The fifth project in the portfolio is a 147 MWac/588 MWh energy storage system that will be connected to the operating 192 MWac Rosamond Central solar PV facility in Kern County, California.
The energy storage system will increase the effectiveness of the solar facility by performing ancillary services, primarily solar shifting, for the California Independent System Operator.
Construction on the Rosamond Central project is expected to be completed in December 2023.
