A ribbon-cutting ceremony was recently held in San Bernardino County, Calif., for the start of commercial operations at Daggett Solar + Storage, a project located adjacent to the decommissioned Coolwater gas-fired power plant.
The Daggett Solar+ Storage project encompasses 482 MW solar and 280 MW energy storage and is one of the largest operating solar and storage hybrid facilities in the country.
The full Daggett Solar + Storage complex is being completed in three stages. The final 113.5 MW battery storage portion, which is separately contracted with an investment-grade rated utility offtaker, is slated to reach commercial operations in 2025, bringing the project’s full battery capacity to 394 MW.
Daggett Solar + Storage is contracted with six load serving entities, including Clean Power Alliance, Constellation, East Bay Community Energy soon to be rebranded as Ava Community Energy, California community choice aggregator MCE, Pacific Gas and Electric Company and Southern California Public Power Authority.
“The Daggett 2 Project will provide SCPPA with its first bundled renewable energy and energy storage project to reach commercial operation by supplying 65MWac of solar capacity and a 33MWac/132MWh battery energy storage system to our growing renewable and energy storage resource mix,” commented Michael Webster, Executive Director of SCPPA.
“The project will help our Participating Members, the City of Cerritos and the City of Vernon Public Utilities, progress closer to meeting and exceeding their Clean Energy and Resource Adequacy goals,” he said.
The batteries were supplied by global energy storage integrator, Wärtsilä, noted project developer Clearway Energy Group.
