Clearway Energy Group announced it has reached commercial operations at Daggett Solar + Storage, California’s largest hybrid solar and battery storage facility.

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.

Daggett Solar + Storage will generate enough electricity to power more than 181,000 homes and will be able to store and deploy clean power during periods of peak demand to support grid reliability.

Construction of Daggett Solar + Storage was completed in partnership with I.B.E.W. Local 477, creating over 500 union jobs during project construction.

The batteries were supplied by global energy storage integrator, Wärtsilä.

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 will generate up to $18.5 million in local tax revenue and $5 million in spending annually during operations. The project will sustain over a dozen onsite full-time jobs and will continue to support local institutions such as the Silver Valley High School and Alternative Education Center, the Silver Valley Fire Alliance, and the local Chambers of Commerce.

Daggett Solar + Storage is contracted with six load-serving entities, including Clean Power Alliance, Constellation, East Bay Community Energy (EBCE) soon to be rebranded as Ava Community Energy, MCE, Pacific Gas and Electric Company (PG&E), and Southern California Public Power Authority (SCPPA).

PG&E signed 15-year contracts for 46MW / 184MWh from Daggett 2 and 15MW / 60MWh from Daggett 3, Energy-Storage.news reported.
