Solar and Storage facility powers up in California
Clearway Energy Group has proudly announced the commencement of commercial operations at the Daggett Solar + Storage facility, which stands as California’s largest hybrid solar and battery storage installation.
Situated in proximity to the retired Coolwater gas-fired power plant, the Daggett project boasts an impressive capacity of 482 MW for solar energy and 280 MW for energy storage. It is recognized as one of the country’s most substantial operational solar + storage hybrid facilities.
Daggett Solar + Storage is anticipated to generate a sufficient amount of electricity to supply over 181,000 homes and is equipped to store and release clean energy during peak demand periods to enhance grid reliability.
The construction of this facility was carried out in collaboration with I.B.E.W. Local 477, thereby generating more than 500 union jobs throughout the project’s construction phase.

More about Daggett Solar and Storage
The batteries for this project were provided by the global energy storage integrator, Wärtsilä. The entire Daggett venture is being executed in three distinct stages. The ultimate phase, featuring a 113.5 MW battery storage component with a separate contract linked to an investment-grade utility offtaker, is set to achieve commercial operation status in 2025. This development will bring the project’s total battery capacity to 394 MW.
Throughout its operational phase, Daggett Solar + Storage is projected to contribute up to $18.5 million in local tax revenue and an annual expenditure of $5 million. The project will also sustain over a dozen full-time jobs onsite and will continue to provide support to local institutions such as the Silver Valley High School, Alternative Education Center, Silver Valley Fire Alliance, and the local Chambers of Commerce.
Daggett has contractual arrangements with six load-serving entities, including Clean Power Alliance, Constellation, East Bay Community Energy (soon to be rebranded as Ava Community Energy), MCE, Pacific Gas and Electric Company (PG&E), and Southern California Public Power Authority (SCPPA).
Notably, PG&E has inked 15-year contracts for 46 MW / 184 MWh from Daggett 2 and 15 MW / 60 MWh from Daggett 3, as reported by Energy-Storage.news.
