SDG&E awards energy storage contract to Mitsubishi Power

San Diego Gas and Electric (SDG&E) has tapped Mitsubishi Power to supply its battery energy storage solution for its Pala-Gomez Creek Energy Storage Project in Pala, Calif.

The 10 megawatt (MW)/60 megawatt-hour (MWh) battery energy storage solution will add capacity to help meet high energy demand, support grid reliability, and operational flexibility. The company’s Emerald storage solution will also maximize the use of renewable energy and help prevent outages during peak demand.

“SDG&E is committed to achieving net-zero greenhouse gas emissions by 2045. We are increasing our portfolio of energy storage assets to reach this goal. These assets enhance grid reliability and operational flexibility while maximizing our use of abundant renewable energy sources in California,” Fernando Valero, director, Advanced Clean Technology at SDG&E, said.

This is Mitsubishi Power’s eighth project in California, bringing total capacity to 280 MW/1,140 MWh of storage.

“As more and more renewables come online during the energy transition, BESS solutions are essential to support a reliable and stable grid. We look forward to providing SDG&E with our BESS solution to add capacity, energy, and ancillary services to California’s grid. Mitsubishi Power’s Emerald storage solutions are enabling a smarter and more resilient energy future for our customers in California and around the globe,” Tom Cornell, senior vice president, Energy Storage Solutions, Mitsubishi Power Americas, said.

The project will repower an existing energy storage site, employing Mitsubishi Power’s Emerald Integrated Plant Controller. The Mitsubishi Power Emerald Integrated Plant Controller complies with North American Electric Reliability Corporation’s critical infrastructure protection standards and meets the highest security certification in the energy storage industry.
