SDG&E Adds Second San Diego Energy Storage Facility

San Diego Gas & Electric (SDG&E) announced the completion of a second energy storage project in the City of San Diego. 

The new 20MW/80MWh facility can meet the energy needs of about 13,000 homes for up to four hours.

“Investing in advanced technologies like energy storage is critical to advancing our state’s and region’s aggressive climate goals, including getting to net zero greenhouse gas emissions, with the added benefit of building a more resilient energy grid,” said SDG&E CEO Caroline Winn in a statement. “Project by project, step by step, we are making progress toward a cleaner, safer and more reliable energy future.”

The Kearny facility began commercial operation this month and will also be available for dispatch by CAISO. By year-end, SDG&E expects to have 145 MW of owned storage connected to the regional grid. 

The facility consists of lithium-ion phosphate batteries, which feature a chemistry that is more durable. The batteries are housed in special storage cubes that bring additional safety benefits such as temperature sensors and fire retardants. The Kearny facility is one of several SDG&E projects that will help California reach its goal of 100% carbon-free electricity, while also bolstering grid reliability during the summer.
