SDG&E adds energy storage facilities for grid reliability

San Diego Gas & Electric (SDG&E) has completed two additional utility-owned energy storage facilities totaling 171 MW, enough to power almost 130,000 homes for four hours.

The 131 MW Westside Canal project, located in Imperial Valley – home to a high concentration of solar, wind and geothermal generation facilities – is the largest storage asset in SDG&E’s energy storage portfolio; the 40 MW Fallbrook project, located in Northern San Diego County, is the second largest in its portfolio.

By the end of this year, SDG&E’s energy storage portfolio is expected to reach 345 MW of power capacity, sufficient to meet over 15% of its customers’ load on a typical day and 7% on a system peak day. These energy storage assets participate in the energy markets managed by the California Independent System Operator (CAISO), allowing CAISO to store and dispatch clean energy from the facilities to meet electricity demand as needed.
