California utility SDG&E brings online 180MWh of community-resiliency microgrids

San Diego Gas & Electric (SDG&E), one of California’s main investor-owned utilities (IOUs), has brought online a portfolio of four ‘advanced’ microgrids equipped with 180MWh of battery storage.

The self-contained energy systems are aimed at giving greater resilience to disruptions in electricity supply for four communities in the San Diego area of the US West Coast state, as well as enabling them to make greater use of local solar PV generation.

At 39MW output to their combined 180MWh energy capacity, the batteries’ average duration at the sites is around 4.6-hour, with each deployed at a different utility substation serving communities in Clairemont, Tierra Santa, Paradise, and Boulevard.

San Diego goes big on microgrids

The city of San Diego is about to join the microgrid movement.

The first of eight microgrid projects to be built at city facilities was unveiled Friday at the Southcrest Recreational Center in South County as part of a $5.5 million public-private partnership designed to reduce energy costs, cut greenhouse gas emissions and save taxpayers money.

“This microgrid specifically will allow the Southcrest Recreation Center to keep the lights on should there be an outage,” said Alyssa Muto, director of the city’s Sustainability and Mobility Department. “It would also allow the city to rely solely on renewable energy generated and stored here on site.”
