SDG&E to Add Four Microgrids with Energy Storage to Further Boost Summer Grid Reliability and Advance Clean Energy Goals | Company



Four microgrids equipped with energy storage will be added to the San Diego area to help the state meet high energy demand, especially during hot summer days and during evening peak hours after the dissipation of solar energy. These small-scale networks that can operate independently or alongside the larger regional network will also help keep critical community facilities powered up during unplanned outages.

San Diego Gas & Electric (SDG&E) yesterday received approval from the California Public Utilities Commission to build these projects, which will add a total of approximately 39 megawatts (MW) / 180 megawatt hours (MWh) of storage capacity in four sub – company stations.

“These clean energy projects will help our region become more resilient to the impacts of our deteriorating climate,” said SDG&E Vice President, Energy Innovation Miguel Romero. “They will send clean power to the grid when needed and keep critical facilities like schools, cold zones and fire stations powered in an emergency.”

The projects come from Declaration by Governor Newsom of a State Emergency published last summer, which outlines California’s energy needs in the face of growing climate challenges. The four new projects, which are expected to be completed in the summer of 2023, are the latest in a series of energy storage investments by SDG&E, including the opening of Top Gun, a 30MW facility, in June. 2021 and Kearny Energy Storage, a 20 MW facility. , in March 2022.

Battery storage works by capturing renewable resources such as wind and sun when they are abundant during the day, then returning that energy to the grid when needed. As with other SDG&E-owned storage projects, these facilities will be connected to the state energy market so that the California Independent System Operator (CAISO) can allocate these resources as needed to balance supply and demand. energy across the state.

Below are brief descriptions of each of the projects.

  • The Clairemont Substation Microgrid will have the capacity to power the Balboa Branch Library/Chill Zone, Fire Station 36, and local schools such as Lafayette Elementary and Sequoia Elementary, Intermediate Innovation and CPMA and Madison High School.
  • The Boulevard Substation Microgrid will have the capacity to power the San Diego County Sheriff’s Department, Fire Station 47, Campo Reserve Fire Station, Cal Fire White Star Station, Office Campo Tribal, Campo Kumeyaay Nation Medical Centre, South India Health Council Campo Clinic, Boulevard Border Patrol Post and Boulevard Post Office
  • The Paradise Substation Microgrid will have the capacity to power Fire Stations 51 and 32, the Southeast Division Police Department and Bell Middle School, as well as Freese, Boone and Fulton Elementary Schools.
  • The Elliott Substation Microgrid will have the capacity to power Fire Station 39, Tierrasanta Public Library/Cold Zone, Tierrasanta Medical Center, Jean Farb Middle School, High School Canyon Hills and Tierrasanta and Kumeyaay Elementary Schools.
