Distribution microgrids can safely power some areas during a PSPS event


We continue improving our system to keep customers safe and reduce the impacts of Public Safety Power Shutoff (PSPS). This includes using distribution microgrids to power central community corridors.

What is a distribution microgrid?


Distribution microgrids can provide temporary power separate from the larger grid. Generators are staged at the microgrid or sent when it is safe to energize the area. These microgrids are used to power community resources during a PSPS outage, including:

  • Emergency and healthcare services
  • Gas stations
  • Schools
  • Grocery stores


During a PSPS, we determine if it is safe to use distribution microgrids in targeted areas that are:

  • Served by underground power lines
  • Outside of high fire-threat areas
  • Outside of the PSPS weather footprint
