Microgrids are a critical component to SDG&E’s efforts to keep customers energized during planned and unplanned outages, including Public Safety Power Shutoffs (PSPS). Microgrids are small electric grids that can operate independently from the larger grid. They often include a small network of users and a distributed energy resource, like solar panels and energy storage, that keeps the connected users energized.

Energy resiliency and reliability is a priority for SDG&E. Four microgrid sites are being developed and deployed at the Ramona Air Attack Base, Cameron Corners, Shelter Valley and Butterfield Ranch. The microgrids are designed to keep customers and critical facilities energized during PSPS and other outages. For example, the microgrid at the Ramona Air Attack Base, located in the northeastern part of San Diego County, serves CAL FIRE Air Support, United States Forest Service Air Support, and the local fire-retardant mixing station. These critical facilities support fire protection and coordination for the region.
