SDG&E has been rapidly expanding its battery energy storage and microgrid portfolio. Within our service territory, we have around 20 battery energy storage systems (BESS) and microgrid sites with 95 megawatts (MW) of utility-owned energy storage, plus another 200+ MW in development.
Typically, these battery systems and microgrids are installed on SDG&E-owned property; they are adjacent to our existing substation facilities or in critical locations where grid reliability and resiliency is needed most.
Microgrids are small-scale electric grids that can operate independent of or parallel to the larger regional grid and can keep critical community facilities powered during outages. Battery storage is an important part of every microgrid.
Battery storage works by absorbing electricity when it’s abundant on the power grid and sending excess power back to the grid when it’s most needed, such as during the evening after the sun sets and solar energy fades away.
