Resilience Case Study: Borrego Springs Microgrid
In 2012, San Diego Gas & Electric (SDG&E) installed a microgrid in the desert town of Borrego Springs, California.
Previously, the town’s electricity was generated miles away, but when a thunderstorm knocked down the transmission line in 2013, the microgrid successfully directed power to critical zones.
SDG&E in 2015 expanded the microgrid and connected it with a nearby solar farm, enabling it to bring power to all of Borrego Springs during times of crisis.
Microgrid Costs & Benefits
Leadership & Replication
The US Department of Energy, the California Energy Commission, and the Pacific Northwest National Laboratory provided technical expertise.
In 2017, the California Energy Commission issued a request for proposals to fund microgrids in other California cities.
Numerous microgrid projects exist in other cities, including: New York, NY; Princeton, NJ; and Philadelphia, PA.
