Smart grid goes to jail

Tools

An $11.7 million microgrid project designed and built by Chevron Energy Solutions will mean Santa Rita Jail in California's Alameda County can sustain power for daily operations and security if its connection to the grid is interrupted.

 

The jail's onsite power generation integrates with energy storage to ensure power is never lost. The microgrid also allows the jail to buy power from the utility during least expensive nonpeak hours and store it for use during the most expensive summer peak hours, which provides significant savings. In fact, the county anticipates it will save $100,000 per year in energy costs at the "mega jail" which covers 113 acres and houses as many as 4,000 inmates, making it the fifth largest such facility in the country.
