California’s San Pasqual Band of Mission Indians (SPBMI) has issued a request for proposals (RFP) that seeks design-build services for a hybrid microgrid that would supply electricity to essential buildings during utility outages.
Release of the RFP follows power shut offs to millions of Calfornians in recent weeks as utilities attempt to avert wildfires. A substantial number of wildfires in the state have been linked to utility transmission lines and equipment. As a result, microgrid developers are reporting an uptick in activity within the state.
San Pasqual seeks a grid-connected microgrid that will use solar, energy storage and liquid propane for six essential facilities at the tribe’s administration campus, part of a 2,656 acre community with 350 homes near San Diego.
The facilities total 41,898 square feet and include a wastewater treatment plant, a fire department, a housing and security building, and a preschool and an education building that each serve as community shelters.
The tribe already has two rooftop arrays, totalling 24 kW, that it plans to incorporate into the project. The RFP calls for expanding the solar so that it can serve 105% of the campus annual load, about 246,514 kWh. The project also includes charging for six electric vehicles.
