Can Community Microgrids Fill the Gap in California’s Plans for 100% Renewable Energy?

The Goleta load pocket is a 70-mile stretch of Southern California coastline that includes the cities of Santa Barbara, Carpinteria and Goleta — combined population around 220,000 — all served by one 220-kV transmission line snaking its way over 40 miles of mountainous terrain.

With Water Supply Dwindling, Water District Plans Advanced Purification Project

Like many communities throughout California, Carpinteria faces sustained and historic drought conditions. By 2030, the Carpinteria Valley Water District estimates that dry years will come with a water deficit that could be as high as 1,550 acre feet—approximately 505 million gallons of water—enough to fill 775 Olympic-sized swimming pools, or serve the average daily use of 6,200 local households.

In response to the shortfall, CVWD proposes a $25 million project to take wastewater that has been cleaned, purify it and then inject it into the groundwater basin to be used for various needs, including potable drinking water.
