California’s first 100% renewable energy, front-of-the-meter, multi-customer microgrid is now fully operational, providing enhanced energy resilience for the California Redwood Coast-Humboldt County Airport and US Coast Guard Air Station.

The new microgrid was developed through a partnership between the County of Humboldt, Pacific Gas and Electric Company (PG&E), the Schatz Energy Research Center at California State Polytechnic University (Cal Poly Humboldt), Schweitzer Engineering Labs, the Redwood Coast Energy Authority, Tesla, Inc., The Energy Authority and TRC.

The RCAM includes a microgrid control system, with protection and isolation devices that interfaces directly with PG&E’s distribution control centre.
