The California Energy Commission yesterday approved about $10 million in grants, one for a college microgrid in Sonoma County and the second for an airport microgrid in Humboldt.
The projects were selected earlier this year by the state to be considered for the grants as part of a competitive process for about $50 million in microgrid funds.
In Wednesday’s vote, the commission allotted the Sonoma County Junior College District about $5 million for a microgrid that will use photovoltaic solar power to meet 40 percent of the electricity needs at at Santa Rosa Junior College campus.
The college microgrid is expected to reduce peak load, optimize energy use, provide support to the surrounding grid. Highly resilient, the system will allow the campus to provide emergency services during power outages.
The commission also approved $5 million for the Humboldt State University Sponsored Programs Foundation, which is developing a community-scale renewable energy microgrid at the Redwood Coast-Humboldt County Airport.
The airport microgrid will demonstrate the first multi-customer, front-of-the-meter microgrid with renewable energy owned by a community choice aggregation and the microgrid circuit owned by an investor-owned utility. It is also Humboldt County’s second microgrid; the remote region is also site of the much-cited Blue Lake Rancheria microgrid, managed via an advanced control system by Siemens.
The community choice aggregation, a government-run energy program, will participate in California’s wholesale power market. At the same time, the microgrid will provide low-carbon resilience to a commercial airport and U.S. Coast Guard Air Station, which are critical emergency facilities in Humboldt County.
