The Campus

Santa Rosa Junior College (SRJC) is a 100+ acre campus in Santa Rosa, California, located in PG&E service territory. SRJC is part of the Sonoma County Junior College District (SCJCD), one of the largest single college districts in the United States. The campus has served as a community centerpiece for education, the arts, sports, and community cohesion for over 100 years. Located in a wildfire-prone area, the SRJC campus has the potential to serve as a vital resource to the surrounding community in the event of a planned or unplanned grid outage.

The campus owns and maintains the electrical infrastructure, a 12 kV feeder network, that serves 22 campus buildings and is connected to the PG&E grid at a single point of interconnection. Additionally, the campus is constructing three additional buildings over the next couple of years that will be integrated into the system.

Surrounding Community

SRJC sits within in a region of Northern California that been significantly impacted by wildfire events in the past five years. In October 2017, the community was devastated by the Sonoma Complex wildfires, among the most destructive in California history. The fires forced an estimated 100,000 residents to evacuate across the county and destroyed 3,043 houses just within the city of Santa Rosa – about 5% of the total homes in the city. In fall 2020, tragedy struck again when the Glass and Shady Fires struck the area. The need for resilient and reliable infrastructure is clear as wildfire events continue to impact the region year after year. The development of the SRJC campus microgrid will allow the campus to become a vital resource to the surrounding community in an emergency. The seamless islanding of the SRJC grid will allow it to keep its lights on in the case of an outage and continue to provide emergency services to students, faculty, and Santa Rosa residents.
