About the project
- Client: California Energy Commission
Santa Rosa Junior College (SRJC) is currently developing a renewable energy generation based microgrid concept and design to address power reliability and resilience, so as to maintain operations during power outages, and to reduce greenhouse gas (GHG) emissions. Increasingly frequent wildfires pose multiple risks to the safety of SRJC students, staff, and surrounding community, and compromise the ability of the local utility company (Pacific Gas & Electric, PG&E) to meet campus energy needs. Therefore, the microgrid proposed herein has been designed and will be operated to meet resilience requirements, allowing SRJC to maintain business continuity through partial-day outages, as well as provide emergency services to students, staff, and the local community during longer outages. The proposed microgrid will also address the college’s environmental impact goals and related policy goals. The SRJC campus is currently reliant on electrical power from the PG&E grid, which uses approximately 15% fossil-derived energy sources, whereas the proposed microgrid would supply approximately 29% of the campus total electricity demand with 100% emissions-free PV solar energy. The proposed optimized microgrid generation and storage assets and operations schedule are detailed in this report. Further, recommendations are made regarding how utilities and community colleges can apply the approaches outlined in this study to overcome identified roadblocks to streamline the microgrid design process.
