Designing and staging Community Microgrids for resilience
The Clean Coalition’s Community Microgrids are designed to provide indefinite, renewables-driven backup power to critical facilities. Our Community Microgrid Initiative will provide a standard methodology that any community can use to optimize and streamline the deployment of local renewable energy.
A Community Microgrid is a coordinated local grid area served by one or more distribution substations and supported by high penetrations of local renewables and other distributed energy resources (DER), such as energy storage and demand response. Community Microgrids represent a new approach for designing and operating the electric grid, relying heavily on DER to achieve a more sustainable, secure, and cost-effective energy system while providing indefinite, renewables-driven backup power for prioritized loads
Spanning 70 miles of California coastline — encompassing the cities of Goleta, Santa Barbara (including Montecito), and Carpinteria — this highly transmission-vulnerable, disaster-prone region can benefit greatly from the resilience provided by Community Microgrids.

Rather than continuing the slow process of evaluating local renewable energy projects one at a time, our Community Microgrid Initiative is creating a fast pathway to bring clean local energy online.
By modeling large areas of the distribution grid, we can efficiently identify greater distributed generation opportunities, allowing utilities and regulators to establish streamlined deployment plans. This systemwide approach enables large amounts of local renewables to come online in months rather than years.
The Clean Coalition is collaborating with electric utilities and technology firms to ensure that grid modeling software enhances visibility and management of energy at the distribution grid level. This advanced distribution grid modeling, which includes optimization analysis for both the location and mix of distributed energy resources, allows for a quick and accurate assessment of an individual substation’s potential capacity for local renewable energy. Utilities can then rapidly deploy local renewables in communities based on simplified integration scenarios, such as:
These scenarios will guide utilities and regulators to determine appropriate local capacity targets for renewable energy and establish pathways to meet an area’s specified goals.
The Clean Coalition is focusing on Community Microgrid configurations that incorporate combinations of various factors.
While deploying a true Community Microgrid requires utility cooperation, standalone microgrids are becoming more common around California and the US.
In addition to the Clean Coalition’s projects detailed above, we have compiled a list of some of the microgrids around the country, including in California.
