URL More about SDG&E Borrego Springs Microgrid Demonstration Project: Community Energy Storage
The San Diego Gas and Electric (SDG&E) microgrid project integrates a U.S. Department of Energy (DOE) component - focused on utility-side applications, and a California Energy Commission (CEC) portion , which focuses on customer-side applications. Goals of the DOE portion include achieving a greater than 15 percent reduction in feeder peak load, exploring microgrid islanding, and improving system reliability. Borrego Substation, with a peak load of over 10 MW, was selected as the demonstration site since it provides a unique opportunity to explore microgrid islanding of an entire distribution feeder. The project involves integration of five technologies, including distributed energy resources (DER) and VAR management, feeder automation system technologies (FAST), advanced energy storage, an outage/distribution management system, and price-driven load management. The project team will also perform a cost/benefit analysis for full-scale deployment. SDG&E has installed two 25 kW/50 kWh Li-ion batteries and one 25 kW/25 kWh Li-ion battery on Circuit 170 at 12 kV. These units are operated independently and as a fleet.
