S&C and Schneider Electric built the microgrid in six months at Oncor’s System Operating Services Facility (SOSF). The system is designed to seamlessly integrate energy storage and renewable energy resources with cutting-edge hardware and software to showcase how microgrids can enhance reliability for Oncor customers.

The grid-tied system consists of four interconnected microgrids and nine different distributed generation resources: two solar PV arrays, a microturbine, two energy storage units, and four generators. The system has a total peak capacity of 900 kilowatts, but could theoretically scale to meet just about any need.
