GE will supply Con Edison Development (CED) with an 8-MWh battery energy storage system in Central Valley, CA. The new storage solution will utilize GE's Mark VIe-based plant control system, Brilliance MW Inverters, and packaged lithium ion battery modules. The system will provide two MW of power over a four-hour period, and the deal includes delivery of a complete energy storage system, with associated long-term service agreements. The California-based installation will be CED's first energy storage project and will serve as a learning tool for optimizing and operating energy storage facilities in the future. The site is expected to be operational in the next six to nine months.
