Duke Energy Adds More Battery-Based Energy Storage Capacity
Duke Energy announced the completion of a 2-MW battery-based energy storage system that has been installed to increase power grid reliability and stability for the PJM regional transmission organization.
Installed at its retired W.C. Beckjord coal-fired power plant in New Richmond, Ohio, construction began in August, and the system was placed in operation on Nov. 17. The fast-response system will actively regulate electric grid frequency in the area.
“Locating the storage system at our retired coal plant allowed us to take advantage of the grid infrastructure already in place and repurpose the site for use with new, relevant technology,” said Phil Grigsby, Duke Energy’s senior vice president of Commercial Transmission.
The 2-MW project adds to Duke’s installed base of commercially operating energy storage systems. With the completion of the new project, the company operates a total of 4 MW of energy storage at Beckjord, and it also owns and operates a 36-MW energy storage system at its Notrees Windpower Project in Texas. All told, Duke is said to own nearly 15% of all the grid-connected, battery-based energy storage capacity in the U.S.
