Duke Energy to build energy storage system in Ohio

Duke Energy will build a battery-based energy storage system in Ohio to enhance reliability and increase stability on the electric power grid, company officials announced Tuesday.

Duke Energy will build the system in partnership with LG Chem and Greensmith at its retired W.C. Beckjord coal-fired power plant in New Richmond, Ohio. The system is expected to be operational by late 2015.

Duke Energy, the nation’s largest electric utility, currently owns 15 percent of the grid connected, battery-based energy storage capacity in the U.S. according to independent research firm IHS Energy.

The new 2-megawatt storage project will assist in regulating electric grid frequency for PJM Interconnection, the transmission organization that powers much of the eastern U.S., including Ohio.

Dayton Power & Light operates a 40-megawatt battery-based energy storage system at the Tait generating station in Moraine.

Charlotte, N.C.-based Duke Energy has 1.3 million customers in Ohio and Kentucky.
