Duke Energy, LG Chem and Greensmith have installed a battery-based energy storage system in Ohio, designed to enhance reliability and increase stability on the electric power grid. The new 2-megawatt (MW) storage project will assist in regulating electric grid frequency for PJM, the transmission organization that powers much of the eastern U.S. The system will be built at Duke Energy's retired W.C. Beckjord coal-fired power plant in New Richmond, Ohio. LG Chem provided the Ohio project’s integrated operating system, comprised of advanced lithium-ion batteries. Greensmith provided intelligent energy storage control and analytics software, and system integration services. Parker Hannifin provided a 2-MW power conversion inverter.

With the addition of the new project, the company will operate a total of 4 MW of energy storage at Beckjord, where a separate 2-MW storage system already exists.
