LG Chem is to supply lithium-ion batteries for a 2MW energy storage system aimed at increasing Ohio’s grid reliability and stability.
The storage project will help regulate electric grid frequency for PJM, the transmission organisation that powers the eastern side of the 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 will provide the project’s advanced lithium-ion integrated operating system; Greensmith will provide intelligent energy storage control and analytics software, and system integration services.
Parker Hannifin will provide a 2-MW power conversion inverter.
The battery-based ESS, designed to enhance reliability and increase stability on the electric power grid, is expected to be operational by late 2015.
Duke Energy already operates a separate 2-MW storage system at Beckjord.
Duke Energy also operates a 36 MW battery-based energy storage and power management systems in Texas.
