Three companies have joined forces to turn an old US coal plant into a lithium-ion battery-based energy storage system in the state of Ohio.
Duke Energy, LG Chem and Greensmith have completed the 2MW ESS, which is designed to increase reliability and stability on the electric power grid in the District of Columbia, US.
Korean firm LG Chem supplied the project’s integrated operating system, which is comprised of advanced lithium-ion batteries.
Electric utilities firm Duke Energy already operates 4 MW of energy storage at Beckjord, where a separate 2-MW battery system already exists.
Phil Grigsby, Duke Energy’s senior vice president of Commercial Transmission, said the project demonstrated the potential for future applications, such as large-scale integration of renewable energy onto the grid.
US firm Greensmith provided its GEMS energy storage software platform to manage the system’s performance. US company Parker Hannifin provided a 2-MW power conversion inverter.
Construction began in August 2015 at Duke Energy’s retired W.C. Beckjord coal-fired power plant in New Richmond.
Duke Energy owns nearly 15 percent of the grid-connected, battery-based energy storage capacity in the US, according to independent research firm IHS Energy.
