Duke Energy, LG Chem and Greensmith have completed a 2-megawatt battery-based energy storage system designed to increase reliability and stability on the electric power grid.<\/p>\n
The fast-response system is now actively regulating electric grid frequency for PJM, the regional transmission organization that directs the flow of electricity for 61 million people in 13 states and the District of Columbia. Construction began in August 2015, at Duke Energy’s retired W.C. Beckjord coal-fired power plant in New Richmond, Ohio, and the system began operations on Nov. 17.<\/p>\n
“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. “This system is another step for Duke in the development of turnkey energy storage solutions that benefit customers and demonstrate the potential for future applications, such as large-scale integration of renewable energy onto the grid.”<\/p>\n
LG Chem delivered the project’s energy storage operating system, comprised of advanced lithium-ion batteries. Greensmith provided its latest GEMS energy storage software platform to manage the system’s performance for PJM frequency regulation, ensuring precise and synchronized response to signals dispatched every two seconds. Parker Hannifin provided a 2-MW power conversion inverter.<\/p>\n
The 2-MW project adds to Duke Energy’s installed base of commercially operating energy storage systems. With the completion of the new project, the company will operate a total of 4 MW of energy storage at Beckjord, where a separate 2-MW battery system already exists. Duke Energy also owns and operates a 36-MW energy storage system at its Notrees Windpower Project in Texas.<\/p>\n","protected":false},"excerpt":{"rendered":"
