Duke developing 2 MW storage facility for PJM frequency regulation
Duke, the largest electric utility in the country, is continuing to explore energy storage solutions and said it believes it owns almost 15% of the installed, grid-connected storage in the United States. The 2 MW project is aimed at enhancing reliability and grid stability across PJM.
LG Chem will create the project’s integrated operating system, while Greensmith will provide energy storage control and analytics software, and system integration services. A 2-MW power conversion inverter is being provided by Parker Hannifin.
“Fast-responding energy storage is recognized for the tremendous benefits it provides to grid operations, because it can instantaneously absorb excess energy from the grid or release energy,” Phil Grigsby, Duke Energy’s vice president of commercial transmission, said in a statement. “Delivering that power in seconds, as opposed to a power plant that could take 10 minutes or more to ramp up, is the unique value the battery system provides to grid operators.”
