Duke Energy commissions 11 MW battery energy storage system project in North Carolina

Duke Energy has announced the opening of commercial operation for North Carolina's largest battery system in Onslow County, which complements the adjacent 13 MW solar facility based in Marine Corps Base Camp Lejeune, producing carbon-free energy since 2015. The battery's rated output is 11 MW with a capacity of 11 MWh, vastly expanding the state's battery storage capabilities. Both systems will operate independently or in unison, facilitating the efficient and reliable use of renewable energy resources.

The solar and battery systems' connection to the Duke Energy substation will allow them to provide power to all Duke Energy Progress customers, with further expansions to improve the resiliency of MCB Lejeune.

Duke Energy partnered with Black & Veatch construction entity OCI, which oversaw the engineering, procurement, and construction aspects of the project.

The battery utilizes a lithium iron phosphate chemistry and covers roughly 1 acre.
