Exelon unit files EWG notice for 10-MW Clinton Battery project in Ohio

Clinton Battery Utility LLC, which has a nearly-commercial project in Ohio, on Oct. 7 filed with FERC a notice of self-certification of its status as an exempt wholesale generator.

The company is developing and will own and operate an approximately 10-MW (summer) energy storage facility located in Clinton County, Ohio. The facility consists of lithium ion batteries and associated interconnection facilities and is interconnected to the transmission system owned by Duke Energy Ohio and operated by PJM Interconnection. Commercial operation is expected to occur on Oct. 14, 2016.

The commission has previously determined that an energy storage facility can qualify as an “eligible facility” and its owner can qualify as an EWG when the facility is operated in such a manner that it will be engaged directly and exclusively in selling electric energy at wholesale, the notice said. Applicant is authorized to sell energy, capacity, and ancillary services at market-based rates and will provide frequency regulation service to PJM.

The contact information in the notice is for Exelon Corp. (NYSE:EXC).

Exelon Generation and Renewable Energy Systems (RES) had announced on April 19 the development of a 10-MW battery storage facility in Clinton County, Ohio. Exelon Generation is the storage facility owner and operator, and RES is the project developer and constructor. The said the battery storage units were expected to be fully operational by the end of the year.

Three semi-trailer sized units will be housed next to a substation to allow for easy interconnection to electrical lines within the PJM grid. The entire storage unit footprint is less than one-third of an acre.  The Clinton battery storage project will be powered by Samsung SDI‘s battery energy storage system, which uses lithium-ion batteries. Samsung SDI will provide more than 16,000 high-power batteries. The facility will also utilize five Parker Hannifin 2-MW power conversion systems, which use Parker’s two-phase refrigerant cooling solution. The conversion systems are self-contained and require no chilled water or external condenser, allowing for more efficient operation and longer life.

Exelon will have a total of approximately 20 MW of battery storage capacity in its portfolio upon project completion: 10 MW through the Clinton battery storage project and nearly 10 MW through Exelon’s competitive energy company, Constellation.
