Exelon (NYSE:EXC) and Renewable Energy Systems (RES) said April 18 they are developing 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.
RES, a leader in the energy storage industry, will begin construction during the second quarter of 2016, with the battery storage units 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. Construction is expected to be completed by the fall of 2016.
The monitoring, dispatch and control of the system will be handled by the RESolve energy platform, a proprietary technology developed by RES. RESolve will manage the system to maximize revenue and minimize battery degradation.
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
“Having constructed over 70 MW of energy storage projects with 140 MW of operational range throughout North America, RES is excited to work with Exelon to provide frequency regulation service to PJM,” said Matthew Krivos, director, Energy Storage of RES. “We look forward to continuing to provide energy solutions to ensure longstanding benefits to the ever changing grid.”
Exelon Generation and RES closed the transaction on Feb. 1. This is the second joint project between the companies. In January, Exelon Generation and RES announced the 198 MW Bluestem Wind Project in Beaver County, Oklahoma, with a power purchase agreement executed with Google. RES will construct the Bluestem project for Exelon Generation this year. This is RES’ 10th energy storage project in North America and first utilizing Samsung SDI batteries.
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.
