RES Americas Stores Energy for PJM

April 2, 2014 By Linda Hardesty

RES Energy ManageRenewable Energy Systems Americas began operation of the company’s first energy storage system. RES Americas conceived, developed, and constructed the energy storage system, which it will own and operate in Sunbury, Ohio.

The system is comprised of a +/-4 MW (8MW total range)/ 2.6 MWh lithium battery that will provide a service called “frequency regulation” to PJM.

The project utilizes lithium iron phosphate, a variant of lithium battery chemistry, and consists of two containers that house batteries weighing about 20 tons each, as well as a third container that converts the direct current (DC) output to alternating current (AC) for the grid. The equipment was supplied by BYD America.

RES Americas anticipates delivering the company’s second 4 MW system in June 2014 in Ontario, Canada, for the grid operator IESO. The company is currently marketing additional fully-developed frequency regulation projects in PJM.
