Renewable Energy Systems Americas Inc. (RES Americas), which develops and owns wind and solar projects in North America, has announced the operation of the company's first energy storage system.

RES Americas conceived, developed and constructed the energy storage system, and the company will also own and operate it. RES says the system, located in Sunbury, Ohio, features a +/-4 MW (8 MW total range) / 2.6 MWh lithium battery that will provide frequency regulation to grid operator PJM.

The project consists of two containers that house batteries weighing approximately 20 tons each, as well as a third container that converts the direct current output to alternating current for the grid. The equipment was supplied by BYD America.

"Leveraging our renewable energy, transmission and distribution construction experience, we are uniquely placed to excel in energy storage, whether as an IPP, or as an EPC for a utility owner,” comments Andy Oliver, RES Americas’ senior vice president of energy storage and technology.

RES Americas says it anticipates delivering the company's second 4 MW system in June 2014 in Ontario for the grid operator IESO. The company adds that it is currently marketing additional frequency-regulation projects in PJM.
