Renewable Energy Systems Americas Inc. (RES Americas) has activated its first energy storage system, which is located in Sunbury, Ohio, just outside of Columbus.
RES Americas conceived, developed and constructed the energy storage system, which it will own and operate. The system is a +/-4 MW (8 MW total range)/ 2.6 MWh lithium battery that will provide frequency regulation to the PJM Interconnection, the largest power grid operator in North America.
The project uses 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.
The global market for energy storage is expected to grow rapidly in the coming years. Navigant Research estimates that worldwide revenue from advanced batteries for utility scale energy storage applications will grow from $164 million in 2014 to more than $2.5 billion in 2023. Frequency regulation represents a small fraction of the numerous services that energy storage can provide to the grid, according to RES Americas.
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.
