Sumitomo Invests in U.S. Power Storage; Toshiba Supplies Battery

Sumitomo Corp. is investing in the U.S. power storage business with a system supplied by Toshiba Corp. to adjust demand and supply.

Sumitomo has acquired Willey Battery Utility from Renewable Energy Systems Americas, part of the RES Group, the Japanese company said in a statement Monday. Financial terms weren’t disclosed.

Toshiba will supply a storage system with a maximum output of 6 megawatts, providing a supply-demand balancing service for the frequency regulation market operated by PJM Interconnection LLC, Sumitomo said. PJM is an operator of power grids in 13 states in the northeastern U.S., according to the statement.

Construction will begin in Hamilton County, Ohio, in April and operations will begin in December, Sumitomo said. Toshiba will deliver and maintain the storage system; supplementary machinery will be supplied and installed by RES.
