Sumitomo Corp. and Sumitomo Corporation of Americas announced Jan. 13 that they will commence operation of their innovative battery power storage system, Willey Battery Utility LLC, which has been constructed in Hamilton County, Ohio.
This facility will provide a reliable and stable supply-demand balancing service for the frequency regulation market operated by PJM Interconnection, the companies noted.
“As a developer of wind and solar power plants which are unavoidably intermittent generation sources, we think it is quite important that we also contribute to the stabilization of power grids through balancing services. Understanding that energy storage service is indispensable for further penetration of renewable energy, we will keep trying to expand our footprint in the energy-storage space, not only in frequency-regulation but also in other types of storage services,” said Nick Hagiwara, Director, Power and Infrastructure Group, Sumitomo Corporation of Americas.”
The company said it is becoming increasingly important to balance and manage the difference between actual and forecasted electricity demand, and stabilize the output of electricity to consumers. Sumitomo Corporation Group has piloted projects in Japan creating innovative battery storage systems from reused batteries of electric vehicles. These programs were piloted on the islands of Yumeshima, Osaka, Koshiki and Kagoshima in 2013 and 2014.
Willey Battery Utility LLC in August 2015 filed with the Federal Energy Regulatory Commission both a notice that it is an exempt wholesale generator and for approval of market-based rate authority. Willey Battery Utility (WBU) is a wholly owned subsidiary of Perennial Power Holdings Inc., an independent power company that acquires, develops, and operates electric power plants in North America. Perennial is owned 40% by Sumitomo Corp. and 60% by Sumitomo Corporation of Americas.
It said the project will have a 6-MW storage capacity, and will consist of three battery banks, three 2-MW bidirectional inverters, foundations, cables and wiring, switch gear, circuit breakers, transformers, and conductors. The facility will connect to a 34.5-kV line owned by Duke Energy Ohio, whose transmission facilities are located in the PJM region.
Energy will be collected from PJM’s transmission system through the Duke Energy Ohio line, and will be converted through the inverters at the facility to a form of energy that can be stored by the batteries. The stored energy may then be reconverted and delivered back to the PJM system through the same line. WBU will use the facility to provide frequency regulation service in the markets administered by PJM. The commission has recognized that such a battery storage facility qualifies as an “eligible facility,” and its owner as an EWG.
