The energy storage division of Japanese giant Toshiba has secured an order for a large-scale battery energy storage system (BESS) for a power frequency regulation project in the US state of Ohio.
Toshiba’s energy storage system, which includes a selection of 6MW-2MWh lithium-ion batteries, will be delivered in November with the system scheduled to start operation in Hamilton by year end.
The technology will be used by Sumitomo Corporation, Sumitomo Corporation of Americas and Renewable Energy Systems Americas, a US renewable energy developer, to support power trading through a frequency regulation market, a mechanism for preventing instability in the power grid resulting from the feed-in of renewable energy sources.
Global demand for energy storage
The deal follows Toshiba expanding its sales base for BESS technology in the US and globally.
In January 2015, the company teamed up with US utility Duke Energy in a pilot project for a BESS designed to regulate frequency and to increase grid stability.
In Europe, Toshiba has supplied BESS to projects in Italy, Spain, and the UK.
In Spain, Toshiba collaborated with Spain’s Gas Natural Fenosa in an on-site verification testing program for a transportable lithium-ion BESS, with the aim of achieving a reliable and stable distribution network.
In the UK, Toshiba supplied its SCiB battery for a 2MW energy storage system project led by the University of Sheffield.
Meanwhile, in Japan, Toshiba supplied a 40MW-20MWh BESS to Tohoku Electric Power Company, in what is the company's first large-scale project connected to Japan’s grid.
The Nishi-Sendai Substation Battery Energy Storage System Project was launched as a new measure against frequency changes caused by power output fluctuations.
Toshiba’s SCiB is a lithium-ion secondary battery that claims to have a lifetime of more than 10,000 charge-discharge cycles.
The SCiB is also being used in applications for electric and hybrid vehicles.
