Toshiba to Supply Lithium-ion Battery Energy Storage System for Frequency Regulation Project in the US

2218073_US_ESS[1]Toshiba Corp. has received an order to supply a large scale battery energy storage system (BESS) for a power frequency regulation project in Hamilton, Ohio. The project will be carried out by Sumitomo Corp., Sumitomo Corp. of Americas and Renewable Energy Systems Americas, a US renewable energy developer. Toshiba’s BESS, integrating an array of 6MW-2MWh SCiB lithium-ion batteries, will be delivered in November, and the system is scheduled to start operation in December.

Toshiba’s SCiB is a lithium-ion secondary battery, distinguished by its long-life and  performance; it charges and discharges efficiently in a wide range of temperatures, high and low. It has a long lifetime of more than 10,000 charge-discharge cycles, and operates with a high level of reliability and safety, including high resistance to external shock. The SCiB has found numerous applications, such as the power source for electric and hybrid vehicles.

The USA has seen the emergence of a power trading through a frequency regulation market as a mechanism for preventing instability in the power grid resulting from the feed-in of increasingly and widely used renewable energy sources, such as wind power and photovoltaic generation. Toshiba’s BESS delivers a rapid and fine-tuned response to frequency changes, and with the SCiB’s long life, it offers an optimized solution for long-term power regulation.

Toshiba is promoting BESS globally as an effective tool for ironing out frequency fluctuations and supporting stable power networks, and has supplied systems for projects in Japan and around the world.

Toshiba will continue to develop innovative solutions to support reliable electric power supply, and to expand its large-scale BESS business in the global market.
