Japan’s Toshiba Corporation is to supply lithium-ion batteries for the country’s largest battery energy storage system (BESS).
The company’s batteries will be used in the 40MW-40MWh BESS, which aims to stabalise Japan’s grid using energy from renewable sources.
Toshiba SCiB™ lithium-ion secondary batteries will be integrated within the system at Japanese utility firm Tohoku Electric Power’s Minami-Soma Substation.
The BESS will store surplus electricity generated from renewable sources for use at times of high demand.
Construction of the BESS began on May 29 and the start of operation is scheduled for February 2016.
In 2014 Toshiba’s 40MW-class BESS was installed to regulate frequency changes caused by power output fluctuations at Tohoku Electric Power’s Nishi-Sendai Project.
Toshiba has supplied BESSs to projects in Italy, Spain, and a large-scale commercial BESS for frequency regulation project in the USA, scheduled to start operation this December.
Toshiba has also supplied SCiB™ for a 2MW energy storage system project led by the University of Sheffield in the UK.
