he world’s largest storage battery facility - equipped with about 210,000 modules and 3.3 million cells - has been delivered to North Hokkaido Wind Energy Transmission Corporation, a corporation represented by Tomomi Yoshimura and which has its head office in Wakkanai City, Hokkaido by GS Yuasa Corporation. This facility was ordered in 2018 and installed without incident over a 16-month period from July 2020 to November 2021. GS Yuasa reports that it is committed to the maintenance of this storage battery facility for the next 20 years.
The storage battery facility, with an output of 240 MW and a capacity of 720 MWh, is located at the Kita Toyotomi Substation of Northern Hokkaido Wind Power Transmission (Toyotomi-cho, Teshio-gun, Hokkaido). Linking with wind power generation equipment suppresses output fluctuations caused by weather changes, contributing to the stabilization of the system.
The storage battery facility is equipped with industrial lithium-ion batteries manufactured by GS Yuasa. In addition, the STARELINK service, a storage battery maintenance service that uses GS Yuasa’s proprietary remote monitoring technology and predictive and forecasting technology, constantly monitors the voltage of all cells of lithium-ion batteries and performs fault surveillance, thereby ensuring a high level of safety. In case of a failure, GS Yuasa can utilize its nationwide service network, one of the largest in the industry, to respond to customer requests.
A spokesman comments: "We will continue to contribute to the stabilization of electric power by expanding sales of lithium-ion battery storage facilities. In addition, by taking charge of system coordination, we will contribute to the further introduction of renewable energies toward achieving carbon neutrality by 2050."
