GS Yuasa Battery Europe Ltd are proud to highlight a significant achievement by their parent company GS Yuasa who will supply a 50MWh lithium-ion battery storage system for the Tsunokobaru Power Storage Station in Japan. This project, commissioned by Chiyoda Corporation for Nijio Co., Ltd., a subsidiary of Tokyo Gas Co., Ltd., will greatly enhance renewable energy utilisation and grid stability.
The Tsunokobaru Power Storage Station, supported by the Sustainable Open Innovation Initiative (SII), will be equipped with GS Yuasa lithium-ion batteries installed in containerised energy storage systems (ESS). This setup was chosen for the exceptionally high performance and quality of GS Yuasa’s lithium-ion cells and modules, the system’s advanced safety features, and the reliable after-sales service provided by the battery manufacturer.
The system includes comprehensive safety monitoring of all cell voltages and module temperatures. Its fan-less modules reduce malfunctions and parts replacement needs. The modules are housed in fire prevention compliant cubicles and are resilient to severely cold climates. GS Yuasa ensures system reliability through constant voltage and failure monitoring. In the event of a malfunction, GS Yuasa’s service network provides prompt support.
Japan, much like Europe, has been experiencing a steady influx of renewable energy sources. However, this transition has presented challenges related to power grid stability due to the variable nature of renewable energy generation. These storage systems, a testament to GS Yuasa’s commitment to innovation, will play a pivotal role in harnessing the full potential of renewable energy sources by effectively managing the power supply-demand balance. By seamlessly recharging and discharging power to the grid, these systems ensure the stability and reliability of Japan’s power infrastructure.
As part of its ongoing commitment to energy stability, GS Yuasa will continue to expand the reach of its lithium-ion energy storage systems. This expansion aligns with the broader goal of enhancing grid adaptability and promoting the increased utilisation of renewable energy sources, thereby contributing to Japan’s pledge of achieving carbon neutrality by 2050.
