GS Yuasa Corporation (Tokyo Stock Exchange: 6674) has delivered a lithium-ion battery storage system with a storage capacity of 4.2MWh to Kawara Town, Tagawa-gun, Fukuoka Prefecture as part of a joint project by NTT Anode Energy Corporation, Kyushu Electric Power Company Incorporated, and Mitsubishi Corporation. The system began operation in July 2023.

The joint project by the three companies aims to promote decarbonization and create new adjustment capacity through the effective use of output-controlled renewable electricity, and has been adopted by the Agency for Natural Resources and Energy as part of its fiscal 2021 supplementary budget "Project to Support the Introduction of Grid Storage Batteries, etc. to Accelerate the Introduction of Renewable Energy” subsidized project, which is an initiative to contribute to achieving carbon neutrality that is being promoted by Japan. This facility will also be used in a validation project to reduce the amount of solar power output curtailment, and to build a multi-use business model through trading in various electric power markets.

GS Yuasa will continue contributing to the field of power supply stabilization through expanding sales of its lithium-ion battery power storage systems. By helping to facilitate power grid adjustment capabilities, GS Yuasa is also contributing to further expansion of renewable energy use in support of Japan’s commitment to achieving carbon neutrality by 2050.

1. High level of safety ensured as voltage of all cells can be monitored and temperatures of all modules can be controlled
2. As the modules are fan-less, malfunctions are less likely to occur and the number of parts requiring replacement has been substantially reduced
3. Modules housed in fire prevention ordinance compliant cubicles in accordance with relevant laws and regulations
4. Able to withstand severely cold climatic conditions

In the event of a malfunction, GS Yuasa utilizes its nationwide service network (one of Japan’s largest) to promptly respond to customer needs.
