GS Yuasa International Ltd. has confirmed receiving approval from Japan’s Ministry of Economy, Trade and Industry (METI) to build a stationary lithium-ion battery plant. Accordingly, the project, which will have a total project cost of ¥70.3 billion (US$453 million), has been certified under the Stable Supply Assurance Plan for a battery by the ministry.

The project will earn a subsidy of about ¥24.8 billion (US$159.90 million) from the Japanese government and will start production in October 2028. Its estimated production capacity is about 2GWh per year.

Role in Next-Gen Power Grid

Global demand for Energy Storage Systems (ESS) is rapidly increasing due to their indispensable role in grid stabilization. This is essential as renewable energy becomes a primary power source.

In addition, ESS deployment is expanding for purposes such as renewable energy self-consumption, peak shaving, and enhancing resilience against increasingly severe natural disasters.

Leveraging its extensive battery expertise cultivated over many years and proprietary battery life prediction technologies, GS Yuasa will contribute to the Japanese government’s goal of building a next-generation power grid with renewable energy as the primary power source.

This will be achieved by supplying stationary energy storage systems that achieve both high safety and sustainability for long-term operation, with all components, from lithium-ion cells to battery management systems, being manufactured in Japan.
