Tokugin Tomony Link Up, a subsidiary of The Tokushima Taisho Bank, is moving ahead with its first grid-scale battery energy storage project in Japan. The company is developing a 1.99MW/8.23MWh battery storage facility in Itano District, located in Tokushima Prefecture. The parent bank officially announced the plan on February 20, 2026, confirming that the project is scheduled to begin commercial operations around the summer of 2026.
The battery system will use three Mega Power 2700A units supplied by PowerX. Engineering, procurement, and construction (EPC) responsibilities have been assigned to GreenEnergy Plus, which will also manage operations and maintenance (O&M) after commissioning. The project’s aggregation services will be handled by Sustech, helping the system participate efficiently in electricity markets and grid balancing activities.
Tokugin Tomony Link Up was established in February 2025 as part of the bank’s broader strategy to support decarbonization in the region. The company focuses on developing renewable energy plants, battery storage systems, and sustainability-related services. Through this initiative, the bank aims to strengthen local clean energy infrastructure and contribute to Japan’s carbon reduction goals.
This development reflects a growing trend among regional banks in Japan to expand into the renewable energy and storage sector. Financial institutions are increasingly creating dedicated energy subsidiaries to invest in clean technologies and support regional power stability. Tokugin Tomony Link Up joins other similar efforts, including energy arms launched by San-in-Godo Bank and Higo Bank, which have also entered the grid-scale battery storage market.
With this project, The Tokushima Taisho Bank strengthens its role not only as a financial institution but also as an active participant in the transition toward a more sustainable and resilient energy system.
