Japanese company Daiei Sangyo has signed a memorandum of understanding with Taiwan-based battery manufacturer Truewin Technology and Formosa Japan to jointly launch operations in grid-scale energy storage and artificial intelligence-based data centres. The agreement was announced in a joint statement on October 23.
The project aims to develop battery storage facilities with a total capacity of 800MWh across 100 sites in Japan. To support this initiative, Daiei Sangyo plans to invest ¥50bn ($325mn) over five years. This includes an initial allocation of ¥3bn ($19.5mn) to build its own storage facilities, expand development capabilities and secure inventory.
Objective: strengthen Daiei Sangyo’s role in the energy sector
Traditionally focused on demolition and recycling, Daiei Sangyo is shifting towards high-growth energy segments. According to the statement, the company plans to install batteries at its own factories, logistics hubs and other facilities to reduce electricity costs and improve infrastructure resilience. The operational knowledge gained will be used to offer similar services to businesses and local governments.
The company will also launch a solution called D-Package, a turnkey development and operation service for storage facilities. The goal is to gain a foothold in the emerging Virtual Power Plant (VPP) market and support the expansion of electricity trading platforms.
Joint deployment and pilot demonstrations planned
The three companies will establish several pilot demonstration sites to validate their technologies and commercial models. Truewin Technology, a battery solution provider, stated that these projects will help structure a long-term storage market in Japan.
Daiei Sangyo currently owns eight feed-in-tariff solar projects in Gunma Prefecture, with a combined capacity of 1.6MWAC. These projects form the company’s existing presence in the energy sector, but the new initiative marks a scale shift and a broader strategic ambition.
