DAIHEN Supplies Battery Energy Storage System Package to Takeo Energy Storage Plant

DAIHEN Corporation announces the delivery of a 'battery energy storage package' to the Takeo Energy Storage Plant (Takeo City, Saga Prefecture; hereinafter 'the plant'). The plant is being developed by Takeo Energy Storage G.K., a joint venture established through investments from multiple companies. JESCO Ecosystem Co., Ltd. handled the design and construction, and commercial operations began in November last year.

In recent years, with the rapid expansion of renewable energy adoption, compensating for fluctuations in power generation output and ensuring grid stability have become critical challenges.

▲Takeo Energy Storage Plant

One effective solution is the growing expectation for grid-connected battery storage systems that help balance electricity supply and demand. In particular, Kyushu, where renewable energy adoption is most advanced nationwide, experiences significant output fluctuations, and the deployment of grid-scale battery storage is expected to steadily increase.

DAIHEN provides a full suite of equipment required for grid-connected battery storage systems and has delivered solutions to over 30 projects across Japan, including in the Kyushu region. Moving forward, the company will strengthen sales of energy storage system-related products in the growing energy storage market, contributing to the optimal utilization of renewable energy and the realization of a decarbonized society.
