On February 21, 2025, Tochigi-based renewable developer Sun Village signed a memorandum of understanding (MoU) with Chinese equipment manufacturer Sungrow’s Japan subsidiary, expressing its intent to procure about 500MWh of battery storage systems.
According to Sun Village’s statement, it plans to use Sungrow’s containerized PowerTitan and cabinet-type PowerStack systems. “[The systems are] have PACK, RACK, and PCS three-level overcurrent protection, fire safety design, and thermal runaway prevention function, and can be used in the primary balancing market,” said the statement.
Established in 2012, Sun Village has been developing and building low- and high-voltage solar power plants primarily in the northern Kanto region. Initially utilizing the feed-in-tariff (FIT) scheme, in recent years, Sun Village has also been growing its portfolio of non-FIT assets monetized through PPAs. The Japan Energy Hub PPA database shows it has, among others, been involved in a 1.5MW off-site deal with Skylark Holdings.
Aiming to capitalize on an increasing need for battery storage amid ongoing growth in non-dispatchable renewables, Sun Village also started developing grid-scale BESS projects. Earlier this month, it announced a partnership with Mitsubishi HC Capital Energy that plans to develop 100MW/400MWh of fully-merchant assets. Separately, it formed a partnership with HD Renewable Energy to jointly develop 13 2MW/8MWh projects in Tokyo and Chubu TSO areas.
Sun Village aims to develop 250 grid-scale BESS facilities totaling 500MW across Japan. It has not disclosed a timeline for achieving that goal.
