Daiwa House Industry began construction of its first grid-scale battery storage facility, the 1.9MW/9.8MWh DREAM STORAGE Battery Fukuoka Kurate, on August 18, 2025, it announced on the same day.

According to the statement, the asset will be built at Daiwa House’s Fukuoka Factory in Kurate Town, on 530m2 of land previously occupied by tennis courts. It is expected to be commissioned around July 2026.

DREAM STORAGE Battery Fukuoka Kurate will serve as a pilot project allowing the company to gain expertise related to and assess costs and profitability of grid-scale storage. Daiwa House will handle engineering, procurement, and construction (EPC) in-house, with PowerX supplying four of its containerized Mega Power 2700A units.

The project received an approximately 140 million yen subsidy under METI’s FY2024 program for supporting BESS.

In an earlier report, The Nikkei said the company is concurrently considering multiple other projects, including assets not sited on its own premises.

Daiwa House and its wholly-owned subsidiary Daiwa Energy have been developing and operating solar and wind projects monetized both through the feed-in-tariff (FIT) scheme and, more recently, PPAs. The group has also offered power plant EPC services to third parties including Tokyo Gas and Sonnedix.
