Osaka Gas and Daiwa Energy & Infrastructure signed a memorandum of understanding (MoU) to jointly develop and acquire renewable assets on September 30, 2025. Their first project under the tie-up is the acquisition of a 23MWAC/25MWDC FIT solar power plant in Kyoto City, Kyoto Prefecture.
According to the statement, the Kyoto power plant was commissioned in September 2017 and acquired through DD Solar LLC, in which each of the partners holds a 50% stake. METI data suggests the project was originally owned by Kyocera TCL Solar LLC, a joint venture between Kyocera and Tokyo Century.
The project was certified under the feed-in-tariff (FIT) scheme in FY2013, when 10kW and larger solar power plants were offered a fixed payment of 36 yen per kWh for 20 years. It was built by Sumitomo Mitsui Construction.
In addition to continuing joint acquisitions and development, Osaka Gas and Daiwa Energy & Infrastructure said they also plan to increase the value of the assets in their portfolio through battery storage retrofits and repowering.
Osaka Gas plans to grow its domestic and international portfolio of renewable assets to 5GW by FY2030 through both acquisitions and development. The Kyoto solar power plant brings its total to 3.79GW unadjusted for ownership share. Separately from the new partnership, the company has also acquired 40% stakes in multiple Sonnedix-led projects.
Daiwa Energy & Infrastructure has invested about 161 billion yen in solar, wind, storage, and other renewable projects in Japan and abroad as of the end of June 2025.
