X-Elio sold the 9.99MWAC/14.4MWDC Funaki Solar Power Plant in Ube City, Yamaguchi Prefecture, to Sun Trinity, the company announced on August 18, 2026.
According to the statement, the asset, which was built on a former golf course, generates over 17GWh per year and supplies Amazon under a long-term PPA. Further details about the transaction were not disclosed.
Japan Energy Hub first reported the transfer in July 2026, when National Tax Agency records showed that the project’s special purpose company (SPC), X-Elio 19 LLC, was renamed to Sun Trinity 11 LLC and its registered address moved to the buyer’s office on June 24, 2026.
METI and OCCTO data show the project was certified under the feed-in-premium (FIP) scheme in January 2023, after the SPC secured a 9.85-yen-per-kWh contract in the 12th (FY2022’s first) solar auction. X-Elio commissioned the asset and launched the PPA in mid-2025, with ENGIE providing balancing services.
The developer has a pipeline of an additional 494MW of solar and grid-scale battery storage in Japan, including two extra high-voltage Hokkaido solar projects awarded FIP contracts in the 27th (FY2025’s fourth) auction. Funaki Solar Power Plant was the last to be divested among the 393MW of power plants that X-Elio completed in the country to date.
Sun Trinity was established in 2022 as a 60:40 joint venture between Sumitomo Corporation’s wholly-owned Power Frontier Holdings and Shikoku Electric Power, and targets developing and acquiring over 1GW of renewable capacity. The company has disclosed several PPAs, including a 20MWAC/40MWDC offsite deal with Hankyu and an approximately 14.9MW onsite solar carport rollout with Aeon Mall.
