ENEOS Renewable Energy partners with Marubeni to develop 10MW of low-voltage solar in Kansai by FY2027
November 12, 2025 – Japan
ENEOS Renewable Energy has signed a framework agreement with Marubeni Corporation to acquire 100 low-voltage solar power plants totaling 10MWDC in the Kansai Transmission System Operator (TSO) area by the end of fiscal year 2027, the company announced on November 11, 2025.
Under the agreement, Marubeni will be responsible for developing and constructing the solar assets, which will then be transferred to ENEOS Renewable Energy upon completion. Construction of the first batch of projects is expected to begin later this year, and both companies stated their intention to expand cooperation in the future as part of a broader renewable energy partnership.
Focusing on distributed solar opportunities
ENEOS Renewable Energy plans to sell the electricity output from these solar plants through corporate power purchase agreements (PPAs) but did not disclose whether it has already secured any offtakers.
Prior to this deal, ENEOS Renewable Energy had signed similar agreements with:
-
GreenEnergy Plus for 5MW of low-voltage solar projects in the Chubu region, and
-
H.E Energy for another 5MW in Tohoku.
In addition, the company previously partnered with HEXA Renewables to supply 1,000 small-scale solar plants with a total capacity of 100MW, to be completed by the end of 2028.
Responding to limited land availability
As available land for large-scale renewable projects becomes increasingly scarce in Japan, many major renewable energy developers are turning to small, distributed power plant portfolios to ensure continued growth.
This latest partnership strengthens ENEOS Renewable Energy’s strategy to diversify its clean energy portfolio and expand its footprint in the Kansai region, which plays a central role in Japan’s ongoing decarbonization and energy transition efforts.
