Eurus Energy Holdings and Looop signed a framework agreement to develop high-voltage solar power plants, the companies announced on November 10, 2026.
According to the statement, Looop will handle site acquisition and engineering, procurement, and construction (EPC) of the projects. Completed assets will be transferred to Eurus Energy, which will own and operate them and supply their output to offtakers.
Under the partnership, the companies will initially explore the development of high-voltage solar plants targeting commercial operation between 2027 and 2028. They plan to collaborate on more projects in the future but did not disclose specific targets.
Looop launched its solar development business in 2011 and later entered into power retail. It has now also expanded into grid-scale battery storage, agreeing in June 2026 to develop and build an 8.36MWh project for Tokyo Asset Solution that Eurus Energy will aggregate.
Primarily a wind developer, Eurus Energy grew its solar portfolio when it absorbed another Toyota Tsusho subsidiary, Terras Energy, in April 2025. According to its website, the company holds stakes in 57 operational solar projects in Japan totaling 735.11MW.
