What TTR Energy does

TTR Energy is an independent Franco-Belgian renewable energy industrial company founded in 2008, headquartered in Brussels with French operations based in Reims. The company specializes in the development, financing, construction and operation of onshore wind farms in France, with a growing extension into agrivoltaics and the repowering of aging wind installations. Across its 17-year history it has built or initiated construction on 41 projects totaling 1,064 MW, holds 800 MW of permits for future projects, and currently manages 607 MW of operational capacity through dedicated portfolio vehicles, with a cumulative investment portfolio value of €1,974M and a track record of 60+ acquisitions and disposals.

The company's underlying technology stack centers on full-lifecycle project execution rather than proprietary hardware: it integrates environmental and acoustic studies, regulatory authorization (including French aviation and military constraints), wind resource assessment, grid connection engineering, turbine procurement across all major OEMs (Siemens Gamesa, Vestas, Nordex, GE, Enercon), construction management, and long-term asset management. Its agrivoltaic offer pairs bifacial single-axis trackers — claimed to deliver 15–25% additional output via ground reflection — with breeding systems on minimum 30-hectare agricultural land. TTR also operates a repowering capability replacing older turbines with newer-generation units, demonstrated by a 2.6x production uplift on its first Aisne project.

Commercially, TTR runs a hybrid developer-operator-investor model. Revenue streams include one-time project development and sale fees, recurring asset management fees on managed vehicles (Hexagon Renewable Energy, Ocarina Energy), direct equity participation alongside financial partners (notably Green Fund IV with Degroof Petercam, in which TTR holds an 11.30% stake), and construction management services. Customers are institutional LPs and co-investors (Amundi Transition Énergétique, Belgian insurer consortium Patronale Life/Fédérale Assurance/Argen-co, Green Electricity Master Invest IV), with the company serving exclusively the French territory. TTR is privately held, co-founded by Gauthier De Potter (Co-CEO) and Christophe Gilain, and led by COO Guillaume Orianne and CFO Nicolas Verdbois.
