Voltalia, an international renewable energy player, holds at the end of 2025 a total capacity of 3,554 megawatts, including 2,913 megawatts in operation. Commenting on the achievement, Robert Klein, CEO of Voltalia, said, “With around 3.6 gigawatts in operation and under construction, Voltalia has achieved its 2025 total capacity target. This performance confirms the strength of our growth strategy, despite annual production being impacted by curtailment constraints, which will be largely offset over the next two years.”
The renewable energies player commissioned 408 megawatts during 2025, mainly in Africa and other regions, including: South Africa: 148 megawatts of solar, with the Bolobedu plant under testing phase since late December 2025; Uzbekistan: 126 megawatts of solar with the Sarimay Solar plant; United Kingdom: 45 megawatts of solar with the Clifton plant; French Guiana: 11 megawatts hybrid (Sinnamary biomass plant combined with a battery storage system); Brazil: 7.5 megawatts, with the Cafesoca hydro plant entering the testing phase and producing its first megawatt-hours in December; and Helexia in Europe and Brazil: 63 megawatts commissioned.
In addition, Voltalia continued its strategy of acquisitions and disposals of plants, including: Greece: acquired 11 megawatts of solar plants; and France: sold 24 megawatts of solar plants.
The operating capacity therefore reaches 2,913 megawatts, representing a growth of +16%.
