Achievement of the 2025 target for operating and construction capacity of 3.6 gigawatts

Voltalia (Euronext Paris, ISIN code: FR0011995588), an international renewable energy player, holds at the end of 2025 a total capacity of 3,554 megawatts, including 2,913 megawatts in operation

Robert Klein, CEO of Voltalia, stated: “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”.

Capacity in operation

Voltalia commissioned 408 megawatts during 2025, mainly in Africa and other regions, including:

• South Africa: 148 megawatts of solar¹, with the Bolobedu plant under testing phase since late December 2025;
• Uzbekistan: 126 megawatts of solar² with the Sarimay Solar plant;
• United Kingdom: 45 megawatts of solar³ with the Clifton plant;
• French Guiana: 11 megawatts hybrid (Sinnamary biomass plant combined with a battery storage system)⁴;
• Brazil: 7.5 megawatts, with the Cafesoca hydro plant entering the testing phase and producing its first megawatt-hours in December⁵;
• Helexia in Europe and Brazil: 63 megawatts commissioned.

In addition, Voltalia continued its strategy of acquisitions and disposals of plants:

• Greece: Voltalia acquired 11 megawatts of solar plants;
• France: Voltalia sold 24 megawatts of solar plants⁶.

The operating capacity therefore reaches 2,913 megawatts, representing a growth of +16%. It is distributed as follows: 54% in Latin America, 33% in Europe, and 13% in the rest of the world.

Capacity under construction

Voltalia launched construction works for 305 megawatts during 2025, bringing the total under construction to 641 megawatts. This capacity is distributed as follows: 58% in Europe, 31% in Africa and International, and 11% in Latin America.

• Uzbekistan: 200 megawatts from the Artemisya complex, including 100 megawatts / 200 megawatt-hours of battery storage system and 100 megawatts of wind⁷;
• French Guiana: 84 megawatts from the Sainte-Anne hybrid project, including 44 megawatts of solar, 34 megawatts (135 megawatt-hours) of battery storage system, and 7 megawatts hybrid⁸;
• Colombia: 20 megawatts of solar⁹ with the Los Venados plant.

In total, the capacity of plants in operation and under construction increased by 298 megawatts (+9%) in 2025, reaching 3,554 megawatts.
In addition, Voltalia has recently secured new long-term power sales contracts in Italy for a total of 68 megawatts¹⁰, further strengthening its position in the country and across Europe.

Production update

Production is below forecasts due to curtailment, with a curtailment rate observed higher than anticipated (21% versus 10% expected over the first nine months)¹¹. Detailed figures for the fourth quarter and the full year 2025 production will be disclosed conjointly with the 2025 turnover.

Voltalia continues its legal and litigation efforts to obtain compensation for curtailment. Progress in discussions in Brazil could allow the implementation of compensations as early as 2026, covering curtailment impacts observed between September 2023 and the end of 2025. Voltalia will inform the market of any significant developments regarding this situation.

Update on 2025 EBITDA target

Voltalia reaffirms its EBITDA target of between 200 and 220 million euros and expects a net loss attributable to the Group in the second half to be higher than in the first half of 2025.

Next milestone: Q4 2025 turnover, on 28 January 2026 (after market close)
