PRESS RELEASE January 9, 2024

Voltalia exceeds its capacity targets

Voltalia (Euronext Paris, ISIN code: FR0011995588), an international player in renewable energies, exceeds its 2023 targets for total capacity (in operation and under construction) and capacity in operation.

Initially set at 2.6 gigawatts in June 2019, the total capacity target was raised to 2.8 gigawatts in October 2023. Now at 2.85 gigawatts, total capacity has been multiplied by 2.8 since June 2019.

The target for capacity in operation, initially set at 2.3 gigawatts in October 2023, has now been exceeded, at 2.37 gigawatts. Since June 2019, capacity in operation has increased by a factor of 4.4, thanks in particular to growth of 50.9% in 2023 alone.

Sébastien Clerc, CEO of Voltalia, said: "We have exceeded by 10% the target of 2.6 gigawatts of total capacity that Voltalia had set itself for 2019, just before the Covid-19 pandemic, which nevertheless slowed down the granting of administrative authorisations and construction work. This performance is the fruit of the joint efforts of Voltalia's development, construction, maintenance, financing and support specialists."

The capacity of power plants in operation grew by an exceptional +50.9% in 2023, from 1,571 to 2,370 megawatts. The record volume of power stations commissioned in 2023 has reduced the stock of power stations under construction from 1,022 megawatts at the end of 2022 to 480 megawatts at the end of 2023. In total, the capacity of power plants in operation and under construction has increased by around 10% in 2023.

Solar technology, both ground-mounted and rooftop, continues to grow rapidly, to reach 66% of Voltalia's power plants in operation and under construction, compared with 60% by the end of 2022.

Voltalia has commissioned 795 megawatts throughout 2023:

• In France: 80.3 megawatts of solar, wind and battery storage capacity, at the Sable blanc, Montclar, Sud Vannier and Rives charentaises sites;
