Voltalia announces that it has passed a new milestone in terms of operating and construction capacity: “We are delighted to announce that we have exceeded 3 gigawatts of capacity in operation and under construction. Crossing this threshold confirms the target we set ourselves for 2024, which is around 3.3 gigawatts in operation and under construction, of which around 2.5 gigawatts are in operation,” says Voltalia’s CEO.
Sébastien Clerc emphasizes that “this success is the result of everyone’s hard work and commitment, but today I would like to pay a special tribute to the employees of our Helexia subsidiary in Portugal, who helped us pass the symbolic 3 gigawatt mark.”
With the launch in Portugal of Helexia’s construction of 2 megawatts of solar energy on the roofs of its client Leroy Merlin, the total capacity of Voltalia’s power plants in operation and under construction now exceeds 3 gigawatts.

“EXCEEDING THIS THRESHOLD CONFIRMS THE GOAL WE SET OURSELVES FOR 2024”
