The project in details

The repowering project for the Saint-Cirgues-en-Montagne wind farm was initiated in 2022, with the objective of optimizing a site already dedicated to renewable energy production, consisting of 9 wind turbines.

Environmental surveys were carried out throughout 2023 to cover a complete biological cycle (fauna, flora, natural habitats, birdlife, and bats).

At the end of 2024, the municipality of Saint-Cirgues-en-Montagne formally approved the classification of the project area as a Renewable Energy Acceleration Zone (ZAENR), confirming its alignment with the region’s energy transition strategy.

This project aims to replace the existing turbines with 6 wind turbines—fewer but more efficient machines—thus increasing renewable electricity production while controlling environmental impacts.
