As a long-standing partner, SEPALE was present at the inauguration of the Tréveray Saint-Joire wind farm.

The project, developed in partnership with Billas Avenir Energie (BAE), begins in 2013 in the Meuse municipalities of Tréveray and Saint-Joire.

The single environmental authorization was obtained in January 2019 after more than 2 years of appraisal.

SEPALE is continuing its mission with the optimization of connections to the electricity grid, tariffs for the valorization of the electricity produced, and the preparation of the works to achieve this project.

Composed of 13 Vestas V-100 wind turbines with a total output of 28.6 MW, commissioned in stages in late 2021 and mid-2022, its output represents the equivalent of the electricity consumption of around 27,000 people, and the annual saving of almost 28,000 tons of CO2.

SEPALE is pleased to have helped for the realization of this concerted project, for which the involvement and perseverance of local authorities and elected representatives have been very important. This new milestone brings the total installed capacity to 100 MW under the partnership signed back in 2016 with Langa, now part of Engie Green. This represents 6 operational projects, while we await the Sainte-Lizaigne wind farm in the next few days (25MW), the Boixe wind farm already authorized and many others under administrative review.

I would like to thank all those involved in the development and completion of this fine project, one of SEPALE’s most powerful.
