Located at an historic crossroads of power lines, this new substation will improve the quality of electricity supply and facilitate the energy transition in the department.
The network in the upper Allier valley was built in the 1930s. One of the first to have electricity in France, the area is at the crossroads between the Lozère, Ardèche, Haute-Loire and Cantal departments. The construction by RTE of the Montgros substation and its connection to the existing substation in Langogne will start a new chapter in this story. Thanks to RTE’s €30 million investment, the electricity network in the Lozère will be stronger thanks to the existence of two 225 kV substations.
RTE notably went out of its way to protect the local landscapes and environment. All new lines were built underground, so no new towers were added.
A total of 14 km of underground cables were also added between Montgros and Langogne.
