Eiffage Construction has signed a contract with RTE for the construction of 450 industrialized modular buildings to be installed at electrical substations across mainland France.

The contract covers the technical design, manufacture, and installation of 1,125 timber-frame prefabricated modules for the substations. Their on-site assembly will result in the completion of 450 buildings.

RTE has launched a vast industrial modernization program for the grid, aimed at adapting existing infrastructure to climate change and enabling the country's electrification. The modules provided will house medium and extra-high voltage equipment, meeting the complex technical requirements of RTE's sites.

Initial deliveries are scheduled for the second quarter of 2026.
