Energy Networks in Île-de-France

Construction, renewal and rerouting of electricity and gas networks. ECR supports ENEDIS, GRDF, GRT Gaz and local authorities across the whole of Île-de-France.

Our expertise

Energy-network specialist

Energy networks comprise the infrastructure that carries and distributes electricity and gas: MV (HTA) and LV (BT) cables, transformer substations, and steel and polyethylene gas pipelines. Building them demands skilled crews, the right equipment and rigorous safety control.

Since 2017, ECR (Euro Câbles Réseaux) has designed and delivered these works for major energy clients in Île-de-France. Our 212 employees work on electricity and gas networks, from earthworks to connection, in full compliance with ENEDIS, GRDF and GRT Gaz specifications.
