Rhein-Main-Link

Eiffage and De Romein, as part of a consortium, win partnership contract to deliver the civil engineering for Amprion’s future project Rhein-Main-Link in Germany

Eiffage, through its German subsidiary Eiffage Infra-Bau, in a 50/50 joint venture with the Dutch established De Romein Group, has won the partnership contract, awarded by the German TSO Amprion GmbH for the civil engineering of the infrastructure needed to transport electricity produced by offshore wind farms in the North Sea to the Rhein-Main region in southern Germany.

The contract involves the creation of an energy corridor from Lower Saxony to the economic region of Hesse by building a 600-kilometre cable conduit system.

Following a design phase carried out in collaboration with Amprion, the work will be delivered between 2028 and 2032. Once completed, this corridor will accommodate four electricity transmission lines, each with a capacity of 2 GW. The total 8 GW transmitted will meet the growing electricity needs of the Rhein-Main region, providing low-carbon energy to both industries and its nearly six million inhabitants.

The project was awarded as a partnership contract, enabling the consortium to define, in conjunction with Amprion GmbH, the exact nature of the civil engineering works to be carried out for each phase of the project. For each section, a target price, taking into account specific local features, will be agreed between the project stakeholders.
