Tender launched for Fehmarnbelt tunnel’s electrical systems

Femern A/S has published a tender for the delivery and installation of the electrical systems of the Fehmarnbelt tunnel which connects Denmark and Germany. The contract is worth 750 million euros with the expected award of the contract at the turn of the year 2022/23.

The electrical input of the Fehmarn tunnel is one of the major tasks on the 18-kilometer connection between Denmark and Germany, for which now a tender is launched. The construction of the tunnel started on 1 January 2021. The tunnel will have a four lane motorway and two electrified rail tracks. When it is finished, the journey time by train between Stockholm and Hamburg will be cut by two hours.

Electrical installation

The tender covers both the delivery and installation of the tunnel’s comprehensive systems and electrical  installations. It includes ventilation, lighting, safety systems and maintenance.

Next to the electrical systems, Femern A/S, the company responsible for planning, construction and operation of the tunnel, will be putting out a tender for another major contract in 2021 for a transformer power station, the TPS contract. The station will ensure the supply of electricity for train operations and for the tunnel’s many installations. Femern A/S has published Prior Information Notices (PIN) for both contracts in the EU’s Tenders Electronic Daily (TED).
