The 18 km Fehmarnbelt tunnel’s electric train operations, motorway, ventilation, lighting and other systems will require a constant and reliable power supply. The tunnel will, therefore, have its own transformer station close to the tunnel portal at Rødbyhavn.
The contract to construct the transformer station has today been awarded to the Spanish company, Elecnor. It has a value of approximately DKK 300 million.
Elecnor has extensive experience with similar projects across Europe.
The transformer station will be one of the largest facilities of its type in Denmark. It will supply power to the Fehmarnbelt tunnel’s railway and 10 km of railway on the island of Lolland as well as to the tunnel’s technical installations.
The contract sets high energy efficiency requirements and Femern A/S has stipulated that the transformer station should have the capacity to serve the electric means of transport of the future, including charging stations for electric vehicles.
"The transformer station at Rødbyhavn is central to the operation of the electrical systems in the Fehmarnbelt tunnel itself and the railway. It is also an important aspect of the Fehmarnbelt tunnel’s contribution to the green transition of the transport sector. We look forward to working with Elecnor on a facility that will not just ensure power supplies, but also comply with our requirements that the tunnel operations will be CO2-neutral following the opening in 2029,” says Jens Ole Kaslund, Technical Director, Femern A/S.
Preparatory works on the transformer station began earlier this year. Elecnor will begin the construction of the transformer station itself in 2023. It will be completed in phases and is expected to be ready in 2028.
