Prysmian PowerLink, part of Prysmian Group, has been awarded new contracts worth in total around €1.1 billion by 50Hertz, a transmission grid operator in Germany. As part of the 50Hertz “long-term EPCI contracts for HVDC cables” tender, Prysmianhas received an award for Lot2 – which includes EPCI contracts for the NOR-11-1 submarine and DC31 land projects – and Lot7, a framework provision allowing 50Hertz to contract future 525 kV offshore and/or onshore projects.
These projects are part of Germany's overall goal to reach a cumulative installed capacity of 70 GW by 2045 for offshore wind and to transfer the energy generated in the North Sea to consumers in the eastern and southern regions of Germany.
Under Lot2, Prysmian will be responsible for the design, manufacture, supply, installation, testing and commissioning of the two turnkey projects NOR-11-1 and DC31 with an overall cable length of around 1000 km. With a power transmission capacity of 2 GW, NOR-11-1 is a 525 kV HVDC submarine project utilising submarine cable plus underground cable along the route that is planned to connect the offshore windfarm area N-11-1 to the German grid in the Heide/West area. The second Lot2 project, the DC31, is a 525 kV HVDC underground cable to transmit power from the Heide/West area to Klein Rogahn.
Both submarine and land high voltage direct current (HVDC) ±525 kV cable systems will consist of two single-core copper cables with XLPE insulation plus a dedicated XLPE metallic return (DMR) cable and a fibre optic cable. Submarine power cables will be produced at the Group’s centres of excellence in Pikkala, Finland, and Arco Felice Italy; the submarine fibre cables will be manufactured in Nordenham, Germany. The underground power cables covering both the DC31 and the underground part of the NOR-11-1 project will be produced in France.
For Lot7 Prysmian has been awarded a primary supplier contract. The project consists of a framework provision allowing 50Hertz to contract future 525 kV offshore and/or onshore projects with a cable core length volume of up to 2700 km within an agreed period.
