Prysmian PowerLink s.r.l, part of Prysmian Group, the world pioneer in the energy and telecom cable systems industry, has been awarded new contracts worth in total of around €1.1 billion by 50Hertz, a transmission grid operator in Germany.
offshore wind projects
As part of the 50Hertz “long-term EPCI contracts for HVDC cables” tender, Prysmian has received an award for Lot2 which includes EPCI contracts for the NOR-11-1 submarine and DC31 land projects along with Lot7.
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.
design, manufacture, supply, installation
DC31 is a 525 kV HVDC underground cable project and is planned to transmit power from the Heide/West area
Under Lot 2, 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 1,000 km.
With a power transmission capacity of 2 GW, NOR-11-1 is a 525 kV HVDC submarine project utilizing 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 project of Lot2, the DC31 is a 525 kV HVDC underground cable project and is planned to transmit power from the Heide/West area to Klein Rogahn.
Submarine power cables
Both submarine and land HVDC (High Voltage Direct Current) ±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 fiber optic cable.
Submarine power cables will be produced at the Group’s centers of excellence in Pikkala, Finland, and Arco Felice, Italy and the submarine fiber 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.
state-of-the-art cable-laying vessels
Prysmian will leverage its fleet of state-of-the-art cable-laying vessels to perform marine installation operations
In addition, Prysmian has been awarded as the primary supplier for Lot7, which 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 2,700 km within an agreed period.
Prysmian will leverage its fleet of state-of-the-art cable-laying vessels to perform marine installation operations, including the laying and burial of offshore cables.
Green energy use
"We are happy to collaborate and strengthen our partnership with 50Hertz on these important projects and contribute to the German 'Energiewende' with our solutions and experience, supporting the growth of green energy use in Germany and around the world," commented Hakan Ozmen, EVP Projects BU, Prysmian Group.
“This long-term contract will consolidate Prysmian’s relationship with 50Hertz and confirms the Group’s commitment to assisting our key customers during the whole life of cable systems,” stated Detlev Waimann, Chief Commercial Officer of Prysmian Power Link, Prysmian Group.
