NKT high-voltage DC power cable for BorWin5 offshore wind connection


NKT has received a turnkey contract from TenneT, worth of below €250 million, to deliver and install a high-voltage DC (direct current) XLPE power cable system for the BorWin5 project in Northern Germany.

The order comprises the manufacturing of approximately 230 km of 320 kV high-voltage DC on-and offshore power cables and accessories as well as offshore installation by the cable-laying vessel NKT Victoria.

“Over the past years, NKT has established itself as a key partner in the green transformation of Europe. We have completed a number of power connections ensuring transmission of renewable energy and during 2020 we were awarded more interconnector projects as well as this new offshore wind farm connection in Germany. The BorWin5 project win proves the value of our long-term collaboration with TenneT and confirms our strong position as a high-voltage DC solution provider.”

NKT president and CEO Alexander Kara.

The contract value of below €250 million in market prices corresponds to below €235 million in standard metal prices. The power cables have an expected production start end-2021 with project commissioning in 2025.

BorWin5 is TenneT’s fourth offshore wind DC project off the coast of Borkum in north-western Germany. It connects the offshore converter platform BorWin epsilon in the North Sea to the future converter station in Garrel/Ost close to Cloppenburg in Lower Saxony.

As part of Germany’s transformation towards renewable energy supply, a 15 GW offshore wind power capacity is to be available by 2030, and with its 900 MW, BorWin5 is an important step to achieve this target.

NKT adds to the green transformation with power cables produced in a plant running on 100% green electricity and with the purpose-built NKT Victoria being the industry’s most advanced and energy-efficient cable-laying vessel.
