LanWin7 (project ID NOR-12-4) is a 2,000 MW offshore HVDC grid connection system being developed as part of the German North Sea build‑out. The scheme will use ±525 kV XLPE HVDC technology to transmit wind power from the offshore areas N‑12.4 and N‑12.5 to shore. Published planning material and r...
TSOs submitted LanWin7 in Netzentwicklungsplan (NEP) 2037/2045 (2025) 2nd draft, published 13 March 2026. The plan identifies LanWin7 as a required offshore grid connection system (ONAS) to reach the 70 GW statutory target. Pending BNetzA confirmation under §12c EnWG.
On 27 December 2024, TenneT, the Dutch-German transmission system operator, selected Danish manufacturer NKT under its existing framework agreement to deliver the 525 kV XLPE HVDC on- and offshore power cable system for the LanWin7 offshore grid connection. LanWin7, which will have a route length of about 320 kilometres and is part of TenneT’s 2 GW programme, was awarded to NKT together with a partial section of the NordOstLink project, with the two awards having a combined value of approximately EUR 1 billion covering cable design, engineering, production, and on- and offshore installation; call-off of the specific project contracts is expected in 2026–27, with commissioning of the projects anticipated in 2033–34.
