TSOs submitted LanWin6 in Netzentwicklungsplan (NEP) 2037/2045 (2025) 2nd draft, published 13 March 2026. The plan identifies LanWin6 as a required offshore grid connection system (ONAS) to reach the 70 GW statutory target. Pending BNetzA confirmation under §12c EnWG.
On 22 May 2025, 50Hertz Transmission GmbH published an EU contract notice for the procurement of the 2 GW Offshore and Onshore Converter System "North Sea Connector 2" (NSC2), initiating the tender process for a complete converter system. NSC2, which must be ready for trial operation by March 2034, comprises the LanWin6 offshore grid connection (NOR-12-3) and the DC32 onshore link, connecting offshore wind sites N‑12.4 and N‑12.5 via an offshore converter station and DC sea and land cables to the planned four‑terminal NordHub at Pöschendorf.
In 2024, 50Hertz initiated early development activities for the LanWin6 (NOR-12-3) 2 GW HVDC offshore grid connection in the German North Sea, launching preparation for the project’s route and site investigations and beginning tender preparation, including evaluation of different award models.

On 29 September 2023, 50Hertz signed project and framework contracts with cable manufacturers NKT and Prysmian, under which NKT was formally awarded responsibility for implementing the 525 kV HVDC cable system for the LanWin6 offshore grid connection (NOR-13-2) in the German North Sea, alongside the onshore DC32 project. The multi-year framework, part of 50Hertz’s EUR 4.6 billion cable investment programme, includes a firm contract for LanWin6 covering approximately 900 km of core cables to connect 2 GW of offshore wind capacity to the onshore grid between Pöschendorf and Klein Rogahn, with engineering, production, and installation of the cable systems scheduled to start in 2025 and complete in the mid‑2030s.
