Doordewind (west) is the label used in the draft Partiële Herziening for the west-side reserved extension of windenergiegebied Doordewind in the Dutch part of the North Sea. Once adopted, it is treated as part of the contiguous windenergiegebied Doordewind, planned for four kavels with a combined...
On 1 May 2026, through the Partial Revision of the North Sea Programme 2022–2027, the Dutch Cabinet designated an expansion of the Doordewind wind energy area and formally established the new wind energy area Doordewind II with 2 GW of capacity. This programme revision, overseen by the Ministry of Climate Policy and Green Growth, increases planned offshore wind capacity in the Routekaart windenergie op zee from 21 GW to 23 GW and confirms that TenneT is mandated to provide all grid connections for Doordewind II.
On 1 May 2026, the Dutch government, via the partial revision of the North Sea Programme 2022‑2027, formally designated the Doordewind II wind energy area as a 2 GW offshore wind zone in the North Sea and confirmed that TenneT will provide the associated grid connection, increasing the Dutch offshore wind roadmap volume from 21 GW to 23 GW.
On 2 April 2026, the Dutch Minister of Climate Policy and Green Growth (KGG) and the Minister of Housing and Spatial Planning (VRO) adopted a new preparatory decision (voorbereidingsbesluit) for the Wind op zee Doordewind project, again covering the full Doordewind wind energy area including the future Doordewind II site. Published in the Staatscourant on 2 April 2026 and effective from 3 April 2026, the decision continues to block other building and related activities in the area that could obstruct construction of the offshore wind farms until the kavelbesluit is issued, and it cannot be appealed.

On 20 March 2026, Minister Karremans (Ministry of Infrastructure and Water Management) submitted the adopted Partieel Herziene Programma Noordzee 2022–2027 (March 2026 version) to the Tweede Kamer. The revised programme formally reconfirms ("herbevestigt") Doordewind as a wind energy area with an adjusted shape and a westward extension: in addition to the already-planned 2 GW kavel (part of the 21 GW Routekaart), Doordewind now provides space for approximately 2 GW extra, bringing the contiguous zone to around 4 GW. The southern strip of the area was removed for shipping safety and the western extension was added to align with the adjacent shipping route and German wind farm development. Lagelander was dropped from the programme (no longer a wind energy area or search area), while Doordewind, Search Area 6/7, and the existing zones are reaffirmed. The capacity figure remains indicative pending ecological research and kavelbesluit-stage detailing; the document keeps the option open to refine extent and timing. This adoption transitions Doordewind (west) from the draft Concept-NRD stage (October 2025) into the formally-adopted national spatial framework for the Dutch North Sea, paving the way for subsequent kavelbesluit procedures for the additional ~2 GW.
As part of the North Sea Programme 2022–2027 partial review, the Dutch government expanded the Doordewind wind farm zone with a new westward extension referred to as Doordewind (west). The draft Concept Note on Scope and Level of Detail for the environmental impact assessment describes wind farms with a combined installed capacity of 4–4.6 GW in the already designated Doordewind zone and this additional expansion area, and notes that the complete, adapted zone (including the westward extension) is now incorporated in the Dutch Offshore Wind Energy Roadmap towards 21 GW by 2032.
The Dutch government, via Bureau Energieprojecten on behalf of the Ministries of Climate and Green Growth (KGG) and Housing and Spatial Planning (VRO), held a public consultation on the draft Notitie Reikwijdte en Detailniveau (concept-NRD) for the envisaged wind farms in parcels I–IV of the Doordewind wind energy area, which includes the future Doordewind II site; the draft scoping note was available for public inspection and comments from 10 October to 20 November 2025.
In July 2025, the Dutch Ministry of Climate Policy and Green Growth selected the Schiermonnikoog‑Wantij route as the preferred corridor (voorkeursalternatief, VKA) for TenneT’s Net op Zee Doordewind grid connection, defining the cable route that will bring 4 GW from the Doordewind I and II offshore wind farm sites ashore at Eemshaven via two 2 GW underground cable systems.
In mid‑2025, RVO prepared detailed constraint mapping for the Doordewind wind energy area, including the planned Doordewind (west) extension, as input to the environmental impact assessment. The mapping documents shipping lanes and traffic separation schemes near the zone, Natura 2000 and Marine Strategy Framework Directive areas such as the Friese Front, existing oil and gas activities in mining block G14, as well as existing cables, pipelines, helideck infrastructure, and other spatial constraints, all based on data available in July 2025.
On 24 April 2025, the Dutch Minister of Climate Policy and Green Growth (KGG) and the Minister of Housing and Spatial Planning (VRO) issued a preparatory decision (voorbereidingsbesluit) for the Wind op zee Doordewind project area, covering up to 4 GW of wind capacity including the future Doordewind II site. The decision, which entered into force on 25 April 2025, prevents new developments in the area that could hinder or make construction of the offshore wind farms impossible until the kavelbesluit (site decision) is published.
By 28 March 2025, G‑TEC had completed a seabed geophysical survey in the Doordewind Wind Farm Zone for RVO, acquiring, processing and delivering multibeam echosounder, side‑scan sonar, sub‑bottom profiler and magnetometry data that will feed into the Integrated Ground Model and upcoming geotechnical investigations, and be published for use by participants in permit tenders for the Doordewind I and II sites.
In 2024, the Dutch government decided that Doordewind Wind Farm Site II (Doordewind II) would not be developed within the 21 GW Offshore Wind Energy Roadmap planned to be realised by the end of 2032, effectively deferring the 2 GW site to a later development phase while Doordewind Site I remains scheduled to be fully operational in Q4 2032.
In September 2024, RVO commissioned Fraunhofer IWES, together with Tetra Tech RPS Energy and Geowynd, to develop an Integrated Ground Model (IGM) and Geotechnical Interpretative Report for the entire 565 km^2 Doordewind Wind Farm Zone, covering both Site I and Site II, and to plan subsequent offshore geotechnical investigations. The IGM synthesises geophysical and geotechnical datasets into a coherent constraints model used to de-risk cable routing, layout and foundation design for future bidders. The contract was reported on 30 September 2024; mapping deliverables are produced progressively and feed into the RVO permit-tender data package.
The TGS three‑dimensional ultra high‑resolution seismic (3D UHRS) soil survey in the Doordewind Wind Farm Zone, commissioned by RVO and covering more than 300 km², was completed by the end of August 2024 after a campaign that started in mid‑June, delivering data intended to support turbine foundation and cable route design for Doordewind I and II.
From mid‑June 2024, TGS began a three‑dimensional ultra high‑resolution seismic (3D UHRS) soil survey over more than 300 km² of the Doordewind Wind Farm Zone under commission from RVO, collecting detailed subsurface data down to about 100 m depth to inform the design of foundations and cable routes for the future 2 GW Doordewind I and II wind farms.
RVO reported in its 12 April 2024 newsletter that it had started geophysical surveys in the Doordewind Wind Farm Zone (“we started the Geophysical Surveys in the area”), covering 2D UHRS/3D UHRS and an additional seabed survey. This confirms geophysical survey fieldwork was underway in April 2024.
