TenneT’s blog article "Milestone Land station Maasvlakte in the spotlight" (published 13-2-2025) states that, after completing the hall and converter station for IJmuiden Ver Beta, "work on the connection for IJmuiden Ver Gamma is set to begin in the first quarter of 2026." This is taken as the start of onshore construction for the IJmuiden Ver Gamma grid connection.
Windpowernl reported on 26 May 2025 that contractor consortium NRG started the first horizontal directional drilling campaign under the dunes on Maasvlakte for TenneT’s IJmuiden Ver Beta and Gamma connections. The same article notes that behind the dunes the electricity cables "are currently being laid in the ground on land", indicating that the onshore HVDC export cable installation for the IJmuiden Ver Beta/Gamma connections was underway by May 2025.
Under a framework agreement with TenneT, the GE Vernova–Seatrium consortium was appointed to supply and deliver the 2 GW offshore converter platform for the IJmuiden Ver Gamma offshore grid connection, alongside platforms for IJmuiden Ver Beta and Nederwiek 2. These Dutch projects will connect to the high-voltage grid at Maasvlakte (Rotterdam) as part of TenneT’s 2 GW programme.

IJmuiden Ver Gamma is the 2 GW HVDC offshore grid connection system being developed by TenneT to transmit power from the IJmuiden Ver Gamma wind area (Gamma‑A and Gamma‑B) to shore. The connection uses a standardised 2 GW ±525 kV HVDC architecture: wind farm output is collected via 66 kV array ca...

TenneT awarded energy and marine consultancy ABL a contract to provide marine warranty survey services for the installation of the 2 GW export cable systems for IJmuiden Ver Gamma, IJmuiden Ver Beta and Nederwiek 2, all within its 2 GW offshore grid programme in the Netherlands. ABL’s Hamburg-based German branch will manage technical review and approval of documentation, suitability surveys, and on-site attendances at fabrication, loadout and offshore operations, with the scope running through to 2029.
In June 2023, the definitive inpassingsplan, environmental impact report (MER), and associated decisions for Net op zee IJmuiden Ver Gamma were finalised, with no appeals lodged, making the decisions irrevocable and thereby granting overall planning/development consent for the offshore grid connection project. The decisions are coordinated and published via Bureau Energieprojecten.
Transmission system operator TenneT selected NKT to deliver and install the 525 kV XLPE HVDC export cable system for the IJmuiden Ver Gamma offshore grid connection, as part of a wider award covering IJmuiden Ver Beta and Nederwiek 2. Under the contract, NKT will handle design, engineering, production, delivery, project management, and offshore and onshore installation of the approximately 2 GW cable link landing at Maasvlakte (Port of Rotterdam).
As part of the statutory planning procedure for Net op zee IJmuiden Ver Gamma, the draft integration plan (Ontwerp-inpassingsplan), Environmental Impact Report (MER) and draft decisions (Ontwerpbesluiten) were published and made available for inspection between December 2022 and April 2023, indicating that these planning documents had been formally submitted into the Dutch planning process for the grid connection project.
On 17 September 2021, a second public consultation phase for the IJmuiden Ver Gamma Offshore Grid commenced with the publication of the draft Memorandum Scope and Level of Detail (MSLD) and an updated participation plan. The draft MSLD, describing routing options and environmental aspects to be assessed in the EIA, was open for public review and comment until 29 October 2021.
A statutory public consultation on the IJmuiden Ver Gamma Offshore Grid was opened with the publication of the notification of intent and participation plan on 8 April 2021. From 8 April to 21 May 2021, these documents were available for public review so that stakeholders and the general public could submit comments as part of the EIA and permitting process led by the Ministry of Economic Affairs & Climate Policy and TenneT.
An exploratory seabed survey along the planned IJmuiden Ver Gamma Offshore Grid cable corridor was completed, providing detailed seabed and archaeological information that allowed TenneT and its consultants to optimise the export cable route within the corridor and avoid obstacles and archaeological remains by rerouting the cable by several tens of metres where necessary, thereby reducing archaeological impacts and lifecycle costs.
