Hesselø Export Cable denotes the planned high-voltage AC export connection that will transmit power from the 800–1,200 MW Hesselø Offshore Wind Farm in the Kattegat to the Danish 400 kV transmission grid at Hovegård. Current planning documents from the Danish Energy Agency and Energinet describe ...

According to the Danish Energy Agency’s 2022 timetable, the Environmental Impact Assessment (EIA) of the offshore-based part of the Hesselø project, including offshore turbines and export cables, is expected to be carried out in 2025–2026, with the scoping phase planned for 2025. This scoping phase will include an early public consultation where stakeholders can comment on which topics and environmental impacts should be addressed in the offshore EIA.
On 19 July 2024, the Danish Energy Agency approved the plan for Hesselø Offshore Wind Farm based on the Strategic Environmental Assessment (SEA) and the consultation responses received. The decision confirms that the plan, which sets the general framework for the future construction of Hesselø OWF and its grid connection, can be adopted, although it does not by itself authorise construction of facilities.
As outlined in October 2022, the Danish Environmental Protection Agency expects around mid‑2024 to issue the EIA‑permit (§25 of the Danish Environmental Assessment Act) for the land‑based part of the Hesselø project, covering the onshore grid connection including the export cable landfall at Gilbjerg Hoved, a new high‑voltage station near Pårup, and onshore cables to the existing Hovegård substation. Issuance of this permit is contingent on the EIA process demonstrating that the land‑based works can be carried out.

On 5 February 2024, the Danish Energy Agency opened the second public consultation on the Strategic Environmental Assessment (SEA) of the plan for the revised southern location of Hesselø Offshore Wind Farm. The consultation on the revised SEA of the plan, which runs from 5 February to 5 April 2024 and includes a public meeting in Gilleleje, invites comments on the environmental report and the updated plan framework that covers the wind farm and its grid connection.
On 10 October 2022, following a climate agreement that moved Hesselø Offshore Wind Farm to an area south of the original site, the Danish Energy Agency launched a supplementary five‑week early public hearing on the revised sea‑based part of the Strategic Environmental Assessment (SEA) of the plan for Hesselø Offshore Wind Farm. The consultation, running from 10 October to 14 November 2022, invited stakeholders to submit ideas on the revised offshore plan, including implications for the offshore export cable routes.
On 22 August 2022, the Danish Energy Agency released the report "Hesselø OWF Landfall - Site Investigations For Horizontal Directional Drillings", confirming completion of geotechnical investigations at the Gilbjerg Hoved landfall site to support design of the Hesselø export cable’s horizontal directional drilling shore crossing.
On 19 April 2022, the Danish Energy Agency published the Hydrographical Report for the Hesselø export cable routes, marking completion and reporting of hydrographic and related seabed surveys along the planned submarine export corridors from the offshore wind farm area towards Zealand.
On 12 February 2021, the Danish Energy Agency and the Danish Environmental Protection Agency opened an early public consultation in the scoping phase for the Strategic Environmental Assessment (SEA) of the plan for the Hesselø Offshore Wind Farm and the Environmental Impact Assessment (EIA) of the land-based part of the project, including the grid connection via offshore export cables to Gilbjerg Hoved, a potential new high‑voltage station near Pårup, and onshore cables to the Hovegård substation. The consultation period ran from 12 February to 19 March 2021, during which stakeholders were invited to submit ideas on topics and environmental impacts to be assessed.
Energinet awarded Rambøll a contract to carry out an export cable route survey for the Hesselø grid connection option with landfall at Gilleleje (Gilbjerg Hoved), following a separate tender process from an earlier Kyndby route. This procurement covers detailed survey work along the proposed offshore export cable route that will connect the Hesselø Offshore Wind Farm to the onshore grid via the Gilbjerg Hoved landfall and associated transmission infrastructure.
In early October 2020, Energinet started surveys along the two proposed Hesselø export cable routes towards potential landfalls at Gilbjerg Hoved and Kyndby in North Zealand, parallel to offshore site investigations for the wind farm and its grid connection.
