The Danish Energy Agency initiates the second public consultation regarding the plan for Hesselø Offshore Wind Farm
05-02-2024
The Danish Energy Agency invites the public, companies, authorities and other interested in the coming Hesselø OWF to submit remarks on the Strategic Environmental Assessment (SEA) of the plan for the revised southern location of Hesselø OWF.
The public consultation of the revised SEA of the plan for Hesselø OWF runs from the 5 February to 5 April 2024. In connection with the consultation, a public meeting will be held in Gilleleje, where the results of the environmental report will be presented.
The public meeting will be held on 19 March from 16.00 - 19.00 in Kulturhavn Gilleleje, Peter Fjeldstrup's vej 12, 3250 Gilleleje. There will be a presentation at 17.00. It is not necessary to register for the public meeting.
Read relevant hearing material, information on how to submit inputs to the hearing etc.
The further process for Hesselø OWF
After the consultation, the Danish Energy Agency will examine the remarks, and if necessary update the plan accordingly. Hereafter, the Danish Energy Agency will make a SEA Summary Statement and publish the final plan.

The Danish Energy Agency launches a supplementary 5-weeks public hearing concerning the sea-based part of the strategic environmental assessment of the plan for Hesselø Offshore Wind Farm
10-10-2022
Due to the Climate Agreement on green electricity and heat of 25 June 2022, Hesselø Offshore Wind Farm moves to an area south of the original Hesselø area.
The Danish Energy Agency invites the public, companies, authorities and other interested in the coming Hesselø Offshore Wind Farm to submit ideas on the revised sea-based part of the strategic environmental assessment (SEA) of the plan for Hesselø Offshore Wind Farm.
The public hearing, which is an early public consultation in the scoping phase, runs from the 10 October to 14 November 2022.
Read relevant hearing material, information on how to submit inputs to the hearing, etc. (in Danish)
The Danish Energy Agency is the responsible authority for the SEA of the plan. Based on the ideas and inputs received during the consultation, the Danish Energy Agency will decide what topics and environmental impacts to be included in the SEA.
The results of the environmental assessment should be published and subject to a public consultation in the first half of 2024. The Danish Environmental Protection Agency expects mid-2024 to issue the EIA-permit (§ 25 of the Danish Environmental Assessment Act) for the land-based part of the project, provided that the EIA-process allows the project to be carried out.
The EIA of the offshore-based part of the project is expected to be carried out in 2025-2026 when the winner of the tender for Hesselø Offshore Wind Farm has been found: the scoping phase is expected to be in 2025 and the 2nd public consultation on the EIA report is expected to be in 2026. Later in 2026, the Danish Energy Agency expects to issue the construction license (EIA-permit) for Hesselø Offshore Wind Farm, provided that the EIA-process allows the project to be carried out.

New agreement on an alternative location for Hesselø offshore wind farm
27-06-2022
The location for Hesselø Offshore Wind Farm is moving south to reduce risk in establishing the wind farm while also accommodating conflicting interests in the area.
Renewed preliminary investigations are necessary. Hence the need to postpone the call for competition. Further information will follow during the first quarter of 2023 in a renewed preliminary market consultation. The Danish Energy Agency expects the receipt of tenders to be during the second half of 2024. Deadline for full commissioning of the wind farm is by the end of 2029.

Gilbjerg Hoved chosen as landfall for Hesselø grid connection
23-10-2020
The Danish Energy Agency (DEA) and Energinet have decided, that the export cables from Hesselø Offshore Wind Farm (Hesselø OWF) will have its landfall at Gilbjerg Hoved, west of Gilleleje on the north coast of Sealand. Thus, the alternative landfall option – included in the granted license for preliminary investigations to Energinet – at Kyndby in Isefjord is cancelled.
The choice has been made primarily based on considerable cost savings for the concession owner. The chosen route with landfall at Gilbjerg Hoved requires considerably shorter subsea export cables compared to the alternative landfall option, and will thus be associated with lower total cable costs, even though this landfall option requires longer onshore cables than the alternative. The onshore export cables from Gilbjerg Hoved to the Point of Connection in the collective transmission grid at Hovegård, which the concession owner will own and be responsible for installing, will be approximately 50 km.
Energinet estimates that the landfall at Gilbjerg Hoved provides a technically substantially better project than the alternative option. Furthermore, Energinet estimates, that the concession owner can install the required cables and substations with no likely significant effects on the environment. Moreover, Energinet estimates that the overall installations can be done within the time frame, which gives the concession owner 5 years from the concession is rewarded, until the wind farm has to be fully commissioned.
Energinet will carry out preliminary investigations onshore and offshore, including SEA for the plan for Hesselø OWF and the EIA for the onshore project. The concession owner will carry out the EIA for the offshore part of the project, as is the case with Thor OWF.
More details on the project to come in the market dialogue, to be held in the end of November, which the DEA will announce shortly.
Licence for preliminary investigations for Hesselø Offshore Wind Farm
01-10-2020
The Danish Energy Agency (DEA) has today granted Energinet a licence for preliminary investigations for Hesselø Offshore Wind Farm. The licence is valid from the 1st of October 2020 until the 1st of April 2022. As part of the preliminary investigations for the site of Hesselø Offshore Wind Farm, Energinet will conduct preliminary geotechnical, geophysical and marine biological surveys.
The preliminary investigations will take place in the following areas:
- The offshore wind farm area,
- The two options of so-called export cable routes, i.e. the routes that carry the power from the offshore wind farm to the landfall,
- A larger area around the two previously mentioned areas for the marine biological surveys.
Attention is drawn to the fact that the licence for preliminary investigations alone does not allow the construction of Hesselø Offshore Wind Farm and that the DEA has not yet taken a decision on whether it is possible to build a wind farm in the specified area.
The preliminary investigations contribute to the Strategic Environmental Assessment (SEA) of the plan for Hesselø Offshore Wind Farm. The data collected by Energinet during the preliminary investigations will be published on the DEA’s homepage in order to give the tenderers a good basis to prepare their offer later on in the process. This risk minimization is expected to result in lower bid prices and is part of the Danish model for offshore wind tenders. The winner of the tender will also get the possibility to use the results of the preliminary investigations in the Environmental Impact Assessment (EIA) of the offshore-based part of the project.
The licence for preliminary investigations for Hesselø Offshore Wind Farm contains two options regarding the export cable routes: (1) a route from the offshore wind farm to a landfall on the coast near Kyndby (going through Isefjord) and (2) a route from the offshore wind farm to a landfall at Gilbjerg Hoved, west of Gilleleje Harbour. The DEA and Energinet, the Danish TSO, are currently analysing which export cable corridor is the optimal solution, based on a number of parameters such as economics, technology, law, timeframe, environment, etc. The choice of landing route and landing point will be made as soon as possible. Then, only the chosen export cable route will be analysed as part of the preliminary investigations.
In the next couple of months, the DEA and the Environmental Protection Agency (EPA), together with Energinet, will initiate the process for the Strategic Environmental Assessment (SEA) of the plan for Hesselø Offshore Wind Farm as well as the Environmental Impact Assessment (EIA) of the land-based part of the project. The DEA is the responsible authority for the SEA of the plan for Hesselø Offshore Wind Farm while the EPA is the responsible authority for the EIA of the land-based project.
