Description of the subsidy scheme for Hesselø OWF
Publication of the scoping of the strategic environmental assessment (SEA) for the plan for Hesselø Offshore Wind Farm
In the period from 12 February to 19 March 2021, the Danish Energy Agency (DEA) conducted a public hearing to obtaining comments and proposals for the scoping of the strategic environmental assessment (SEA) for the plan for Hesselø Offshore Wind Farm. Based on the inputs received during the consultation, the DEA has now adjusted the scoping compared to the draft version that was published as part of the consultation material. The scoping contains the DEA’s requirements for the environmental report, including which topics and environmental impacts must be highlighted in the report and how comprehensive and detailed information the report must contain.
During the second quarter of 2021, the DEA expects also to publish a consultation note, which will contain a description of the inputs received together with the DEA's comments. It will also include a description of how the inputs received were included in the further environmental assessment process.

There are a few adjustments to the scheme. Please find the agreement on the subsidy scheme here – in Danish only.
A thorough description of the subsidy scheme in English will follow soon.
The Danish energy Agency and energinet provide access to data from the preliminary investigations for Hesselø Offshore Wind Farm
In relation to the tendering of Hesselø OWF, a range of preliminary investigations and environmental assessments are being carried out. The Danish Energy Agency and Energinet are now providing access to the first results and data from these investigations.
Here is the link to the new webpage about preliminary investigations: https://ens.dk/en/our-responsibilities/wind-power/ongoing-offshore-wind-tenders/hesselo-offshore-wind-farm/preliminary
Results in the form of reports and data will be updated continuously on this webpage, as soon as they are ready. An overview of all the results and data to be collected, as well as approximate times for when these will be available can also be found on the webpage.
The information in the reports and data is primarily aimed at potential tenderers for Hesselø OWF, but the environmental reports are also relevant for stakeholders in relation to the environmental assessments process.
The Danish Energy Agency and the Danish Environmental Protection Agency launches a 5-week public hearing concerning environmental assessments related to Hesselø Offshore Wind Farm
The Danish Energy Agency and the Danish Environmental Protection Agency invites the public, companies, authorities and other interested in the coming Hesselø Offshore Wind to submit ideas on the strategic environmental assessment (SEA) for the plan for Hesselø Offshore Wind Farm and the environmental impact assessment (EIA) of the land-based part of the project.
The public hearing, which is an early public consultation in the scoping phase, runs from the 12 February to 19 March 2021.
The Danish Energy Agency is the responsible authority for the SEA of the plan for Hesselø Offshore Wind Farm while the Danish Environmental Protection Agency is the responsible authority for the EIA of the land-based project. Based on the ideas and inputs received during the consultation, the Danish Energy Agency and the Danish Environmental Protection Agency will decide what topics and environmental impacts to be included in the SEA and the EIA respectively.
The results of the environmental assessments should be published and subject to a public consultation in the first half of 2022. The Danish Environmental Protection Agency expects mid-2022 to issue the EIA-permit (§ 25 of the Danish Environmental Assessment Act) for the land-based part of the project.
The EIA of the offshore-based part of the project is expected to be carried out in 2023-2024 when the winner of the tender for Hesselø Offshore Wind Farm has been found: the scoping phase is expected to be in 2023 and the 2nd public consultation on the EIA report is expected to be in 2024. Later in 2024, 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.
Publication of the market dialogue material for the future Hesselø Offshore Wind Farm tender
Today, the DEA publishes the discussion paper for the market dialogue regarding the upcoming Hesselø OWF tender. The DEA would thereby like to invite potential tenderers and relevant industry associations to participate in the market dialogue by sending written input and/or by participating in a virtual meeting with the DEA and the Danish TSO, Energinet.
- Written comments and questions to the DEA should be sent by e-mail to email@example.com by no later than 7 December 2020.
- The virtual meetings will take place on 25, 26, 27 and 30 November 2020.
Market dialogue on the tendering process
The market dialogue on the tendering procedure for Hesselø OWF will be held on 25 - 30 November, 2020.
More info and how to sign up for bilateral meetings with the DEA and Energinet will follow.
Gilbjerg Hoved chosen as landfall for Hesselø grid connection
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
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.
