The Danish Energy Agency and the Environmental Protection Agency launches a 5-week public hearing concerning environmental assessments related to Thor Offshore Wind Farm


The DEA and the EPA launches a 5-week hearing concerning the Strategic Environmental Assessment (SEA) of the plan for Thor Offshore Wind Farm as well as the Environmental Impact Assessment (EIA) of the land-based part of the project, which is to be built by Energinet, the Danish TSO. The public hearing, which is an early public consultation in the scoping phase, runs from 24th April to 12 noon 29th May 2020. As part of the hearing, approximately 5,600 local landowners and relevant organizations have received a letter concerning the hearing. All relevant hearing material, information on how to submit inputs to the hearing, etc. is available. Find the material (in Danish). The Environmental Impact Assessment (EIA) of the offshore-based part of the project will take place in the period 2022-24, when the winner of the tender for establishing Thor Offshore Wind Farm has been appointed. The DEA is the responsible authority for the SEA of the plan for Thor Offshore Wind Farm while the EPA is the responsible authority for the EIA of the land-based project.

The Danish Energy Agency publishes notice on Thor-tender on EU Tenders Electronic Daily (TED)


The Danish Energy Agency has today published a so-called prior information notice on EU´s platform for public procurement, Tenders Electronic Daily (TED). The purpose of this notice is to inform the market as widely as possible about the forthcoming tendering of Thor Offshore Wind Farm.

The notice is non-binding, and is primarily an opportunity for market players to make adequate preparations for the forthcoming tendering process. The notice will be followed by a binding contract notice, which officially will launch the tendering process and pre-qualification process. The publication of the contract notice together with the complete tender conditions is planned for Q3 2020.

The prior information notice informs about a range of important details such as the size and nature of the project, contract value, geographical location, subsidy scheme, pre-qualification criteria, etc. These details play an important role for who will be able to bid for Thor, and who wish to participate in bidding for Thor. In case some bidders wish to, or see it necessary to, form consortia or use certain suppliers, one of the main aims of the prior information notice is for them to start the building of such necessary consortia.

Together with the prior information notice, a set of supporting documents are published on the tendering process, participation in the tender, the subsidy scheme and award criteria as well as an overview of all available background material on the tender.

The prior information notice and supporting documents for the tender

Q&A concerning the prior information notice open until 24 April 2020

It is possible to raise written questions to the prior information notice for a limited period of time until 24 April 2020 by sending any questions to Questions and answers will be published ongoing on the Thor website.

New timing of the grid connection for Thor offshore wind farm


As outlined in the Energy Agreement of 2018, Thor shall be grid connected in the period 2024-2027.

As part of the market dialogue held on Thor,  a majority of market players made it clear that they would not be able to grid connect Thor until Q1 2025, thus emphasizing that the planned grid connection for Q2 2024 would be needless.  In order to optimize the possibilities for cost savings, it has been decided to provide the Danish TSO, Energinet, with the flexibility to adjust the grid connection to Q1 2025, should this be the most advantageous considering the need for connecting land based renewable production capacity to the grid (see also related news on selecting northern landfall for Thor the grid connection).

The adjustment of the grid connection does not change the overall plans for Thor, which is scheduled to be fully commissioned by the end of 2027.

Thor and any Danish CO2-reductions will not be delayed, and the adjustments to the time-table is purely a direct consequence of the market dialogue. The market dialogue had a primary objective of ensuring that the tender conditions provide the lowest possible bid prices and thus the lowest possible cost for the green transition of the Danish economy. Adjustments based on input from the market dialogue has been an explicit principle in the political negotiations about the tender, and is a central element of the Danish model for offshore wind, which has proved its worth in this situation.

Northern landfall selected for Thor grid connection


Energinet and the Danish Energy Agency has decided that the export cables from Thor Offshore Wind Farm will have its landfall at Tuskær north of Nissum Fjord. Accordingly, the possibility for a landfall south of Nissum Fjord has been cancelled.

This decision is primarily based on considerable cost savings to be realized by grid connecting north of Nissum Fjord, where the planned nearshore substation can serve both the Thor grid connection and up to 400 MW PV-solar installations planned in the area. Thus, the substation will serve 1.400 MW installed renewable energy.

In addition to this, the preliminary environmental site-investigations has proved that there are certain environmental advantages for using the northern landfall. Fewer landowners and neighbors will be affected. There will be fewer archaeological occurrences. The need for crossing streams will be smaller, and shorter stretches with forest etc. will be affected. Finally, a parcel has been identified in the north, where the view to the substation will be limited, while a substation located in the south would cause more disturbance in terms of the landscape and proximity to neighbors. 

The Danish Energy Agency publishes answers raised in the market dialogue on Thor Offshore Wind Farm


To follow up on the market dialogue on Thor Offshore Wind Farm held in November 2019, the Danish Energy Agency now publishes answers to questions raised as part of the dialogue on the tender procedures.

The published questions and answers clarify a range of issues in the tender, hereunder about the time-table, the process for environmental assessments, the subsidy scheme, the capacity for the wind farm, the grid connection, prequalification, etc.:

Baseline surveys regarding marine bird distribution at the Thor site


Study 1: Number and distribution of birds in and around two potential offshore wind farm areas in the Danish North Sea and Kattegat (DCE, 2019)

The Danish Energy Agency requested a total of ten surveys of birds conducted in two areas of interest in the North Sea and in Kattegat, five surveys in each area. The surveys were conducted as aerial line transect surveys from December 2018 until April 2019. This publication reports the findings of the surveys. Relevant bird species for each of the two areas are described, and thematic maps are presented.

Number and distribution of birds – DCE Report 2019

Study 2: Site selection for offshore wind farms in Danish waters Investigations of bird distribution and abundance (DHI, 2019)

In connection with the Danish Energy Agency's screening for new areas for development of offshore wind farms, four gross areas have been identified for the upcoming 800 MW offshore wind farms, consisting of the areas Thor/Ringkøbing (North Sea), Jammerbugt, Hesselø and Krieger’s Flak. As part of the screening, this report provides reviews and analyses of existing knowledge of bird occurrence in the four areas with the aim to strengthen the basis for decision-making for the location of future offshore wind farms. The key species investigated in the four areas are: Ringkøbing/Thor and Jammerbugt: Red-/Black-throated Diver, Common Scoter.
