The European Commission has approved a €5bn Danish support programme aimed at scaling up offshore wind farms, marking a significant step in the EU’s push toward a net-zero energy system by 2030.
The decision enables Denmark to move forward with two major offshore wind energy projects that together could supply roughly a quarter of the country’s annual electricity demand.
The scheme, cleared under the EU’s Clean Industrial Deal State Aid Framework (CISAF) introduced in June 2025, is designed to incentivise long-term investment in renewable infrastructure while maintaining market discipline.
Commenting on the investment, Teresa Ribera, Executive Vice-President for Clean, Just and Competitive Transition, said: “With this €5bn scheme, Denmark will be able to deploy offshore wind capacities faster, in line with the Clean Industrial Deal.
“It will also help Denmark and the EU to reduce their dependence on fossil fuel imports and enhance their renewable energy share, while ensuring that any potential competition distortions are kept to a minimum.”
Two large-scale offshore wind farms planned
At the centre of the programme are two offshore wind farms: Hesselø and North Sea I Mid. Both projects are expected to play a substantial role in Denmark’s renewable energy mix once operational.
The Hesselø installation is projected to deliver at least 0.8 gigawatts (GW) of capacity, producing around 3.2 terawatt-hours (TWh) annually. Meanwhile, North Sea I Mid is expected to reach a minimum capacity of 1 GW, generating approximately 4.6 TWh each year.
Combined, the two offshore wind farms are forecast to produce electricity equivalent to about 25% of Denmark’s total output recorded last year. That scale underlines the strategic importance of offshore wind energy in national and EU-wide decarbonisation plans.
Long-term support mechanism with market safeguards
The Danish scheme will operate over a 20-year period and relies on a two-way contract for difference (CfD) model – a mechanism increasingly used across Europe to stabilise revenues for renewable energy developers.
Under this structure, operators receive financial support when market prices fall below their agreed bid level. Conversely, if electricity prices exceed that level, developers must return the surplus to the Danish authorities. This two-way design is intended to limit windfall profits while protecting investors from price volatility.
Notably, the payments will be based on the theoretical production capacity of the offshore wind farms rather than their actual output. This approach aims to prevent distortions in the electricity market, particularly during periods of negative pricing, aligning the scheme with broader EU electricity market reforms.
Strategic role of offshore wind energy in decarbonisation
The approval reflects a broader trend across Europe, where offshore wind energy is increasingly viewed as a cornerstone of energy transition strategies.
Compared with onshore alternatives, offshore wind farms offer higher and more consistent generation potential, particularly in regions like the North Sea.
Denmark has long been a leader in this sector, and the latest investment reinforces its position while contributing to EU-wide renewable energy targets.
Outlook for deployment
With regulatory approval secured, attention will now shift to project execution and auction processes.
The timeline for construction and commissioning remains subject to tender outcomes and permitting procedures, but the 20-year support provides developers with a stable investment environment.
More broadly, the decision illustrates how coordinated policy frameworks and financial instruments are shaping the next phase of deploying offshore wind farms across Europe.
