Denmark has awarded two major offshore wind parks to Vattenfall at guaranteed strike prices of DKK 504 and 542 per megawatt hour, locking taxpayers into up to DKK 55.2 billion of support over 20 years. The move follows the spectacular collapse of a zero-subsidy tender model in 2024.
The announcement this week marks a dramatic reversal for a country that once boasted offshore wind would pay for itself. Instead of developers paying the state for concessions, the state now underwrites their revenue risk through two-sided contracts for difference.
That deal runs for exactly 20 years from commissioning, which must happen by 2032. During that period, the state tops up payments when wholesale prices fall below the strike price. But it also claws back money when prices rise above it, a mechanism the Energy Agency calls a kapacitetsbaseret differencekontrakt.
Why the Old Model Failed
The previous tender offered six offshore sites on the assumption that technology cost falls and rising electricity prices would make projects profitable without subsidy. Developers were expected to bid negative numbers, effectively paying for the privilege to build.
By December 2024, three of those six areas had received zero bids. Industry figures blamed interest rate hikes, turbine cost inflation, and supply chain pressures. Kristian Jensen of Green Power Denmark told Maritime Danmark that projects simply could not be made to work financially under the old rules.
The UK faced similar failures in its 2023 offshore wind round when strike prices around GBP 44 per megawatt hour in 2012 prices failed to attract any takers. Denmark’s new accepted bids of DKK 504 and 542 per megawatt hour reflect how far cost assumptions have shifted in two years.
What Taxpayers Are Now On the Hook For
The total public support cap across all three planned parks is DKK 55.2 billion including VAT. That works out to roughly DKK 9,000 per resident or DKK 21,000 per average household over two decades, using 2025 population data.
Nordsøen Midt drew two bids and Hesselø attracted five, a stark contrast to the empty envelope outcome 18 months earlier. Both parks are now awarded to Vattenfall subsidiaries and together will form part of a 2.8 gigawatt package.
The third park, Nordsøen Syd, remains open with a bid deadline in October 2028. That pushes final support commitments well beyond the current government’s term and into the next decade’s fiscal planning.
Revenue Risk Runs Both Ways
Unlike older one-way feed-in tariffs, the new CfD model makes producers pay the state when wholesale prices exceed the strike price. That design aims to protect public finances during price spikes, but critics question whether consumers will see lower bills or whether surplus revenue simply flows into general budgets.
The Energy Agency’s tender documents spell out that the contract price adjusts for inflation and producers must indbetale forskellen til staten when market references rise. This creates a long-term fiscal exposure window stretching to around 2052, the year the first 20-year CfD expires.

Deputy Director Stig Uffe Pedersen described the award as a vital milestone after months of uncertainty. Then Climate Minister Lars Aagaard had earlier warned Denmark could not afford more empty envelopes when he announced the policy shift in January 2025.
Impact on Internationals and the Workforce
For residents and businesses in Denmark, including internationals, the practical effects will show up in transmission tariffs overseen by Energinet and the Utility Regulator. Households and small firms can track regulatory changes through English language summaries published by those agencies.
The offshore wind supply chain typically creates thousands of construction, operations, and port service jobs over project build-out. As of 2023, the most recent year with published figures, around 14 to 15 percent of people employed in Denmark’s electricity and gas supply sector were foreign nationals or immigrants according to Statistics Denmark.
Vattenfall is Swedish state-owned, and the award underscores how offshore wind investment in Denmark increasingly depends on Nordic cross-border integration. That matters for internationals working across regional labour markets under EU free movement rules.
Residents near planned grid connections in Jutland and Zealand can participate in public hearings on environmental impact assessments and transmission line routing. Some consultation documents are Danish only, but English contact points are available on request from Energistyrelsen and municipal planning portals.
Denmark’s Place in the European Wind Race
Denmark already generated around 57 to 60 percent of its power from wind and solar combined as of 2023, according to Eurostat. That compares with roughly 30 to 35 percent in Germany and 25 to 30 percent across the EU-27 average in the same year.
The shift to CfD-backed projects mirrors failed auctions across Europe between 2023 and 2024, when inflation and financing costs upended zero-subsidy expectations in the UK and Germany. Denmark is now competing for capital with those markets plus the United States, where subsidies under the Inflation Reduction Act have tilted investment flows.
As more offshore capacity links to German and Dutch grids via interconnectors, wholesale price dynamics and CfD settlements will depend increasingly on cross-border flows. EU state aid rules and the Electricity Market Regulation will constrain how much Denmark can adjust its support schemes in future, tying domestic policy to Brussels frameworks.
The parks must be operational by 2032. That gives Vattenfall just over five years to navigate permitting, supply chain bottlenecks, and grid connection approvals. For internationals in Denmark, the timeline sets a clear window for job opportunities, regulatory engagement, and electricity price developments tied to the largest single public support commitment in Danish energy policy in years.
