Denmark’s Capability-Based CfD: A Bold Experiment in Offshore Wind Support

Why It Matters

It offers more predictable cash flows, lowering financing costs for offshore projects while reshaping the competitive balance between offshore wind and other renewables in Europe.

Key Takeaways

• Denmark shifts to capability‑based two‑way CfD.
• Scheme ties payments to potential, not actual, output.
• Reduces revenue risk from curtailment and negative prices.
• Implementation risk remains; Belgium similar scheme pending.
• Gives offshore wind advantage over onshore renewables.

Pulse Analysis

Denmark’s offshore wind ambitions hit a snag in 2024 when a 2.8 GW tender collapsed under a pay‑to‑build model that left developers bearing the full market and financing risk. Rising turbine costs, tighter credit conditions and frequent negative day‑ahead prices made the auction unattractive, exposing a gap between policy goals and investor appetite. In response, the Danish Energy Agency rewrote the rules, injecting state support, easing delay penalties and scaling back the volume of projects. This pivot reflects a broader European trend of re‑examining subsidy structures to keep large‑scale renewables bankable.

The centerpiece of the new framework is a capability‑based two‑way CfD, a hybrid that calculates payments on the wind farm’s Available Active Power rather than actual electricity delivered. By using meteorological forecasts to estimate potential output each month, the scheme shields developers from revenue loss when curtailment or negative prices occur, while still requiring them to pay the state if market prices exceed the strike price. The design therefore smooths cash‑flow volatility and can lower the cost of debt, but it also introduces implementation risk, as the methodology has yet to be proven at scale outside a few pilot projects.

If the Danish experiment proves successful, it could reshape offshore wind financing across the EU, offering a template for markets where system operators control grid capacity and curtailment is common. However, the approach gives offshore assets a relative edge over onshore wind and solar, prompting complaints to the European Commission and raising fairness questions. Stakeholders will watch closely as the European Commission evaluates the scheme and as Belgium prepares a similar model for the Princess Elisabeth project. The outcome will influence whether capability‑based CfDs become a mainstream tool for de‑risking renewable investments.
