Danish 1.8 GW offshore auction clears after CfD redesign rescues tender

Denmark's 1.8 GW offshore tender has closed successfully after the energy agency overhauled its auction design. The prior round offered uncapped negative bidding and attracted no participants. This cycle replaced that mechanism with two-sided Contracts for Difference, giving developers both a price floor and a ceiling. WindEurope says the result demonstrates that auction structure, not market appetite, was the constraint.

Competition was sharp despite the design fix. Recharge News reports that Vattenfall described its own strategy as bidding 'aggressively' with the explicit goal of shutting out rivals. That posture points to genuine developer demand for Danish seabed rights once the revenue-risk profile became manageable under the CfD framework.

The outcome adds a concrete data point to the wider European debate over support mechanisms. Two-sided CfDs are already the reference instrument in the UK and several Nordic markets. Denmark's failed-then-succeeded sequence gives regulators elsewhere a direct before-and-after comparison on how negative-bidding exposure suppresses participation.
