Denmark will back its largest offshore wind farm – the up-to 1GW Thor development – with a UK-style contract-for-difference (CfD) in the first use of the mechanism in its build-out programme.

Thor, which will be a minimum of 800MW, will be the first of three large offshore wind projects planned by Denmark by 2030 under its national energy transition plan, agreed last year by politicians from across the spectrum.

Thor, up to 20km offshore in the Danish North Sea, has to be fully online by 2027 and will be Denmark's largest, surpassing the 600MW Kriegers Flak that's due in service in 2021 and 407MW Horns Rev 3, which began operating this year.
