Vattenfall took a 60% stake in Horns Rev 1 from Elsam as part of a wider asset swap agreed with DONG Energy on 31 May 2005, completed on 1 July 2006; Elsam's remaining 40% passed to DONG Energy (now Ørsted). No separate price for the Horns Rev stake was published. The DKK 2bn sometimes quoted as the price is what the whole wind farm cost to build.

From Hafrok’s transactions record
Dashed tick marks today (13 Oct 2026). Ownership lives in the band below: one station per recorded deal, dated at its label, in deal order rather than to calendar scale. Secondary trades appear only at the interchanges; grey lines are parties whose entry or exit Hafrok’s record does not hold.
Revenue & offtake the regime the project was built under
Offtake regime on record
RegimePSO feed-in tariff (43 ore/kWh supplement for 10 years, total ~45.3 ore/kWh; then up to 10 ore/kWh to year 20)
InstrumentFiT
A built project sells its power under the contract or support regime it was financed with; it is not expected to bid into new government offtake rounds. Where the record does not yet name that regime, the row says so rather than guessing.
