Dashed tick marks today (13 Oct 2026). The teal diamond on the spine is origination — the seabed award or round that created the project. Every other ownership event 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
RegimeThe farm company's accounts state that Arkona sells its whole output by direct marketing (to Danske Commodities A/S) at the market price and receives the EEG market premium from 50Hertz, topping up to a guaranteed 184 EUR/MWh (18.4 ct/kWh) under EEG 2017 § 19 with § 47 (compressed tariff). The FY2025 accounts say this steps down from September 2026 to 149 EUR/MWh (14.9 ct/kWh). The farm's documents do not state the rate after that stage.
Instrumentmarket premium
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.
