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
RegimeThe farm company's FY2016 accounts book its revenue as EEG market premium (EUR 218.5m in 2016, 174.0m in 2015) plus EEG power delivered (EUR 34.8m; 32.0m), with service fees for power marketing in its costs, and state that it elected the EEG compressed tariff model (Stauchungsmodell). The accounts do not state the tariff rate.
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.
