E.ON's 50% transferred to RWE as part of E.ON/RWE/Innogy asset swap. Not arm's-length; no project-level consideration. RWE subsequently held 50%. Announced March 2018, completed October 2019.

Equinor sold 25% (half of its 50% holding) to Energy Infrastructure Partners (EIP, formerly Credit Suisse Energy Infrastructure Partners) for EUR 500m. Implies 100% project equity value of EUR 2.0bn and EUR 5,195/MW — above operational high end (EUR 4.5M). Premium partially explained by EEG feed-in tariff (pre-2017 project, commissioned 2019) and tight 2019 market for operational offshore wind equity. Post-close: RWE 50%, Equinor 25%, EIP 25%.

From Hafrok’s transactions record
Dashed tick marks today (9 Sep 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
RegimeEEG Stauchungsmodell (para. 47 Abs. 3 EEG): 19.40 ct/kWh for years 1-8, then 15.40 ct/kWh for years 9-14, then 3.90 ct/kWh thereafter. Qualifies for extended period as site is more than 12 NM offshore and in water depth greater than 20 m.
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.

Hafrok counts the structures standing in the sea from satellite radar images (≈) and reads the count against the turbines and platforms on record. The farm was built before this count began, so the images show it complete; they cannot date its construction. Rows marked with a dot (·) come from Hafrok’s own registers.
