Evidence
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
RegimeROC (banding uncertain — likely 1.5 ROC/MWh; first power Sep 2009)
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.
Installation how the build is going · from satellite counts and Hafrok’s registers
Satellite survey
the farm as it stands, counted from satellite radar images · built before the count began, so there is no build to chart
Satellite survey
Structures standing59≈58 turbines + 2 platforms expected · 1 fewer than expected — a position the survey missed

Built2008 → 2010-04offshore construction to start of operation, from the record
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.

Offshore substationRobin Rigg East offshore substation platform·under construction · owner E.ON Climate & Renewables (UK) Ltd at construction; today RWE Renewables UK Robin Rigg East Limited. THE PLATFORM WAS NOT SOLD TO THE OFTO — it was excluded from the transfer perimeter and retained by the generator. This is the exception in the British fleet, so the usual "the current owner is the OFTO" shortcut fails here.
