From Hafrok’s transactions record
Dashed tick marks today (9 Sep 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
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 installation tracker
counted from satellite radar images · a structure standing in the sea on a given date, not a turbine producing power · a guide, not a sourced fact

Hafrok counts foundations and turbines from satellite radar images (≈): a structure is counted once it is seen standing in the sea, which is not the same as producing power. A structure first seen in the last 60 days is not yet confirmed, because on a single image a freshly set foundation and a ship holding position look alike. Substation platforms are left out so the counts compare with the number of turbines. Rows marked with a dot (·) come from Hafrok’s own registers; a supplier or contract appears only where a source states it — everything else reads “not recorded”, never guessed.
Structures standing over time · count
strong line = confirmed · light line = seen in the last 60 days, not yet confirmed · the chart counts every structure (31 turbines + 2 platforms); the table counts turbines only
