Under Construction projects complete ≈97% of the time on Hafrok's record. A secured offtake contract lifts this one slightly; its size and technical complexity pull a little the other way.

How Hafrok got this date
1
Starting point: the last dated milestone
Construction start in
2020. From there Hafrok adds how long similar projects (in established offshore-wind markets) took to reach commercial operation, measured on projects that have delivered.2
Typical timing
Starting point plus the typical remaining time gives a middle estimate of
2022; the faster quarter of similar projects would be done by 2021, the slower quarter not until 2023. Dates already in the past are moved up to today — this project has run beyond the typical timing.3
Result
Expected commercial operation
2026, likely range 2025–2027 (the middle half of outcomes for similar projects). The developer's announced date falls inside that likely range, so the announced date is adopted.4
Year-by-year chart
The bars spread that estimate across years using how similar projects actually slipped against their dates — more often late than early, which is why the bars lean right.
5
Chance of delivery — separate from timing
Start from the share of Under Construction projects that went on to complete — ≈97%, measured on Hafrok's record of delivered and abandoned projects, with an allowance held back where that record cannot yet speak (projects still unresolved, changed market conditions). Based on the measured record — all 257 construction starts with a final outcome reached operation — adjusted down for projects still mid-build and for legal-challenge risk. Then adjust for this project's own evidence — offtake, market, size, technical complexity — to ≈98%, which rates it

Eni acquired 20% of Dogger Bank A and B in a single transaction (10% from each of SSE and Equinor). Combined consideration GBP 405m for both phases; per-phase value ~GBP 202.5m. Financial close reached 25 Nov 2020. Converted at GBP/EUR ~1.12 (2020). Eni's stake later transferred to Vårgrønn (Plenitude/HitecVision JV) in Oct 2022.

Intra-group restructuring — not an arm's-length transaction. Plenitude transferred its 20% stake in all three Dogger Bank phases (A/B/C, 3,600 MW combined) to Vårgrønn (65% Plenitude / 35% HitecVision JV). HitecVision increased its Vårgrønn ownership from 30.4% to 35%. See Dogger Bank B and C companion records.

From Hafrok’s transactions record
Dashed tick marks today (9 Sep 2026). The ▲ below the spine is the developer-announced COD. 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.

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.
