Delivery outlook modelled by Hafrok · calibrated on delivered projects
2033
expected year of commercial operation
The developer says 2031; Hafrok expects 2033 — 2 years later.
Chance of delivery
≈68%
estimated chance this project reaches commercial operation
Advanced Development projects complete ≈75% of the time on Hafrok's record. This one sits well below that: a very large build and technical complexity. A secured offtake contract helps only slightly.

How Hafrok got this date
1
Starting point: the last dated milestone
Consent granted in
2026. From there Hafrok adds how long similar projects (floating, 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
2031; the faster quarter of similar projects would be done by 2029, the slower quarter not until 2032.3
Still needs an offtake award: UK-CFD-AR8
The project has no offtake contract yet. The next visible auction is around
2026 Q4; winners typically reach final investment decision about 2 years after an award (2028 Q4), then build time on top gives 2032 Q4. That is later than the milestone timing, so the auction sets the date.4
Result
Expected commercial operation
2033, likely range 2033–2034 (the middle half of outcomes for similar projects). The developer's announced date (2031) is earlier than similar projects have managed — Hafrok's own date is used and the difference is flagged above.5
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.
6
Chance of delivery — separate from timing
Start from the share of Advanced Development projects that went on to complete — ≈75%, 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). Consented projects have historically completed at very high rates, but the 2023–25 downturn showed consented-but-unfinanced projects can still fail — the estimate holds back for the offtake and financing gates still ahead. Then adjust for this project's own evidence — offtake, market, size, technical complexity — to ≈68%, which rates it

From the auction results — the round that created the project.
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.
Revenue & offtake route to market — open
No offtake secured — route to market open
The routes describe what exists in this market — not a prediction of which the project will take. Timing math for the auction gate lives in the delivery outlook above.
