Delivery outlook modelled by Hafrok · calibrated on delivered projects
2032
expected year of commercial operation
The developer says 2030; Hafrok expects 2032 — 2 years later.
Chance of delivery
≈80%
estimated chance this project reaches commercial operation
Advanced Development projects complete ≈75% of the time on Hafrok's record. A secured offtake contract puts this one well above that; its size and technical complexity weigh only slightly against it.
COD outlook
If it completes, when — Hafrok’s probability by year (teal)

How Hafrok got this date
1
Starting point: the last dated milestone
Consent granted in
2025. 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
2029 Q2; the faster quarter of similar projects would be done by 2027 Q3, the slower quarter not until 2030 Q3.3
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 Q1. That is later than the milestone timing, so the auction sets the date.4
Result
Expected commercial operation
2032, likely range 2031–2033 (the middle half of outcomes for similar projects). The developer's announced date (2030) 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 ≈80%, which rates it

RWE confirmed completion of the divestment of its 33.33% share in Five Estuaries to EDF on 8 October 2026; as a result of the sale EDF will take over responsibility for leading the project on behalf of the joint venture partners. Consideration undisclosed. The earlier announcement of the sale agreement is not held, so the completion release dates the row.
Evidence
From Hafrok’s transactions record
Dashed tick marks today (13 Oct 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.
