Delivery outlook modelled by Hafrok · calibrated on delivered projects
2029
expected year of commercial operation
The developer says 2028; Hafrok expects 2029 — 1 year later.
Chance of delivery
≈95%
estimated chance this project reaches commercial operation
Financed projects (investment decision taken) complete ≈92% of the time on Hafrok's record. A secured offtake contract lifts this one above that; its size and technical complexity pull the other way.
COD outlook
If it completes, when — Hafrok’s probability by year (teal)
| Year | Probability |
|---|---|
| 2028 | 6.3% |
| 2029 (expected) | 72.3% |
| 2030 | 20.3% |
| 2031 | 1.0% |
How Hafrok got this date
1
Starting point: the last dated milestone
Final investment decision in
2026. 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 2028 Q3, the slower quarter not until 2030 Q2.3
Result
Expected commercial operation
2029, likely range 2029–2030 (the middle half of outcomes for similar projects). The developer's announced date (2028) is earlier than similar projects have managed — Hafrok's own date is used and the difference is flagged above.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 Advanced Development (FID) projects that went on to complete — ≈92%, 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). Financed projects have essentially always gone on to operate, but few have resolved since taking their investment decision — the estimate holds just below the construction-stage level rather than claiming certainty from a thin record. Then adjust for this project's own evidence — offtake, market, size, technical complexity — to ≈95%, which rates it
