Delivery outlook modelled by Hafrok · calibrated on delivered projects

2031
expected year of commercial operation
The developer says 2028; Hafrok expects 2031 — 3 years later.
Chance of delivery
≈74% estimated chance this project reaches commercial operation
Advanced Development projects complete ≈75% of the time on Hafrok's record. A secured offtake contract lifts this one slightly; a market with a thinner delivery record and technical complexity pull a little the other way.

How Hafrok got this date
1
Starting point: the last dated milestone
Consent granted in 2026. From there Hafrok adds how long similar projects (in developing 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 2031.
3
Result
Expected commercial operation 2031, likely range 2029–2031 (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 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 ≈74%, which rates it Expected on Hafrok's four-step delivery scale (Delivering · Expected · Prospective · Fragile).
