Delivery outlook modelled by Hafrok · calibrated on delivered projects
2034
expected year of commercial operation
The developer says 2029; Hafrok expects 2034 — 5 years later.
Chance of delivery
≈60%
estimated chance this project reaches commercial operation
Early Development projects complete ≈61% 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
No dated milestone yet
Nothing is consented or financed with a date, so the estimate starts from today (
2026), adds the time similar projects (in developing offshore-wind markets) took from consent to operation, plus an allowance for obtaining consent.2
Earliest credible date
Typical consent-to-operation time plus allowances means commercial operation before
2034 is not credible.3
Still needs an offtake award: KR-OFFSHORE-2026H2
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 2031 Q4. The milestone timing is already later than that, so it stands.4
Result
Expected commercial operation
2034, likely range 2034–2039 (the middle half of outcomes for similar projects). With no milestone to build from, the earliest credible date is the estimate, with a deliberately wide range.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 Early Development projects that went on to complete — ≈61%, 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). About three in four early-stage projects with a final outcome went on to operate — a record from an easier era. Most of today's early pipeline is still unresolved, so the estimate discounts it. Then adjust for this project's own evidence — offtake, market, size, technical complexity — to ≈60%, which rates it

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.
