estimated chance this project reaches commercial operation
Advanced Development projects complete ≈75% of the time on Hafrok's record. This one sits below that: its size 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
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; the faster quarter of similar projects would be done by 2027, the slower quarter not until 2030.3
Still needs an offtake award: NL-IJMUIDEN-VER-GAMMA-A
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. That is later than the milestone timing, so the auction sets the date.4
Result
Expected commercial operation
2032, likely range 2032–2033 (the middle half of outcomes for similar projects). The developer's announced date falls inside that likely range, so the announced date is adopted.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 ≈73%, which rates it
Expected on Hafrok's four-step delivery scale (Delivering · Expected · Prospective · Fragile).Project timeline verified milestones only — each date carries its provenance mark

Revenue & offtake route to market — open
No offtake secured — route to market open
No tender held. Applications for permit expected 26 November - 10 December 2026. Maximum subsidy raised to EUR 0.116/kWh (from EUR 0.103/kWh) under TOWOZ, the Dutch temporary offshore wind subsidy scheme. Combined subsidy budget for Gamma-A and Gamma-B raised to EUR 9.456 billion (from EUR 7.896 billion). ◇
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.
