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.

How Hafrok got this date
1
Starting point: the last dated milestone
Consent granted in
2024. 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
2028; the faster quarter of similar projects would be done by 2026, the slower quarter not until 2029.3
Result
Expected commercial operation
2030, likely range 2026–2029 (the middle half of outcomes for similar projects). The developer's announced date falls inside that likely range, so the announced date is adopted.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 ≈81%, which rates it

Founding JV · 2024-06
Vattenfall · Copenhagen Infrastructure Partners — Zeevonk consortium (Vattenfall and Copenhagen Infrastructure Partners via CIP Energy Transition Fund) awarded the permit for the 2 GW IJmuiden Ver Beta site on 11 June 2024. Project later split: Phase 1 (1 GW) targeted for 2029; Phase 2 (1 GW) delayed to 2032 following Delta Rhine Corridor grid delay. Total permit fee originally EUR 800m, reduced to EUR 400m following delays. Project includes 50 MWp floating offshore solar and large-scale electrolyser at Maasvlakte. No secondary stake sales identified to date.
Evidence
From the auction results — the round that created the project; founding JV from Hafrok’s transactions record.
Dashed tick marks today (9 Sep 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.
