Vidar
Floating energy park in the northern Skagerrak, ~35 km from the mainland and ~25 km west of Väderöarna, within the Swedish EEZ (price area SE3); 201 km², water depths ~100–330 m so floating foundations throughout.

estimated chance this project reaches commercial operation
Advanced Development projects complete ≈75% of the time on Hafrok's record. This one sits well below that: a market with a thinner delivery record, a very large build, technical complexity and no offtake contract yet.

How Hafrok got this date
1
Starting point: the last dated milestone
Consent granted in
2026. From there Hafrok adds how long similar projects (floating, 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
2032; the faster quarter of similar projects would be done by 2030, the slower quarter not until 2032 Q3.3
No route to market yet — counted from 2029
The project has no offtake contract yet. No contract, auction or tariff exists in Sweden today that a project without an offtake agreement could win, and none is scheduled. Hafrok believes a first support award there is unlikely before
2029 Q3, and counts from then. This is Hafrok's judgment, not a fact on the record — what it rests on: Sweden market page. The permits are not affected; winners typically reach final investment decision about 2 years after an award (2031 Q3), then build time on top gives 2035 Q3. That is later than the milestone timing, so the auction sets the date.4
Result
Expected commercial operation
2035, likely range 2034–2037 (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 ≈59%, which rates it
