estimated chance this project reaches commercial operation
Under Construction projects complete ≈97% of the time on Hafrok's record. A secured offtake contract lifts this one slightly; its size and technical complexity pull a little the other way.

How Hafrok got this date
1
Starting point: the last dated milestone
Construction start 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
2026; the faster quarter of similar projects would be done by 2025, the slower quarter not until 2027.3
Result
Expected commercial operation
2027, likely range 2025–2027 (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 Under Construction projects that went on to complete — ≈97%, 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). Based on the measured record — all 257 construction starts with a final outcome reached operation — adjusted down for projects still mid-build and for legal-challenge risk. Then adjust for this project's own evidence — offtake, market, size, technical complexity — to ≈98%, which rates it

Gentari acquired 49% of Northland Power's ownership in the combined Hai Long project (Hai Long 2 + Hai Long 3, 1,022 MW) for approximately NT$18 billion (CAD 800 million = EUR 552 million at 2023 CAD/EUR 0.69). This record covers the Hai Long 3 (504 MW) portion of the deal. See Hai Long 2 companion record for full deal context. COMBINED DEAL: CAD 800m = EUR 552m total for both Hai Long 2 + Hai Long 3. Capacity-weighted allocation: Hai Long 3 (504 MW) / 1,022 MW = 49.3% → EUR 272m for this record. Hai Long 2 companion record shows EUR 280m (50.7%). These are notional allocations — Northland's disclosure does not disaggregate. Post-transaction: Northland ~30.6%, Gentari ~29.4%, Yushan Energy (Mitsui/Enterprize) 40%. Data confidence: HIGH — deal value confirmed by Northland press release.
