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
2025 Q3; the faster quarter of similar projects would be done by 2024 Q4, the slower quarter not until 2026 Q3. Dates already in the past are moved up to today — this project has run beyond the typical timing.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

Yushan Energy → Mitsui & Co. stake not disclosed

- Project stage
- early development
In August 2018, Mitsui & Co. (Japan) acquired a 50% stake in Yushan Energy Taiwan Co., the Taiwanese subsidiary of Singapore-based Yushan Energy, which holds 40% of the Hai Long offshore wind project (both Hai Long 2 and Hai Long 3). The effective result was that Mitsui acquired a 20% indirect interest in the combined Hai Long project (50% × 40% = 20%). Post-transaction ownership of the Hai Long project: Northland Power 60%, Yushan Energy 40% (of which Mitsui holds 50% of Yushan Energy Taiwan, = 20% effective; Enterprize Energy holds 50% of Yushan Energy Singapore). The Mitsui entry covered the combined 1,022 MW Hai Long project (both phases). Transaction value not publicly disclosed. This record covers Hai Long 2 (518 MW per FK). The Mitsui entry represents Japan's first investment in a Taiwan offshore wind project. Data confidence: MEDIUM — effective stake and structure confirmed; deal value undisclosed.

On 14 December 2022, Northland Power announced a strategic partnership with Gentari International Renewables Pte. Ltd. (a Petronas subsidiary focused on clean energy) under which Gentari would acquire 49% of Northland's ownership interest in the Hai Long offshore wind project (both Hai Long 2 and Hai Long 3, combined 1,022 MW). The transaction closed on 28 December 2023. Consideration: approximately NT$18 billion (CAD 0.8 billion, approximately EUR 556 million). Post-transaction ownership: Northland Power ~30.6% (60% × 51%), Gentari ~29.4% (60% × 49%), Yushan Energy (Mitsui/Enterprize) 40%. The proceeds were used to repay CAD 500 million of Northland's short-term corporate credit facility and fund remaining equity in the project. Hai Long's total project cost was approximately CAD 9 billion, with CAD 5 billion project finance debt signed in September 2023. COMBINED DEAL: CAD 800m = EUR 556m total for both Hai Long 2 + Hai Long 3. Capacity-weighted allocation: Hai Long 2 (518 MW) / 1,022 MW = 50.7% → EUR 282m for this record. Hai Long 3 companion record shows EUR 274m (49.3%). These are notional allocations — Northland's disclosure does not disaggregate. Data confidence: HIGH — deal value confirmed by Northland press release. EUR figure at the ECB 2022-12 monthly average (0.6955 EUR per CAD).
