Chance of delivery
≈98%
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; a market with a thinner delivery record and technical complexity pull a little the other way.

How Hafrok got this date
1
Starting point: the last dated milestone
Construction start in
2026. From there Hafrok adds how long similar projects (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
2029; the faster quarter of similar projects would be done by 2028, the slower quarter not until 2029 Q3.3
Result
Expected commercial operation
2029, likely range 2028–2030 (the middle half of outcomes for similar projects). The typical build time from the construction start is used.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

Ocean Winds was formed as a 50/50 JV between EDP Renewables (EDPR) and ENGIE to combine their offshore wind assets globally. The JV was announced in 2019 and became operational in mid-2020 following regulatory approvals. The BC-Wind project in Poland (sites B and C) was contributed into Ocean Winds as part of EDPR/ENGIE's combined portfolio (5.5 GW total including 1.5 GW under construction and 4.0 GW under development). No specific financial terms were disclosed for the BC-Wind project specifically. The project had received location permits in 2012 (site B) and 2013 (site C). CfD subsequently awarded June 2021 (PLN 319.60/MWh, 369.5 MW). Financial close for EUR ~2 billion project financing achieved December 2025; construction commenced December 2025; first power expected 2028. In December 2020, Tauron (Polish state utility) signed a 2-year cooperation agreement with Ocean Winds under which Tauron received 50% of Ocean Winds' Polish project companies in exchange for Ocean Winds acquiring 50% of Tauron's Baltic Sea permit companies — however, this arrangement appears to have been unwound before financial close (Ocean Winds is described as 100% owner of BC-Wind at FC). No Tauron exit transaction has been publicly announced or valued.

Dashed tick marks today (9 Sep 2026). 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.

Hafrok counts foundations and turbines from satellite radar images (≈): a structure is counted once it is seen standing in the sea, which is not the same as producing power. A structure first seen in the last 60 days is not yet confirmed, because on a single image a freshly set foundation and a ship holding position look alike. Substation platforms are left out so the counts compare with the number of turbines. Rows marked with a dot (·) come from Hafrok’s own registers; a supplier or contract appears only where a source states it — everything else reads “not recorded”, never guessed.
