estimated chance this project reaches commercial operation
Advanced Development projects complete ≈75% of the time on Hafrok's record. A secured offtake contract puts this one well above that; a market with a thinner delivery record and technical complexity weigh only slightly against it.

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
Result
Expected commercial operation
2031, likely range 2030–2033 (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 ≈82%, which rates it

- Awarded to
- EDF Renouvelables + Maple Power
- Basis
- integrated tender
Founding JV · 2024-12
EDF Renewables · Maple Power — The French government awarded the AO6 Mediterranean floating wind tender to a consortium of EDF Renewables and Maple Power (50-50 JV of Enbridge Inc. and CPP Investments) for the Golfe de Fos zone in December 2024. The project company is named Eoliennes Méditerranée Grand Large and is located approximately 25 km off Fos-sur-Mer (Bouches-du-Rhône), covering 52 km2. BW Ideol is the technology partner, providing concrete floating foundation design (Damping Pool technology) based on a collaboration agreement signed in 2022. No consideration was exchanged between parties at this stage; this was a tender consortium formation. The project is expected COD around 2031 and will supply approximately 450,000 residents.

- Project stage
- early development
BW Ideol Projects Company (a subsidiary of BW Ideol, itself part of BW Group) became a shareholder in Eoliennes Méditerranée Grand Large in November 2025, acquiring a 15% equity stake from EDF Renewables. BW Ideol's investment reflects its dual role as both technology licensor (providing the Damping Pool concrete floating foundation design) and equity co-investor. No consideration was publicly disclosed; the entry of a technology partner as equity co-investor is unusual and suggests a technology-in-kind or discounted equity arrangement rather than a cash transaction. Post-entry ownership: EDF Renewables + Maple Power (combined 85% split between them), BW Ideol 15% (exact EDF/Maple split not publicly confirmed). The project remains in the development phase (COD ~2031).

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.
