The BC-Wind Offshore Wind Farm is progressing through construction, with onshore cable-route works completed and port infrastructure preparing for offshore installation. Ocean Winds began leasing Poland’s Świnoujście Offshore Terminal in September 2026 to support foundation and transition-piece logistics. Meanwhile, the developer has advanced construction of its operations and maintenance base in Władysławowo, with Przembud Gdańsk appointed as general contractor. The 390 MW offshore wind project lies approximately 23 kilometres off Poland’s Pomeranian coast and targets first power in 2028.
The project reached financial close in December 2025, securing approximately €2 billion to support construction. Its development includes 26 Siemens Gamesa turbines, offshore foundations, electrical infrastructure, export cables and an onshore grid connection. In August 2026, Ocean Winds confirmed completion of three horizontal directional drilling crossings along the onshore export cable route. The work cleared obstacles beneath a coastal dune, a swamp and archaeological sites, allowing the next stage of cable installation to proceed.
BC-Wind Offshore Wind Farm: $2.3 Billion Project Advances Toward 2028 Start-Up
The BC-Wind Offshore Wind Farm is advancing its construction programme, with onshore cable-route preparation completed and port infrastructure moving towards offshore installation. Ocean Winds began leasing the Świnoujście Offshore Terminal in September 2026 to handle foundations and transition pieces for the Polish Baltic Sea development. The developer also broke ground on an operations and maintenance base in Władysławowo in September. The 390 MW project lies approximately 23 kilometres off Poland’s Pomeranian coast and targets first power in 2028.
The project secured approximately €2 billion in financing in December 2025, equivalent to around $2.3 billion. It will feature 26 Siemens Gamesa turbines rated at 14 MW each, alongside offshore foundations, electrical infrastructure and export cables. In August 2026, the developer confirmed completion of three horizontal directional drilling crossings along the onshore export cable route. These crossings pass beneath a dune and road, archaeological sites, and a swamp, limiting disruption to sensitive areas.
BC-Wind Offshore Wind Farm Advances Onshore Infrastructure
P&Q, the onshore grid connection contractor, has completed service-road preparation for the 275 kV cable line. The company also completed the three horizontal directional drilling crossings required along the export cable route. TELE-FONIKA Kable will manufacture the onshore power cables at its Bydgoszcz plant. Once installed, these cables will connect the offshore wind farm to Poland’s electricity network.
Ocean Winds has appointed Przembud Gdańsk as the general contractor for the Władysławowo operations and maintenance base. Construction began in September 2026, with completion expected by the end of 2027. The two-storey facility will provide office, storage and operational space to support the wind farm throughout its operating life. Furthermore, Hydrobudowa Gdańsk will modernise the port quay to accommodate project-related activities.
BC-Wind Offshore Wind Farm Prepares for Offshore Installation
Ocean Winds began leasing the Świnoujście Offshore Terminal in September 2026 under an arrangement running through the fourth quarter of 2027. The facility will support the handling, storage, preparation and loading of offshore foundations and transition pieces. Ocean Winds has also engaged Team Project to prepare and level the terminal area for component-handling operations.
The offshore foundation package will comprise 27 monopiles and transition pieces, covering 26 turbines and the offshore substation. Monopile installation is planned for late in the first quarter and early in the second quarter of 2027. Transition-piece installation is scheduled for the third and fourth quarters of 2027. Meanwhile, Cadeler holds the contract to transport and install the 26 Siemens Gamesa turbines, with installation planned for 2028.
Poland’s offshore construction pipeline also includes the Baltica 2 Offshore Wind Project, where PGE and Ørsted have appointed BGB Group to provide scaffolding and specialist construction support across four offshore substations. The appointment highlights the importance of temporary access systems, cable work and commissioning support alongside major offshore installation packages. Read more about the Baltica 2 Offshore Wind Project and BGB Group’s construction-support appointment.
BC-Wind is expected to supply renewable electricity to nearly 500,000 Polish households annually. Its delivery now depends on coordinating onshore cable installation, port readiness, foundation installation, offshore electrical infrastructure and turbine deployment. The project’s first power remains scheduled for 2028.
Updated December 1, 2025
Ocean Winds’ first offshore wind farm in Poland, BC-Wind has secured €2 billion in project financing, officially greenlighting the construction phase. BC-Wind will feature a 390 MW bottom-fixed wind farm in the Baltic Sea that aims to deliver renewable power to nearly 500,000 Polish households. The farm is located about 23 km off the coast of Pomeranian Voivodeship near the Krokowa-Choczewo municipalities.
It will use twenty six 14 MW turbines, and is set for first power delivery by 2028. BC-Wind project construction work will start with the design and development of the onshore substation and export cable route. This will be carried out by the Polish company P&Q and Tele-Fonika Kable in 2026. The €2 billion project financing is also underpinned by domestic supply chain contracts and a substantial backing from the European Investment Bank (EIB). Though not ranked amongst the largest offshore wind farms in Europe the project will still substancially contribute to Europes renewable enegy mix.
Cadeler Secures Contract for BC-Wind Offshore Wind Farm Installation in Poland
Reported September 18, 2025 – Cadeler has signed a contract with Ocean Winds for the transportation and installation of 26 Siemens Gamesa 14 MW offshore wind turbines at the BC-Wind offshore wind farm in the Polish Baltic Sea. This agreement follows a Vessel Reservation Agreement (VRA) signed in February 2025 between the two companies.
Cadeler’s Role in the BC-Wind Offshore Wind Farm
Cadeler will also deploy one of its O-class wind turbine installation vessels for the project. Operations are scheduled to commence from the Port of Gdańsk, Poland, in 2028. They will last for approximately four months.
Project Importance
This project marks Ocean Winds’ first offshore wind initiative in Poland. It is also a significant step in the country’s renewable energy development as it continues to grow its portfolio with wind, solar and battery storage projects. This features the likes of 133 MW Trzebinia BESS project being developed by DRI and Fluence in southern Poland, and the 1 GW Baltic East offshore wind project.
The BC-Wind offshore wind farm also contributes to Poland’s ambitious offshore wind plans. It also continues to strengthen the nation’s position in the European offshore wind market.
Cadeler’s Involvement in Bałtyk II and III Offshore Wind Projects
In addition to the BC-Wind project, Cadeler also secured contracts for the installation of wind turbines at the Bałtyk II and Bałtyk III offshore wind farms in the Polish Baltic Sea. Equinor and Polenergia are developing these projects through a joint venture.
Additionally, Cadeler will utilize both its O-Class and P-Class installation vessels for the transportation and installation of the turbines. Operations are scheduled to commence in 2027, with the projects expected to be operational by 2028. The company also brings extensive experience to the project, having previously collaborated with Equinor on offshore wind initiatives.
The Bałtyk II and III projects are also among the largest offshore wind initiatives in Poland, aligning with the country’s commitment to increasing renewable energy capacity. These projects also contribute to the European Union’s broader energy transition objectives.
