Ørsted and PGE Polska Grupa Energetyczna have officially launched full-scale offshore construction on the Baltica 2 offshore wind farm, marking a major milestone for Poland’s energy transition.

The first monopile foundations have now been successfully installed in the Polish sector of the Baltic Sea, with installation works being carried out by offshore contractor Van Oord.

1.5GW project to power 2.5 million homes

Baltica 2 will become Poland’s largest offshore wind farm, with a total installed capacity of 1.5GW. Once operational, the project is expected to generate between 5 and 6TWh of electricity annually, enough to supply around 2.5 million Polish households.

The wind farm is located approximately 40 kilometres off the Polish coast near Ustka and is being developed, owned and operated under a 50/50 partnership between Ørsted and PGE.

Full commissioning is expected in 2027, with offshore installation works scheduled to continue through Q4 2026.

Large-scale offshore installation campaign

The construction campaign includes the installation of 111 monopiles in total:


107 foundations for wind turbines
4 foundations for offshore substations

Each monopile is approximately 100 metres long, weighs around 1,500 tonnes, and has a diameter exceeding 10 metres. The structures are engineered to withstand harsh marine conditions for up to 30 years and are individually designed according to site-specific requirements.

Installation is being carried out using specialised offshore vessels, including Aeolus and Svanen operated by Van Oord, supported by Cadeler and Fred. Olsen Windcarrier for turbine installation activities.

Strategic project for Poland and Europe

Rasmus Errboe, CEO of Ørsted, said the start of offshore construction marks an important step for energy security in both Poland and Europe.

He highlighted that offshore wind will play a key role in building a more resilient and sustainable energy system, while also creating long-term industrial and employment opportunities in Poland.

PGE Polska Grupa Energetyczna CEO Dariusz Lubera described the start of construction as a breakthrough moment for the Polish energy sector, noting that Baltica 2 is the country’s largest renewable energy project by capacity.

He added that the project will strengthen energy security, provide a stable source of zero-emission electricity, and reduce dependence on fossil fuel imports.

Long-term contract and financial framework

Baltica 2 operates under a 25-year inflation-protected Contract for Difference (CfD) with the Polish state. The agreement guarantees a fixed revenue structure indexed to inflation, with pricing based on a 2021 reference level of €71.82/MWh plus inflation adjustments until commissioning.

After the CfD period ends, the project will either sell electricity at market prices or through future power purchase agreements.

Strong supply chain involvement

Van Oord CEO Govert, said the company is proud to contribute to Poland’s energy transition through its offshore installation work, highlighting the complexity and weather-sensitive nature of marine construction.

He stressed that the project reflects close collaboration across the supply chain and builds on previous offshore wind experience in partnership with Ørsted.

A key milestone for Baltic offshore wind

Baltica 2 is expected to become one of the most significant offshore wind developments in the Baltic Sea region, reinforcing Poland’s role in Europe’s accelerating renewable energy expansion.

With permits secured, grid connection agreements in place, and offshore construction now underway, the project represents a major step forward in delivering large-scale clean energy infrastructure in Central and Eastern Europe.
