Baltica 2 is the largest offshore wind farm being built in the Polish part of the Baltic Sea. The 1.5 GW installation will supply energy to around 2.5 million households. Minister of Energy Miłosz Motyka attended the event inaugurating the start of offshore works.

“Offshore wind energy will become one of the foundations of Poland’s energy transition and of building our country’s energy security. The Baltica 2 offshore wind farm project is intended not only to generate electricity from renewable sources, but also to involve Polish companies in the development of a new sector of the economy. Moving into offshore works is a breakthrough moment for this project. We are getting closer to launching wind turbines that will provide clean energy to 2.5 million Polish households,” said Minister of Energy Miłosz Motyka.
A new stage of construction begins in the Baltic Sea
The new stage of the investment includes the installation of monopiles ‒ steel foundations on which the wind turbines and offshore substations will be mounted. A total of 111 monopiles will be installed: 107 for wind turbines and four for offshore substations. These are the largest structures used in Europe’s offshore energy sector. Each monopile is more than 100 meters long and weighs up to 2,000 tonnes.
The installation process includes transporting the monopiles from the port of Rønne, transferring them onto installation vessels, and precisely embedding the structures in the seabed. The project is being carried out in accordance with strict safety and environmental protection standards. During the works, measures such as bubble curtains to reduce underwater noise and monitoring for the presence of marine mammals are being used. These solutions help limit the project’s impact on the Baltic Sea ecosystem.
After this stage is completed, the next step will be the installation of export cables, which will connect the wind farm to the national power system through onshore grid connection infrastructure, as well as the installation of offshore substations.
In the subsequent phases of the project, the installation of inter-array cables and wind turbines will begin. At the same time, construction of the onshore substation and grid connection infrastructure is underway in the Choczewo municipality.
The wind farm will cover an area of about 190 sq km in the Baltic Sea between Ustka and Łeba, about 35–40 km from the shore.
Energy for millions of consumers and thousands of jobs
The project, being carried out by PGE and Ørsted, will be able to generate clean electricity corresponding to the demand of around 2.5 million consumers, including households, schools, hospitals, offices, and businesses.
The investment is important not only for the energy transition, but also for the development of the national economy.
Already today, Poland’s offshore sector:
- involves around 500 Polish companies
- generates thousands of jobs in industry, logistics, and services
- develops the technological expertise of domestic enterprises
- strengthens ports, shipyards, and production facilities across the country
The share of local content in the Baltica 2 project is 25–30%, with potential for further growth in the next stages of the sector’s development. Companies involved in the project include Grupa Przemysłowa Baltic, Crist Offshore, Polimex Mostostal, Tele-Fonika Kable, and domestic manufacturers of steel and infrastructure components.
The Baltic Sea is becoming a center for strategic energy investments
The development of offshore wind energy is also driving infrastructure investment in Polish ports and along the coast.
Key accompanying investments include:
- construction of the T5 installation terminal in Gdańsk, from which the turbines will be installed
- development of PGE Baltica’s operations and maintenance base in Ustka, from which the Baltica 2 offshore wind farm will be serviced
Installation of the turbines and commissioning of the Baltica 2 wind farm are planned for 2027. Once completed, it will be the largest offshore wind farm in Poland and one of the most important energy transition projects in the Baltic Sea region.
Offshore wind as a pillar of a modern energy system
Offshore wind energy is one of the key pillars of the transformation of Poland’s national energy system. Under the assumptions of the country’s energy policy, Poland plans to achieve:
- around 5.9 GW of offshore capacity by 2030
- as much as 11.8–17.9 GW by 2040
According to forecasts, the share of renewables in electricity generation will rise to around 50% by the end of this decade. Offshore wind is expected to play a strategic role in this process.
