Ayesa Engineering will supervise the construction of Baltica 2, one of the largest renewable projects in Europe

This wind farm in the Baltic Sea is the largest in Poland and Ayesa’s first offshore project in this country.

With 107 wind turbines and 1.5 Gw of power, it will supply clean energy to 2.5 million citizens as of 2027.

Ayesa Engineering, a global provider of technology and engineering services, will supervise the construction of the Baltica 2 offshore wind farm in Poland, one of the largest renewable energy projects in Europe and the first offshore project in which the company is involved in this country. This large-scale project will be a milestone in technical efficiency and environmental sustainability, consolidating Ayesa’s position as a strategic partner in the clean energy sector.

Poland is living a key moment in its energy transition with the firm commitment of its Government to offshore wind energy. Baltica 2 envisages the installation in the Baltic Sea of 107 wind turbines totaling 1.5 Gw of power. It will cover an area of approximately 190 km² belonging to Poland, between the towns of Ustka and Choczew, and some 40 kilometers from the coast. The promoters of this mega-project are the Polish state-owned electricity company PGE and the Danish company Ørsted, a world leader in offshore wind energy. The planned investment exceeds one billion euros and construction is scheduled for completion in November 2027.

PGE has awarded Ayesa Polska the supervision of the entire offshore part of the wind farm, including the installation process of turbines, foundations, export cables and offshore transformer stations. The company has extensive experience in Poland in onshore wind farms and photovoltaic installations, but Baltica 2 will be its first challenge in the field of offshore renewables in this country.

 

 

The 107 Siemens Gamesa SG 14-222 DD turbines that will be used are among the most advanced on the market, each with a capacity of 14 MW and a rotor diameter of 222 meters, ensuring high efficiency in energy production. This facility will generate clean electricity from Baltic wind power to meet the demand of some 2.5 million citizens. In addition to these windmills, the project includes the construction of onshore and offshore transformer stations, the laying of some 180 km of high-voltage (275 kV) power cables, and the development of a transmission infrastructure that will connect to the Choczewo power substation. An operations and maintenance base will also be built at the port of Ustka.

Advanced installation techniques and noise reduction measures will be applied to minimize the impact on marine life.

Artur Majczak, country manager of Ayesa Polska emphasizes that “Baltica 2 will have a significant socio-economic impact on the region, with the generation of an estimated 2,500 jobs during the construction and operation phases, as well as the improvement of onshore infrastructure and the promotion of local development”. This facility is expected to contribute significantly to Poland’s goal of reaching 5.9 GW of offshore wind energy by 2030.

With this project, Ayesa reinforces its role as a key player in Europe’s energy transformation, expanding its expertise in complex engineering in offshore environments and its commitment to sustainable development on an international scale.
