Ayesa Ingeniería will supervise the construction of one of Europe’s largest renewable energy projects
The Baltica 2 wind farm, named after its location in the Baltic Sea, is Ayesa’s first offshore project in Poland.
With 107 wind turbines and 1.5 GW of power, it will supply clean energy to 2.5 million citizens from 2027 onwards.
Ayesa Ingeniería 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 at a key moment in its energy transition with its government’s firm commitment to offshore wind energy. Baltica 2 involves the installation of 107 wind turbines in the Baltic Sea with a total capacity of 1.5 GW. It will cover an area of approximately 190 km² between the cities of Ustka and Choczew, about 40 kilometres from the coast. The developers of this megaproject are the Polish state-owned electricity company PGE and the Danish company Ørsted, a world leader in offshore wind energy. The investment may exceed €1 billion and the work is expected to be completed in November 2027.
PGE has awarded Ayesa Polska the contract to supervise the entire offshore part of the wind farm, including the installation of turbines, foundations, export cables and marine 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 renewable energy in this country.
The 107 Siemens Gamesa SG 14-222 DD turbines to be used are among the most advanced on the market, each with a capacity of 14 MW and a rotor diameter of 222 metres, ensuring high efficiency in energy production. This facility will generate clean electricity from Baltic wind energy to meet the demand of around 2.5 million citizens.
In addition to these turbines, the project includes the construction of onshore and offshore transformer stations, the laying of approximately 180 km of high-voltage electrical cables (275 kV), and the development of a transmission infrastructure that will connect to the Choczewo electrical substation. An operations and maintenance base will also be built in the port of Ustka.
Advanced installation techniques and noise reduction measures will be applied to minimise the impact on marine life.
Artur Majczak, country manager of Ayesa Polska, emphasises that Baltica 2 ‘will have a significant socio-economic impact on the region, with an estimated 2,500 jobs created during the construction and operation phases, as well as improvements to land 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 marine environments and its commitment to sustainable development on an international scale.
