The Baltica 2 wind farm, situated in the Baltic Sea, marks Ayesa’s debut in offshore projects in Poland. Scheduled to be operational from 2027, it will feature 107 wind turbines with a total capacity of 1.5 GW, providing renewable electricity to approximately 2.5 million people.
Ayesa Ingeniería has been chosen to oversee the construction of Baltica 2, which stands as one of Europe’s largest renewable energy initiatives and is a key step in Ayesa’s involvement with offshore wind in Poland. This project is expected to set new benchmarks in both technical efficiency and environmental sustainability, strengthening Ayesa’s role as a major partner in the clean energy sector.
Poland is currently advancing its energy transition, with strong government backing for offshore wind. The wind farm will span about 190 km² between Ustka and Choczew, roughly 40 kilometers from shore. The project is being developed by the Polish state utility PGE and Danish offshore wind leader Ørsted, with an investment projected to exceed €1 billion and completion targeted for November 2027.
Ayesa Polska will supervise all offshore aspects, including the installation of turbines, foundations, export cables, and marine transformer stations. While Ayesa has extensive experience with onshore wind and solar projects in Poland, Baltica 2 is its first offshore assignment in the country.
The wind farm will use Siemens Gamesa SG 14-222 DD turbines, each with a 14 MW output and a 222-meter rotor, ensuring high energy efficiency. In addition to the turbines, the project involves building both onshore and offshore transformer stations, installing around 180 km of high-voltage cables (275 kV), and developing the grid connection to the Choczewo substation. An operations and maintenance base will also be established at the port of Ustka.
To protect marine life, advanced installation methods and noise reduction measures will be implemented. According to Artur Majczak, Ayesa Polska’s country manager, Baltica 2 is expected to create about 2,500 jobs during construction and operation, improve local infrastructure, and support regional development. The wind farm is also set to play a significant role in helping Poland reach its offshore wind target of 5.9 GW by 2030.
Through this project, Ayesa is reinforcing its position as a key contributor to Europe’s energy transition, expanding its expertise in complex marine engineering, and affirming its commitment to sustainable development on a global scale.
