Baltic East is the most advanced offshore wind project being developed by ORLEN Neptun.The planned wind farm, covering an area of approximately 110 km², is being developed within site 46.E.1. With an installed capacity of 900 MW, the project has the potential to supply clean energy to over one million households in Poland.
The project is being developed pursuant to a decision issued by the Ministry of Infrastructure in October 2023, granting the ORLEN Group five new sites for the construction of offshore farms in the Baltic Sea with an estimated total installed capacity of about 5.2 GW.
The project carried out within site 46.E.1 has obtained preliminary grid connection conditions, a permit to erect or use artificial islands, structures and equipment, a permit to lay and maintain cables, as well as an environmental decision for the offshore wind farm, issued by the Regional Directorate for Environmental Protection in Gdańsk. In December 2025, the Baltic East project was among the winners of the first Polish offshore wind auction conducted by the President of the Polish Energy Regulatory Office.
Winning the auction marks the transition of the Baltic East project into an advanced development phase, which will culminate in the Final Investment Decision (FID). Further activities will include continued design and technical analyses, site investigations, and the acquisition of the required decisions and permits. The commercial operations date (known as COD), i.e. when the offshore wind farm will start generating electricity, is estimated for 2032.
Location
The Baltic East farm will be located about 22.5 kilometers off the Polish coast near Choczewo. This is the area directly adjacent to the Baltic Power offshore wind farm currently under construction (approx. 1.2 GW), a joint investment by ORLEN and Northland Power, which is schedueled to become operational in 2026.
The planned area of the Baltic East project is approximately 110 km², with water depths ranging from around 25 to 40 meters below sea level.
Estimated technical parameters of the wind farm
According to the current assumptions of the Baltic East project, the wind farm is planned to comprise several dozen offshore wind turbines, each with unit capacity aligned with the latest technologies offered by leading manufacturers. The turbines will be placed on monopile, or jacket, or other types of foundations, depending on the results of geological surveys and available technologies.

Project timeline
According to the current project timeline, the Baltic East project is developed in a schedule enabling it to participate at the National Offshore Auction, scheduled for 2025. ORLEN Neptun offshore wind excellence centre is proceeding the initial phase works, including preparations to a wide range of environmental surveys, project design and consenting.
