Baltic Power has confirmed that the first monopiles have been installed in the offshore wind farm of the same name, following the project schedule. This marks the official start of offshore construction for Poland’s first wind farm in the Baltic Sea.

The installation vessel Svanen has installed the first monopiles in the Baltic Power offshore wind farm area, according to Baltic Power, a company jointly owned by ORLEN Group and Northland Power. The company has stated that the operation is proceeding as planned.

According to reports, the monopile installation began at the end of January. The main installation work is being carried out by the Svanen vessel, whose task is to lift monopiles to a vertical position after being towed by tugboats, position them precisely on the seabed, and drive them approximately 40 meters into the ground.

A total of 78 monopiles will be installed. These are steel tubes up to 100 meters long, weighing up to 1,700 tons, and with a diameter exceeding 9 meters—larger than a metro tunnel. The monopiles will support the previously contracted 15 MW turbines.

"Our new strategy is about concrete actions, and this is evident in the case of Poland’s first offshore wind farm. After several months of intense work, we are pleased to announce that the first foundations for the Baltic Power farm have been installed. The year 2025 will be a breakthrough for this project. Hundreds of our workers will carry out the largest offshore installation works in history, so that by 2026, energy from the Baltic Sea will start flowing to consumers for the first time. This is a clean, stable, and secure energy source that will drive Poland’s economy. Polish companies will grow alongside our project. This is the energy of tomorrow, which begins today," said Ireneusz Fąfara, CEO of ORLEN.

Alongside the installation crane, more than a dozen other vessels are operating on-site, including support vessels, tugboats, personnel and equipment transport ships, environmental monitoring units, and security vessels. The Baltic Power Marine Coordination Center monitors all construction activities and maritime traffic around the site 24/7. Weather conditions play a crucial role in determining the pace of operations.

Next, transition pieces connecting the foundations with the turbines will be installed, followed by offshore wind turbines, offshore substations, and cables linking them together and exporting energy to the mainland. Installation work will continue until 2026.

"The installation of the first foundations for the Baltic Power wind farm is a significant milestone in the development of offshore wind energy in Poland. We are proud of our partnership with ORLEN Group on this pioneering project. As partners in the construction of Poland’s first offshore wind farm, we are excited to bring our global expertise to this endeavor. This milestone not only demonstrates our shared progress but also strengthens our determination. Safety remains our top priority at every stage, ensuring the highest standards across all aspects of the project. Today’s achievement is a testament to the strong partnership between Northland and ORLEN Group and further reinforces our commitment to Poland’s energy future," said Christine Healy, President & CEO of Northland Power Inc.

Meanwhile, the construction of onshore infrastructure is also progressing. In Osieki Lęborskie, within the Choczewo municipality, a land-based power station is being built to transfer the generated energy to the national grid operator. The construction is approximately 65% complete, with completion expected between late 2025 and early 2026.

Additionally, in nearby Lubiatowo, two out of four directional drillings have been completed for underground cable connections, designed to protect ecologically valuable dune and beach areas. In Łeba, construction of the Baltic Power service base, which will support the wind farm throughout its approximately 30-year operational period, is nearing completion.
