Orlen and Northland Power finish installing 76 turbines at Poland's 1.2 GW Baltic Power offshore wind farm

Offshore installation completed

Crews have completed the assembly of the 76th and final wind turbine at the Baltic Power site in the Polish Baltic Sea. The project is developed jointly by Polish energy group Orlen, which holds a 51% stake, and Canada's Northland Power, with 49%. With all turbines standing, the offshore installation campaign has concluded 15 years after Orlen filed the initial concession application in 2011. Operating at a capacity of 1.2 gigawatts, the facility will generate up to 4 terawatt-hours of electricity annually, meeting about 3% of Poland's national electricity demand and supplying over 1.5 million households.

Orlen chief executive Ireneusz Fąfara addressed the milestone during a press conference on Wednesday.

76 turbines are installed. This is a great moment, because it also shows that we can build, for the first time in Poland, large investments in industry for which we had no prior experience, that we found great partners with whom we could do this, and that we are ready for next challenges.

Construction scale and offshore logistics

The Baltic Power farm spans 130 square kilometres, situated roughly 23 kilometres off the Polish coast near Łeba and Choczewo. The installation features 76 Vestas V236-15 MW turbines, each delivering an output of 15 megawatts. Individual blades measure 115 metres, sweeping a rotor area of 43,000 square metres, exceeding the area of six football pitches. Total height reaches over 250 metres above sea level, with foundations anchored up to 100 metres into the seabed.

The offshore campaign deployed approximately 7,000 workers and 110 vessels across an 18-month offshore construction schedule. Specialized jack-up vessels elevated themselves above the sea surface on seabed legs to hoist heavy components in Baltic weather conditions. In addition to the turbines, teams installed two offshore substations and laid hundreds of kilometres of subsea inter-array and export cables.

Testing and grid integration

Electricity generation began prior to final turbine placement. On 10 July 2026, the facility delivered initial power to the national grid via the Choczewo substation in Osieki Lęborskie, when 54 turbines were standing. Turbines are now undergoing grid synchronization and individual 240-hour reliability runs before operational handover.

Jarosław Broda, a board member at Baltic Power, described the operational transition.

The installation of the last turbine closes the offshore construction phase and opens the phase of commissioning, tests, and technical acceptances. We are checking whether each turbine operates correctly and meets the requirements of the transmission system operator.

Orlen stated that the entire facility will reach full commercial capacity by the end of 2026.

Domestic supply chain and local manufacturing

Polish suppliers account for approximately 21% of lifecycle spending on Baltic Power, delivering steel structures, cabling, foundation components, and logistics support. More than one-third of the nacelles were manufactured at the Vestas factory in Szczecin, while selected tower sections used recycled steel to decrease turbine carbon footprints. Orlen procurement director Roman Kowszewicz noted that the company established a dedicated team to apply supply chain lessons from Baltic Power to future offshore wind developments.

Northland Power chief executive Christine Healy assessed the completed installation.

Baltic Power is a breakthrough project for Poland and an excellent example of what can be achieved through strong partnerships. Together with Orlen, we are building a safer and more independent energy future for Poland, creating lasting value for future generations.
