Bałtyk I is an offshore wind farm being developed as a joint venture between Equinor and Polenergia. Planned to have a capacity of up to 1,560 MW, it is one of the largest offshore wind projects in Poland. The wind farm is progressing through the environmental approval and permitting stages, with construction and commercial operation timelines to be announced.
Additionally, the Equinor and Polenergi JV is also developing the Bałtyk II and Bałtyk III offshore wind farms as large-scale renewable energy projects. They are also located in the Polish Baltic Sea. Combined, they have a total capacity of 1,440 MW. Construction activities began following the projects’ environmental approvals and financial close in May 2025.
Cadeler, a global offshore wind contractor, is scheduled to start turbine transportation and installation at the Bałtyk II and III farms in 2027. The operations will utilize both O-Class and P-Class installation vessels, with full commercial operation expected by 2028. The company also recently won a contract for the transportation and installation of 26 Siemens Gamesa 14 MW offshore wind turbines at the BC-Wind offshore wind farm. The wind farm is also located in the Polish Baltic Sea.

Equinor and Polenergia Secure Key Environmental Approval for Bałtyk 1 Offshore Wind Farm
Reported April 29, 2025 – Equinor and Polenergia secured the final environmental decision for the Bałtyk 1 Offshore wind farm project from the Regional Director for Environmental Protection (RDOŚ) in Gdańsk. This approval marks a significant step toward what is expected to become one of the largest offshore wind farms in the Polish Baltic Sea. It also makes it eligible to participate in Poland’s 2025 offshore wind auction scheduled for December 17, 2025.
In preparation, Equinor and Polenergia have also submitted a prequalification application for Bałtyk I, marking it as the first project to apply for this auction. Additionally, with a capacity of up to 1,560 MW, Bałtyk I is positioned as the largest and one of the most advanced offshore wind projects in Poland.
With a planned capacity of up to 1,560 MW, Bałtyk 1 will be located approximately 80 kilometers offshore. Electricity generated by the project will be transmitted to the Krzemienica substation. Infrastructure through Ustka and Redzikowo municipalities will be used.
On Track for 2025 Offshore Wind Auction
The developers also highlighted the importance of holding the second-phase auction in 2025 to sustain offshore development momentum.
Adam Purwin, CEO of Polenergia, emphasized the need for continuity to avoid delays and maximize the energy potential of Poland’s coast. Michał Jerzy Kołodziejczyk, Equinor’s Country Manager in Poland, also noted that Bałtyk 1 offshore wind farm is the most advanced project in this phase of development.
Commitment to Local Industry and Supply Chain
Equinor and Polenergia are actively engaging Polish businesses in the offshore wind supply chain. Supplier meetings have also attracted participation from over 300 local companies with several domestic firms already being contracted as tier-1 suppliers. Contractor meetings for Bałtyk 1 will also be held soon.
A Clean Energy Future for Poland
Together, the three Bałtyk projects will deliver up to 3,000 MW of clean energy. This is enough to power 4 million homes. Bałtyk 1 expects first power by 2030, while Bałtyk 2 and 3 expect it by 2028.
