Wind Energy – Baltyk
Offshore construction has officially begun on the Bałtyk 2 and Bałtyk 3 offshore wind projects in Poland, jointly developed by Equinor and Polenergia.
Together, the two projects will feature 100 wind turbines with a combined installed capacity of 1.4 GW, marking a significant milestone in Poland’s energy transition and the development of offshore wind in the Baltic Sea.
The 2026 offshore construction campaign represents a major phase of the projects and will include the installation of 100 monopile foundations, transition pieces (TPs), offshore substation components, subsea export and inter-array cables, and supporting offshore infrastructure.
More than 20 vessels will be engaged in the construction activities during 2026 alone, highlighting the scale and complexity of the operation.
The first phase of offshore works commenced in January with subsea rock installation, carried out by Van Oord. Four specialized vessels were deployed to complete this initial scope of work, preparing the seabed for foundation installation.
Beginning in spring, transport and installation activities will ramp up with the installation of monopiles, transition pieces, and selected components of the two offshore substations. Heerema Marine Contractors’ heavy-lift installation vessel Thialf will be deployed for these critical operations.
In the months that follow, installation of export cables and inter-array cables will continue, further advancing the construction of the wind farms.
Equinor’s operations and maintenance (O&M) base in Łeba will be completed and commissioned later this year. The facility will serve as the central coordination hub for vessel traffic and offshore construction activities, and subsequently support long-term operations of the wind farms.
Once operational, Bałtyk 2 and Bałtyk 3 will play a key role in strengthening Poland’s renewable energy capacity and enhancing energy security in the region.
