The first phase of installing the rock-filling system to protect the seabed, further progress in the construction of the service base in Łeba, and developments at the onshore substations near Ustka, to which the first two transformers have been delivered, as well as the laying of most of the onshore connection – this is the state of play at the end of the first quarter of 2026 at the Bałtyk 2 and Bałtyk 3 farms, developed jointly by Equinor and Polenergia. The progress captured on video illustrates the parallel development of the project across multiple locations.
The first phase of the offshore installation campaign has begun, with specialised vessels deployed for the task. They are engaged in placing rocks (Subsea Rock Installation) on the seabed – an operation of crucial importance for the safety and durability of the infrastructure. In total, over one million tonnes of material will be delivered to the offshore construction site to protect the export and internal cables, as well as the turbine foundations, from the impact of waves and sea currents.
Manufacturing, assembly and preparations for the gradual transport of infrastructure components are underway at numerous facilities in Poland and abroad, including monopiles, transition pieces, subsea cables and selected components of offshore substations, including the main sections (topside). In addition, production of offshore wind turbine towers for the Bałtyk 2 project has commenced. The actual installation phase will soon begin in the Baltic Sea, starting with monopiles and transition pieces. The installation of export and internal cables will take place in the coming months.
Significant progress has also been made onshore. The offshore substations (ONS) for the Bałtyk 2 and Bałtyk 3 projects in Pęplin, in the municipality of Ustka, will be equipped with two transformers with a capacity of 450 MVA and weighing 352 tonnes each. Further finishing works and the installation of power equipment are ongoing. In parallel, the infrastructure for connection to the national power grid is being developed. The current progress of works for the 220 kV line is already close to 80%, and for the 400 kV line around 90%. Trenchless drilling using the HDD method is being carried out at the cable landfall section.
A key element of the onshore infrastructure is the operational and service base currently under construction in Łeba, which will serve as the management and service centre for offshore wind farms. The facility is currently in the final stages of construction and is being equipped with modern technical and storage infrastructure. A spare parts warehouse, office facilities with a remote wind farm control centre, and a quay for servicing vessels are being built there. At the same time, recruitment is underway for a team that will be responsible, among other things, for the operational functioning of the farms.
The Bałtyk 2 and Bałtyk 3 offshore wind farms, developed by Equinor and Polenergia, will have a combined capacity of 1,440 MW and will supply green energy to over 2 million households in Poland. The first electricity will flow into the grid in 2027, with commercial operation scheduled for 2028.
