Baltica 2

By mid-February 2026, the initial campaign of geotechnical surveys along Baltica 2’s cable corridors had been completed as part of the first stage of seabed preparation, enabling subsequent boulder removal, trenching, and readiness for inter-array and export cable installation.

Developers Ørsted and PGE plan to begin offshore installation of the Baltica 2 export cables in 2026. Project communications indicate that manufacturing of the 275 kV export cables has started, with offshore installation scheduled to commence in 2026, and a February 2026 update confirms that installation of export cables and offshore substations will begin later that year. Under previously signed agreements, Boskalis will carry out the laying and burial of about 300 km of offshore export cables as part of this campaign, following the dedicated seabed preparation and corridor‑trenching works.

In 2025, Boskalis commenced cable trenching for Baltica 2’s subsea cable corridors using the multi‑mode Megalodon plough deployed from the vessel BOKA Falcon, following earlier geotechnical investigations, UXO clearance, and corridor boulder removal along both inter-array and export cable routes. This first stage of seabed preparation created trenched corridors over 150 km of inter-array routes and initiated preparation for the future 260 km export cable route needed for the Baltica 2 Export system.

Geotechnical surveys along the planned inter-array and export cable routes for Baltica 2 began as the first step in the seabed preparation campaign, providing ground condition data needed before boulder clearance, trenching, and cable installation works proceeded.

Following the initial geotechnical work for Baltica 2, contractors commenced checks for unexploded ordnance (UXO) along the planned cable corridors, a prerequisite for continuing seabed preparation and installation activities safely.

Project updates confirm that manufacturing of the Baltica 2 offshore export cables has started in advance of the planned offshore installation campaign beginning in 2026. This marks a key supply-chain milestone for the 275 kV export cable system that will connect the offshore substations to the onshore substation at Osieki Lęborskie.

By 22 December 2025, construction of the Baltica 2 export grid’s onshore substation at Osieki Lęborskie in the Choczewo commune was well advanced. A consortium of GE Vernova and Polimex Mostostal was executing works on the nearly 13‑hectare site, with main civil works completed, installation of 275 kV and 400 kV gas‑insulated switchgear buildings under way, and busbar and gantry structures linking the node to transmission operator PSE’s network already erected. In parallel, horizontal directional drilling works near the coastline were progressing to connect the offshore 275 kV export cables with the approximately six‑kilometre onshore cable route to the substation, marking substantive progress on the onshore elements of the Baltica 2 export connection.

Construction of the Baltica 2 onshore substation at Osieki Lęborskie in the Choczewo commune, which receives power from the 275 kV export cables and steps it up to 400 kV for injection into Poland’s national grid, is being executed by a consortium of GE Vernova and Polimex Mostostal under a dedicated construction contract. The consortium is delivering the nearly 13-hectare facility, including civil works and installation of high-voltage equipment, as part of the overall grid-connection infrastructure for Baltica 2.

Toward the end of 2025, offshore site preparation for Baltica 2’s cable corridors, including the export cable route, advanced significantly. Following earlier geotechnical investigations and checks for unexploded ordnance along the planned cable routes, contractors removed large boulders up to two metres in size from both inter-array and export cable corridors using the T‑Rex plough deployed from Boskalis’s vessel BOKA Falcon. At the end of 2025, cable trenching began with the Megalodon plough, preparing the seabed so that, after installation, the cables can be correctly laid and protected; this first trenching campaign covered 150 km of cable routes and formed a key part of the offshore preparation for the Baltica 2 export connection.

In August 2025, Boskalis began offshore site preparation for the Baltica 2 offshore wind farm, starting boulder clearance and corridor preparation along the planned inter-array and export cable routes. Using the vessel BOKA Falcon with the T‑Rex plough, the contractor cleared the seabed following geotechnical and UXO surveys, initiating the seabed preparation campaign ahead of cable trenching and installation.

PGE confirmed it had obtained loans for its 50% share of Baltica 2 financing, including about PLN 6 billion in loans from Bank Gospodarstwa Krajowego (BGK), of which approximately PLN 5.5 billion comes from Poland’s National Recovery Plan. These BGK and NRP‑backed facilities form part of the project finance structure for Baltica 2, while Ørsted finances its share from its own capital.

PGE and Ørsted reported that construction of the onshore connection infrastructure for the Baltica 2 offshore wind farm had already started by early February 2025. This work covers the onshore transformer substation and underground cable lines in Osieki Lęborskie, Choczewo municipality, which will route electricity from the offshore wind farm into the Polish power system.

According to Ørsted's 29 January 2025 press release "Ørsted and PGE take final investment decision on Baltica 2 Offshore Wind Farm", Ørsted and PGE "have taken final investment decision (FID) on the 1.5 GW Baltica 2 Offshore Wind Farm" on that date.
