Baltica 1

On 17 December 2025, the 896 MW Baltica 1 offshore wind project, developed by PGE’s subsidiary Elektrownia Wiatrowa Baltica 1, participated in Poland’s first competitive offshore wind support auction (AMFW/1/2025) run by the Energy Regulatory Office (URE). As part of this round, an additional bid was submitted specifically for Baltica 1 alongside bids for Bałtyk I, Baltica 9 and Baltic East. The auction offered long‑term negative‑balance coverage for successful projects and represented the first opportunity for Baltica 1 to secure revenue support under Poland’s post‑2025 offshore regime. Submission of the Baltica 1 bid marked the project’s formal entry into the competitive allocation process, following earlier environmental permitting and development work that had prepared it for auction readiness.

The Regional Director for Environmental Protection in Gdańsk issued an environmental decision for the Baltica 1 offshore wind farm, which enabled the 0.9 GW project to participate in Poland’s competitive offshore wind auction scheduled for 17 December 2025. Under the Offshore Wind Promotion Act regime, this auction is the route for securing a Contract for Difference (difference contract) that will underpin project revenues. The articles state that, with the decision in place, Baltica 1 can enter the auction planned for that specific date, implying that the bid window for the relevant round will close on 17 December 2025. At the time of the November 2025 reporting, this auction had not yet taken place and no outcome for Baltica 1 was known; the milestone is therefore a planned financial event rather than one that has already occurred.

On 17 October 2025, the Regional Director for Environmental Protection in Gdańsk issued the Decyzja o środowiskowych uwarunkowaniach (environmental decision, DŚU) for the Morska Farma Wiatrowa Baltica‑1 offshore wind project. The decision, currently non-final, covers the construction, operation and decommissioning of a wind farm of up to 900 MW, comprising 36–60 turbines rated 15–25 MW each, plus up to four offshore substations and around 140 km of internal array cables. The project area lies in Poland’s Exclusive Economic Zone east of Ławica Środkowa, about 75 km north of the coast near the Smołdzino and Łeba municipalities. Securing the DŚU is a key permitting milestone enabling Baltica 1 to proceed towards building permits and participation in offshore wind CfD auctions.

Ahead of issuing the environmental decision for Baltica 1 in October 2025, PGE Baltica completed comprehensive marine environmental studies for the project area. The work analysed seabed geological structure, physicochemical parameters of seawater and sediments, and the occurrence of marine organisms, including benthic plants and animals, fish, birds and marine mammals such as bats. The studies, carried out by a consortium including Gdynia Maritime University and MEWO, provided the environmental baseline needed to minimise impacts during construction and long‑term operation and directly supported the Regional Director for Environmental Protection in Gdańsk in issuing the environmental conditions decision for the Baltica 1 offshore wind farm on 17 October 2025.

By early January 2025, PGE Baltica had broadened its technical support for Baltica 1 and its wider offshore portfolio by selecting Ramboll as technical advisor across all of its offshore wind farm projects. Under this appointment, Ramboll will provide cross-project technical advisory services, supporting engineering and development activities for Baltica 1 alongside Baltica 2, Baltica 3, and new lease areas. Centralising technical advisory with a single international engineering consultancy is intended to ensure consistent design standards, efficiencies in project development, and coordinated technical oversight as PGE Baltica progresses multiple offshore wind investments in the Polish Baltic Sea.

By early 2025, PGE had completed a two‑year metocean data collection campaign using LiDAR technology for the 0.9 GW Baltica 1 offshore wind project. The LiDAR system gathered detailed information on wind conditions and other marine parameters at the project site, forming the basis for wind resource assessment, energy yield estimates, and design input for turbines and support structures. The completion of this long‑term measurement period significantly de‑risked the project by confirming the suitability of the site’s wind and metocean conditions for large‑scale offshore wind generation.

In 2024, PGE Baltica began geotechnical investigations for the onshore part of the 0.9 GW Baltica 1 offshore wind farm. The company reports that it "began investigating the subsoil" for onshore infrastructure and, in parallel, signed a contract for preliminary geotechnical studies of the seabed and geological studies for land–sea drilling, and selected a geotechnical and structural designer for subsoil exploration along the export cable route. These activities cover soil investigations on land and preparatory work for offshore and landfall geotechnical campaigns, providing data needed for the design of foundations, cable corridors, and associated civil works. The work advances Baltica 1 from high-level planning into detailed site characterisation ahead of future construction.

By the end of 2024, preliminary geotechnical campaigns for the Baltica 1 offshore wind farm had been carried out both offshore and along the future export cable route. Geoquip Marine executed a seabed geotechnical campaign to characterise the offshore soil structure where Baltica 1 will be built. At the same time, onshore and offshore investigations needed to plan horizontal directional drilling and other land‑sea works were performed by a Polish consortium led by Geofizyka Toruń. Completion of these campaigns provided key ground‑condition data for the connection infrastructure and overall project design.

In 2024, PGE Baltica advanced site investigations for the Baltica 1 offshore wind farm by commissioning a package of geotechnical and geological services. During the year, the company began subsoil investigations for the onshore part of the project, signed a contract for preliminary geotechnical studies of the offshore seabed and geological studies for land–sea drilling, and selected a geotechnical and structural designer for the subsoil exploration stage and along the planned export cable route. These contracted works will provide the data and engineering input required to define suitable foundation and cable solutions and to plan the technically feasible and environmentally compliant export corridor for evacuating power from Baltica 1 to shore.

In 2024, PGE Baltica advanced site investigations for the Baltica 1 offshore wind project by letting a set of geotechnical and geological contracts. The company reports that during the year it began investigating the subsoil for the onshore part of the project, signed a contract for preliminary geotechnical studies of the seabed and geological studies for land–sea drilling, and selected a geotechnical and structural designer for the subsoil exploration stage of the project and along the planned export cable route. These awards secure specialist contractors to characterise ground conditions both offshore and onshore, providing essential input for foundation concepts, drilling design and detailed routing of the export cable for the approximately 0.9 GW Baltica 1 wind farm located about 80 km off the Polish coast.

In 2024, PGE Baltica signed an agreement with ENERGOPROJEKT-KATOWICE S.A. to develop the conceptual design for the Baltica 1 offshore wind farm. The conceptual design focuses on selecting the optimal power derivation technology and includes extensive electrical analyses such as fixed and fault power flows, short-circuit studies, and preliminary harmonic assessments, alongside cost and reliability analyses. The documentation from this work will underpin subsequent detailed engineering for exporting power from the Baltica 1 site, an offshore area of around 0.9 GW capacity located roughly 80 kilometres off the Polish coast near Łeba. This contract represents a key early-development step, moving Baltica 1 from general planning into structured technical concept definition for its grid connection and electrical system.

On 5 August 2024, PGE Baltica signed an agreement with ENERGOPROJEKT‑KATOWICE S.A. to prepare a conceptual design for the Baltica 1 offshore wind farm. The scope includes electrical studies such as fixed and fault power flows, short‑circuit and preliminary harmonic analyses, together with cost and reliability assessments. The resulting documentation will underpin further design work on the optimal power‑derivation concept and grid connection solution for Baltica 1. This conceptual design contract marks a key early‑development engineering milestone for the project, translating resource and site data into a coherent technical concept.

On 5 August 2024, PGE Baltica, a PGE Group company responsible for offshore wind, announced that it had signed an agreement with Polish engineering firm ENERGOPROJEKT-KATOWICE S.A. to develop a conceptual design for the Baltica 1 Offshore Wind Farm. The conceptual design work focuses on selecting the most optimal technology for power evacuation from the approximately 0.9 GW project, including detailed electrical analyses such as fixed and fault power flows, short-circuit studies, and preliminary harmonic analyses, alongside cost and reliability assessments. The resulting documentation will underpin subsequent design stages for the power export system from Baltica 1, helping to mature the project towards later development and permitting milestones.

On 24 July 2023, Elektrownia Wiatrowa Baltica‑1, the PGE Group special purpose vehicle developing the Baltica 1 offshore wind farm, submitted an application initiating the environmental impact assessment procedure for the project to obtain a Decyzja o środowiskowych uwarunkowaniach (environmental decision). This filing with the Regional Director for Environmental Protection in Gdańsk formally opened the administrative proceedings for the approximately 900 MW Baltica 1 project, located about 75 km north of the Polish Baltic Sea coast in the country’s Exclusive Economic Zone. The application is a prerequisite for securing the environmental permit needed before building permits and participation in Poland’s offshore CfD auctions.

In autumn 2022, PGE Baltica’s contractors commenced a broad environmental research programme for the Baltica 1 offshore wind farm. The work covers marine environmental baseline studies in the Baltic Sea at the project site, providing data on natural conditions needed for permitting and design. These studies form part of the project’s early development and preceded both the detailed geotechnical campaigns and the subsequent environmental decision for Baltica 1.

In September 2022, PGE Group commenced environmental survey works for the approximately 900 MW Baltica 1 offshore wind farm in the Polish Baltic Sea. The surveys mark the start of detailed site investigations for the project, which is located about 80 kilometres from the Polish coast, north of the Baltica 2 and Baltica 3 areas. These environmental investigations form part of the early development phase needed to characterise site conditions, support permitting, and refine project design ahead of later-stage engineering and construction decisions. The surveys are an important step for Baltica 1, which already held a location permit (seabed siting consent) and a grid connection agreement by this point.

On 1 February 2021, PGE’s project company Elektrownia Wiatrowa Baltica-1 signed a transmission grid connection agreement with Polskie Sieci Elektroenergetyczne (PSE) for the Baltica 1 offshore wind farm, with an installed capacity of up to 896 MW. The agreement defines the terms for connecting the project, located more than 79 kilometres offshore near Łeba, to the national 400 kV transmission network via a new substation. This contract closes the formal preparations for power evacuation from PGE’s initial three offshore wind projects and significantly reduces technical and business risk for Baltica 1 by securing firm grid access for the planned post-2030 commissioning.

By early January 2021, Baltica 1 had secured a formal grid connection agreement with Polskie Sieci Elektroenergetyczne (PSE), Poland’s transmission system operator. Enerdata reports that, alongside a new connection agreement concluded for the 1,498 MW Baltica 2 project, the other two phases of the 3.4 GW Baltica complex, including the 896 MW Baltica 1 and 1,045 MW Baltica 3, had already obtained their connection agreements with PSE. This agreement confirms PSE’s commitment to provide a connection point and capacity for evacuating power from Baltica 1 into the national transmission system and is a prerequisite for later permitting, financing, and construction steps for the project, which is due to come online after 2030.

On 8 June 2020, PGE’s project company Baltica 1 Wind Power Plant received formal technical grid connection requirements from the Polish transmission system operator Polskie Sieci Elektroenergetyczne (PSE) for the planned 896 MW Baltica 1 offshore wind farm. The requirements define the connection capacity, necessary transmission infrastructure investments on both PGE and PSE sides, and the scope of arrangements with the President of the Energy Regulatory Office needed to enable evacuation of power from the wind farm. This milestone, issued for a site located about 80 kilometres offshore opposite Łeba in the Pomorskie province, represents an important step in securing grid access for Baltica 1 and advancing PGE’s wider offshore wind programme in the Polish Baltic Sea.

On 16 April 2012, the Polish Minister of Transport, Construction and Maritime Economy issued the key seabed location permit for the Baltica 1 offshore wind farm area. The decision defines an area of 108.19 km² in Poland’s Exclusive Economic Zone, east of the Central Bank shoal and around 75 km north of the coast near Smołdzino and Łeba. This permit, which authorises the construction and use of artificial islands, structures and devices for the Baltica 1 project, functions as the core seabed-rights instrument underpinning further development, including later environmental, geotechnical and design activities. The decision was subsequently amended in 2021, but the original permit date in 2012 marks the execution of seabed rights for Baltica 1.
