Baltica 9 (marketed post-acquisition as Baltica 9+) is a consolidated offshore wind cluster on the western Słupsk Bank in the Polish Baltic Sea combining PGE’s 975 MW Baltica 9 concession (area 44.E.1) with the adjacent FEW Baltic II project (originally ~350 MW under RWE). Together the assets for...
Owners
On 10 March 2026 RWE and PGE closed the transaction announced in December 2025, with PGE Polska Grupa Energetyczna S.A. becoming the sole owner of the F.E.W. Baltic II offshore wind development project (approx. 350 MW) in the Polish Baltic Sea. The transferred entity is the RWE Offshore Wind Poland sp. z o.o. project company. With FEW Baltic II under PGE ownership the asset is now developed jointly with the adjacent Baltica 9 (44.E.1) area as the Baltica 9+ cluster — approximately 1.3 GW combined capacity, targeting commercial operations by 2032.
By mid-December 2025, PGE confirms that the 975 MW Baltica 9 offshore wind farm has obtained preliminary grid connection conditions, a key regulatory milestone for connecting the project to the Polish transmission system. The project is located in basin 44.E.1 on the western Słupsk Bank, around 48 kilometres from the coast, and is part of the wider Baltica 9+ cluster that will total about 1.3 GW when combined with the neighbouring FEW Baltic II project. Securing preliminary connection conditions indicates that the transmission operator has defined the basic technical and capacity parameters for Baltica 9’s future grid connection, reducing regulatory uncertainty and enabling further design, permitting and commercial work ahead of construction and the planned 2032 commissioning. This grid step sits alongside other preparatory activities such as completion of 2D UHRS geophysical surveys and a preliminary geotechnical campaign.

On 18 December 2025, in parallel with securing a Contract for Difference for the 975 MW Baltica 9 project in Poland’s first offshore wind auction, PGE signed a conditional agreement with RWE to acquire RWE Offshore Wind Poland sp. z o.o., the company holding the adjacent FEW Baltic II offshore wind project of approximately 350 MW. Bringing FEW Baltic II under PGE’s control next to Baltica 9 will create an integrated offshore wind development with a total capacity of about 1.3 GW, referred to as Baltica 9+, enabling PGE to pursue economies of scale in developing and operating this cluster on the Słupsk Bank.
On 17 December 2025, PGE’s subsidiary Elektrownia Wiatrowa Baltica 9 sp. z o.o., which is developing the 975 MW Baltica 9 offshore wind farm in area 44.E.1, secured a two-sided Contract for Difference (CfD) in Poland’s first competitive offshore wind auction (AMFW/1/2025). The President of the Energy Regulatory Office (URE) granted Baltica 9 the right to cover the negative balance of electricity generated and fed into the grid for a 25‑year period. The CfD sets a net strike price of PLN 489.00/MWh and underpins project revenues, providing long-term price stability that supports financing and progression towards construction. The expected commercial operations date for Baltica 9 under this support contract is 17 December 2032. This award also formed the basis for PGE’s broader Baltica 9+ concept, combining Baltica 9 with the neighbouring FEW Baltic II project into a roughly 1.3 GW cluster.
As of mid-December 2025 PGE Baltica reported that an initial geotechnical survey campaign for the Baltica 9 site (area 44.E.1) was underway and in its final stage, complementing the completed 2D UHRS geophysical surveys by Geofizyka Toruń. No exact start date is disclosed in the source pack; month-precision December 2025 is used here as the latest period in which the source explicitly confirms the survey is in progress. The geotechnical data supports foundation and cable design decisions for the subsequent procurement phase scheduled to commence in 2026.
For Baltica 9, the 2D ultra‑high‑resolution geophysical campaign by Geofizyka Toruń S.A. was planned to run offshore from early May to mid‑June 2025, followed by several months of data processing and interpretation. The analytical work and delivery of results were scheduled to be completed by November 2025. Subsequent project updates state that 2D UHRS geophysical surveys for Baltica 9 have been conducted, indicating that the planned survey and its associated analysis were completed by late 2025, providing detailed seabed understanding ahead of further geotechnical investigations and project optimisation.
On 25 November 2025, Elektrownia Wiatrowa Baltica 9 sp. z o.o. concluded an asset purchase agreement with Carmagnola sp. z o.o. and RWE Offshore Wind Poland sp. z o.o. Under this agreement, the sellers transferred key environmental rights and documentation for the Baltica 9 project’s generation area (44.E.1) to the Baltica 9 SPV. The package included Environmental Decision no. 12/2025 for the generation part of area 44.E.1, the associated Environmental Impact Assessment Report, and underlying environmental data. Securing these assets enabled Baltica 9 to participate in Poland’s December 2025 offshore wind auction for Contract for Difference support, effectively accelerating the project’s permitting status by several years by building on prior work undertaken for the site.
As part of preparations for Baltica 9, PGE Baltica awarded a contract to a consortium of Geo Ingenieurservice Polska and Baltic Diving Solutions to survey the Baltic Sea seabed for unexploded ordnance and shallow gas. The scope includes specialist geophysical work, data processing, and issuing ALARP certificates for locations where geotechnical surveys will later be performed. This UXO‑focused survey campaign is scheduled for the third quarter of 2025 and will be conducted along routes pre‑defined by the preceding 2D UHRS geophysical campaign, helping to ensure that subsequent intrusive investigations can proceed safely.
On 16 May 2025, PGE Baltica signed a contract with a consortium of Geo Ingenieurservice Polska and Baltic Diving Solutions to perform a specialist geophysical survey of the Baltic Sea seabed for the Baltica 9 offshore wind farm. The scope covers geophysical measurements, data processing and analysis, and issuing ALARP certificates for selected sites where future geotechnical investigations are planned. The survey is planned for the third quarter of 2025 and will be carried out in locations defined by the earlier 2D UHRS campaign by Geofizyka Toruń S.A., further refining seabed knowledge for detailed design and safe geotechnical works.
An environmental impact assessment for the generation part of the Baltica 9 offshore wind farm (area 44.E.1) was approved through Environmental Decision no. 12/2025, issued on 27 June 2025. The decision, together with its associated Environmental Impact Assessment Report and environmental data, covers the offshore generation infrastructure within the 44.E.1 concession area. Later, on 25 November 2025, PGE’s project company Elektrownia Wiatrowa Baltica 9 sp. z o.o. entered into an assets purchase agreement with Carmagnola sp. z o.o. and RWE Offshore Wind Poland sp. z o.o. to acquire this Environmental Decision and related environmental documentation. Securing this DŚU-type environmental consent was a key prerequisite enabling the Baltica 9 project to participate in Poland’s first competitive offshore wind auction (AMFW/1/2025).
PGE Baltica contracted Geofizyka Toruń S.A. to carry out a 2D ultra‑high‑resolution geophysical survey, including high‑resolution reflection seismic and simultaneous bathymetric measurements, for the Baltica 9 offshore wind farm area. According to the April 2025 announcement, offshore measurements were scheduled to start in the first half of May 2025 and continue until mid‑June. The campaign aims to characterise seabed geology down to 100 metres and identify risks such as shallow gas pockets, palaeochannels and glacial till, providing key input for project design and auction preparation. Later company communications confirm that these 2D UHRS geophysical surveys have been conducted.
On 16 May 2025, PGE Baltica awarded a further survey contract for the Baltica 9 offshore wind farm, signing with a consortium of Polish companies Geo Ingenieurservice Polska and Baltic Diving Solutions. The consortium will conduct a specialist geophysical survey of the Baltic Sea seabed focused on detecting unexploded ordnance and shallow gas in locations pre‑selected from a preceding 2D ultra‑high‑resolution seismic campaign performed by Geofizyka Toruń. Their scope includes executing the surveys, processing and analysing the acquired data, and issuing ALARP (as low as reasonably practicable) certificates for sites where future geotechnical investigations are planned. The work is scheduled for the third quarter of 2025 and will support safe planning of detailed geotechnical campaigns and foundation design. This award strengthens the Polish supply chain’s role in Baltica 9’s development by engaging domestic marine survey and diving specialists.
On 28 April 2025, PGE Baltica signed a contract with Polish geophysical specialist Geofizyka Toruń S.A. to deliver site investigation services for the Baltica 9 offshore wind farm. Under the agreement, Geofizyka Toruń will carry out geophysical surveys using high‑resolution reflection seismic combined with bathymetric measurements over the Baltica 9 licence area on the western Słupsk Bank, about 48 kilometres from shore and covering roughly 121 square kilometres. Offshore measurements are scheduled to run from the first half of May until mid‑June 2025, with analytical work and delivery of results planned by November 2025. The campaign will characterise subsurface geology down to 100 metres and identify hazards such as shallow gas, paleochannels and glacial tills. This procurement marks a key early contract award supporting Baltica 9’s preparation for participation in Poland’s offshore auction and subsequent wind farm construction.
On 3 December 2024 the Voivode of West Pomerania (the regional building-permit authority for offshore wind projects under Polish law) issued two key decisions granting construction permits for the 350 MW F.E.W. Baltic II offshore wind farm, then owned by RWE Offshore Wind Poland sp. z o.o. The permits cover the offshore wind turbines, the inter-array and telecommunications cables and the offshore substation, completing the principal building-permit package for the FEW Baltic II portion of what subsequently became the Baltica 9+ cluster. RWE indicated at the time that the remaining building permits were expected to follow in Q1 2025. This planning consent was inherited by PGE through the closing of the FEW Baltic II SPV acquisition on 10 March 2026 and supports the consented status of the wider Baltica 9+ project alongside the December 2025 Baltica 9 CfD award.
In 2023, PGE secured seabed rights for several new offshore wind locations in the Polish Baltic Sea. Baltica 9, a 975 MW project in basin 44.E.1 on the western part of the Słupsk Bank, is explicitly described as being situated in one of five locations awarded to PGE that year. This award effectively designates area 44.E.1 for development by PGE and underpins the subsequent planning of the Baltica 9 offshore wind farm, including its integration into PGE’s broader Baltic portfolio and later clustering with the adjacent FEW Baltic II project into the Baltica 9+ undertaking.
In April 2021, the neighbouring FEW Baltic II offshore wind project, originally held by RWE Offshore Wind Poland sp. z o.o., secured a two‑sided Contract for Difference (CfD) under Poland’s first‑phase administrative offshore wind support regime. The project, with a capacity of approximately 350 MW, obtained Phase I CfD support via a ministerial by-law, completing the two‑step allocation process under the Offshore Wind Promotion Act. This CfD gives FEW Baltic II long‑term revenue stability and a defined strike price (not disclosed in the cited texts). When PGE later agreed to acquire RWE Offshore Wind Poland and integrate FEW Baltic II with the adjacent Baltica 9 site, this existing Phase I CfD became part of the Baltica 9+ cluster, enabling a combined offshore wind development of around 1.3 GW with secured revenue streams from both the Phase I and Phase II regimes.
