Orlen Neptun IV is a planned ~1.2 GW offshore wind farm sited on the Odra Bank (plot 14.E.4) in the Polish Baltic Sea, held in a dedicated SPV. It is the largest single Phase‑III lot awarded to the ORLEN Group on the Odra Bank and forms part of the Baltic West cluster of adjacent concessions. The...

By 8 May 2026, ORLEN Neptun was carrying out marine environmental surveys for the Baltic West offshore wind project, which comprises four concessions on the Odra Bank including Orlen Neptun IV in area 14.E.4. The surveys are described as an integral part of preparing the offshore wind farm for the construction phase and its subsequent operation in line with defined environmental standards. Work in the planned project area focuses on characterising marine ecosystems and environmental conditions to feed into impact assessments, design choices, and mitigation measures for Baltic West and thus for Orlen Neptun IV as one of its constituent sites.
On 30 April 2026, ORLEN Neptun launched a 2D seismic survey campaign for the Baltic West offshore wind project, of which Orlen Neptun IV (location 14.E.4 on the Odra Bank / Ławica Odrzańska) is one of four concessions. The work is carried out by the Polish geophysical services company Geofizyka Toruń using multi-channel high-resolution 2D seismic methodology. The scope comprises acquisition of approximately 3,000 kilometres of seismic lines investigating the geological structure of the seabed down to a depth of around 100 metres. The campaign is expected to last several months and the data will be used by ORLEN Neptun to prepare further survey campaigns and to support design analyses at subsequent stages of the four Baltic West projects, including Orlen Neptun IV. This marks the start of the formal geophysical site-investigation phase for the 14.E.4 area following the 2023 PSzW seabed-siting decision and the cluster-wide preparatory work already underway.

ORLEN Neptun signed a land reservation agreement with the Kołobrzeg Seaport Authority to prepare a dedicated service port for the Baltic West offshore wind project, which comprises four concessions on the Ławica Odrzańska bank, including the 14.E.4 area held by Orlen Neptun IV. The agreement reserves land within the Port of Kołobrzeg so that detailed analyses and pre-project documentation can be carried out, allowing the parties to design solutions best suited to servicing the Baltic West offshore wind farm. Kołobrzeg is identified as the closest and therefore optimal port location for servicing this second-phase ORLEN Group offshore wind development. This marks a late-stage development milestone for the Baltic West concessions, including Orlen Neptun IV, by securing a future O&M base ahead of construction.
On 22 January 2026, ORLEN Neptun signed a reservation agreement with the Kołobrzeg Seaport Authority covering land in Kołobrzeg port for development of a service port to support the Baltic West offshore wind project. Baltic West comprises four concessions on the Ławica Odrzańska (Odra Bank), including area 14.E.4 held by an ORLEN Neptun subsidiary and developed as Orlen Neptun IV. The land reservation enables detailed analyses and pre‑project documentation for a dedicated operations and maintenance base located at the closest suitable port to the project area. This early development milestone underpins long‑term O&M logistics for Orlen Neptun IV and the wider Baltic West cluster, improving service access by crew transfer vessels and supporting future offshore wind projects in this part of the Baltic Sea.

On 10 June 2025, ORLEN Neptun (part of the ORLEN Group) officially launched the Świnoujście Offshore Terminal — Poland's first dedicated offshore-wind installation and marshalling port. The terminal is shared port infrastructure intended to serve the ORLEN offshore portfolio: currently used by Baltic Power (installation campaign in progress) and planned to serve the Baltic West cluster (incl. this project's licence on the Odra Bank) when those projects reach their preassembly phase. Recorded on this project as a cluster-port infrastructure milestone, not as project-specific preassembly site readiness — the terminal opening is part of the broader development context, not a construction milestone for this lot. — original event description (preserved verbatim) — On 10 June 2025, ORLEN Neptun, part of the ORLEN Group, officially launched the Świnoujście Offshore Terminal in the port of Świnoujście. The facility is described as Poland’s first offshore wind farm installation terminal and one of the most advanced in Europe. It has been designed to accommodate the largest jack‑up and heavy‑lift vessels used for installing offshore wind turbines of around 15 MW, and to handle unloading, stacking and loading of monopile foundations, towers, blades, nacelles and cabling, as well as very heavy offshore substation topsides. ORLEN states that the terminal will primarily support installation of components for the Group’s offshore wind projects, including Baltic East and future developments. ORLEN Neptun’s four Phase II Odra Bank locations (14.E.1–14.E.4) are situated near Świnoujście, where this installation terminal is located, so the readiness of the terminal is a key preassembly and logistics milestone for the Baltic West cluster, including the Orlen Neptun IV (14.E.4) project.
Following the competitive Phase II adjudication, the Orlen Group received a final decision from Poland’s Minister of Infrastructure in October 2023 granting five new seabed licences for offshore wind farms with a total capacity of about 5.2 GW. These licences cover four locations on the Odra Bank, including area 14.E.4, and one site near Choczewo (46.E.1). Orlen Neptun’s corporate materials state that all four Odra Bank locations, including Orlen Neptun IV’s 14.E.4 plot of roughly 150 km² and about 1,200 MW potential capacity, "have already obtained the location permit (PSzW) and terms of connection". This Ministry decision constitutes execution of the PSzW seabed siting permit for Orlen Neptun IV, formally allocating the 14.E.4 area to the project SPV and securing long‑term rights to construct and operate artificial islands and structures there.
In October 2023, the Polish Minister of Infrastructure granted ORLEN Group five new seabed location permits (PSzW) for offshore wind farms in the Baltic Sea, including the 14.E.4 area that will host the 1,200 MW Orlen Neptun IV project on the Odra Bank near Świnoujście. These PSzW decisions, which authorise the erection and use of artificial islands, structures and equipment, together with preliminary grid connection terms already secured for all four 14.E locations, provide the regulatory basis for progressing Orlen Neptun IV towards participation in Poland’s offshore wind support scheme with an anticipated COD from 2034 onwards.
On 30 May 2023, Poland’s Ministry of Infrastructure published the results of six adjudication proceedings for Phase II offshore wind locations. In the competitive process for area 14.E.4 on the Odra Bank, the Orlen Group’s project company Orlen Neptun IV was ranked first. This ranking outcome effectively awarded Orlen Neptun IV priority rights to develop an offshore wind farm in the 14.E.4 zone, ahead of other bidders such as EDF Renewable Offshore Poland I and Antares Offshore Wind Farm. The decision marks the formal selection of Orlen Neptun IV as the winning applicant for this seabed area, enabling the project to progress towards execution of the siting permit (PSzW) and further early‑stage development activities within the Baltic West cluster.
