Bałtyk 3

Offshore site preparation for Bałtyk 3 began in January 2026 with the launch of a subsea rock installation campaign in the Baltic Sea. Equinor and Polenergia deployed specialised vessels to place more than one million tonnes of rock material on the seabed across the Bałtyk 2 and Bałtyk 3 lease areas. The rock berms protect export and inter‑array cable routes and the future turbine foundations from wave action and sea currents, improving long‑term integrity and stability. This work, executed by marine contractors including Van Oord using multiple vessels, represents the first major offshore construction activity at the Bałtyk 3 site and prepares the ground for subsequent foundation and cable installation campaigns.

Offshore construction at the Bałtyk 3 site (in the Polish exclusive economic zone of the Baltic Sea, 22 km off the coast near Łeba) commenced in January 2026 with the start of the subsea rock installation campaign. Van Oord deployed up to four rock-placement vessels to lay down more than one million tonnes of material to provide scour protection for the 50 monopile foundations and to stabilise the export and inter-array cable corridors ahead of cable lay. The wider 2026 offshore construction campaign — covering monopiles, transition pieces, selected offshore substation components and subsea cables — was scheduled to follow from spring 2026 using Heerema Marine Contractors' heavy-lift vessel Thialf and a fleet of more than 20 vessels in total. First power is expected in 2027 with full commercial operation in 2028.

By 2025, UXO survey work for the Bałtyk 2 and Bałtyk 3 offshore wind farms had progressed to an executed inspection of the seabed. The Polish research company MEWO conducted seabed inspections to identify potential unexploded ordnance and duds along the planned export cable routes. Completing this UXO survey represented a key safety step ahead of large‑scale offshore construction and cable installation for the projects, ensuring that hazardous remnants do not pose a risk to vessels, equipment or future operations.

In late October 2025 Smulders completed the first load-out and sail-away of transition pieces (TPs) for the Bałtyk 2 and Bałtyk 3 offshore wind farms, marking a key manufacturing milestone for the projects' 100-monopile foundation programme. The first TPs departed from Smulders' Hoboken yard in Belgium and were transported by barge in sets of four to the company's Vlissingen yard in the Netherlands for storage and final preparation ahead of offshore installation, which was scheduled to begin in spring 2026 using Heerema Marine Contractors' heavy-lift vessel Thialf. Each TP measures approximately 17 metres tall and weighs around 400 tonnes. Smulders, in consortium with Sif, is manufacturing the full 100-piece TP set across the two farms; for Bałtyk 3 this corresponds to the project's 50 monopile foundations supporting Siemens Gamesa SG 14-236 DD turbines. Secondary steel components for the TPs were produced at Smulders' Polish facilities in Żary, Niemodlin and Łęknica, reinforcing the local-content commitments of the Equinor/Polenergia joint venture.

By 3 July 2025, IQIP had completed transport of sixteen jacket pile grippers to Smulders’ production facility in Newcastle, UK, for integration into the jackets of the two offshore substations serving the Bałtyk 2 and Bałtyk 3 projects. The pile grippers will maintain jacket position and create grouted connections during offshore installation, ensuring structural stability of the OSS platforms. This delivery marks a manufacturing and logistics milestone for Bałtyk 3’s substation foundation components.

By late June 2025, Polish companies Enprom and Tele‑Fonika Kable had been selected to supply and implement the onshore export cable system for the Bałtyk 2 and Bałtyk 3 offshore wind farms. Tele‑Fonika Kable will manufacture the high‑voltage power cables, while Enprom will prepare the dedicated onshore cable routes forming a roughly 14 km land connection corridor. This combination secures local manufacturing and installation capability for the onshore export cables serving Bałtyk 3.

By late June 2025, preparatory onshore works for the Bałtyk 2 and Bałtyk 3 offshore wind farms’ export cables were underway near Ustka. Within a roughly 14 km onshore connection corridor, Polish contractors were building cable routes and executing trenchless drilling at the landfall using Horizontal Directional Drilling (HDD) technology, allowing the export cables to be installed underground without open trenches. These HDD works and corridor preparations form a key onshore site‑preparation phase for Bałtyk 3’s grid connection ahead of full onshore cable installation and substation construction.

Onshore construction for the Bałtyk 3 offshore wind farm, developed jointly by Equinor and Polenergia, started in the second quarter of 2025. According to the developers, work had already begun by late June on two onshore substations near Ustka, the onshore cable corridor linking the coast to the national grid, and a new operations and maintenance base in Łeba. These works are being executed in parallel for the twin Bałtyk 2 and Bałtyk 3 projects, marking the transition of the Phase I Baltyk projects into physical implementation on land.

Onshore export cable installation for Bałtyk 3 started by June 2025 as part of the shared onshore infrastructure for the Bałtyk 2 and Bałtyk 3 offshore wind farms. Work commenced on constructing approximately 14 km of onshore connection corridor from the landfall near Ustka to the new onshore substations, including trenching and preparing routes for high‑voltage circuits. Polish contractors Enprom and Tele‑Fonika Kable were engaged, with Enprom responsible for building the land cable lines and Tele‑Fonika manufacturing and supplying 220 kV and 400 kV onshore cables. By late June 2025, construction of these power‑cable routes was already underway, marking the effective start of the onshore cable installation campaign for Bałtyk 3.

In Sif’s February 2024 announcement of its monopile contract for Bałtyk 2 and Bałtyk 3, the company set out the planned manufacturing schedule for the foundations. Production of the 100 monopiles for the twin 720 MW projects is scheduled to start in the second quarter of 2025 and be completed in the first quarter of 2026, ahead of offshore installation and commissioning. This timetable underpins fabrication planning for foundations that will support the Siemens Gamesa SG 14‑236 DD turbines at the Bałtyk 3 site in the Polish exclusive economic zone of the Baltic Sea.

By 27 June 2025, Equinor and Polenergia had mobilised several Polish contractors for the onshore connection infrastructure serving the Bałtyk 2 and Bałtyk 3 export systems. Hitachi Energy was constructing two onshore power stations in Pęplin near Ustka with Erbud as a key civil‑works subcontractor, while Enprom and Tele‑Fonika Kable had been selected to manufacture cables and build the approximately 14 km onshore cable corridor linking the landfall to the substations and then to PSE’s Słupsk–Wierzbięcino substation. In the landfall area west of Ustka, Hanab acted as HDD contractor and ZRB Janicki provided design services for the trenchless shore crossing used by the export cable systems, including Bałtyk 3 Export.

On 23 May 2025, Equinor and Polenergia reported that they had reached financial close for the Bałtyk 2 and Bałtyk 3 offshore wind projects. The partners secured two project finance packages, each of over EUR 3 billion including ancillary facilities, one for Bałtyk 2 and one for Bałtyk 3, with gearing of around 80%. In total, construction-period financing across both projects amounts to approximately EUR 7.2 billion. The lender group comprises about 30 financial institutions, including many of Equinor’s core relationship banks, the Nordic Investment Bank and the European Investment Bank. With financial close achieved, Bałtyk 3 has its full debt package in place, enabling large‑scale offshore and onshore construction underpinned by its long‑term CfD revenues.

Hellenic Cables was identified as the supplier of offshore export cables for the Bałtyk 2 and Bałtyk 3 offshore wind farms. In coverage of the projects’ financial close, the export cable scope is attributed to the Greek manufacturer, alongside Sif for foundations and Siemens Gamesa for turbines. The 720 MW Bałtyk 3 project will use these high‑voltage export cables to transmit power from its offshore substation to the onshore grid connection in Poland.

The Bałtyk 3 project, together with Bałtyk 2, secured long‑term debt support from the European Investment Bank (EIB) under the InvestEU framework. The EIB project sheet for “BALTYK II & BALTYK III OFFSHORE” shows a total EIB finance amount of EUR 1,003 million, with loan signatures on 20 May 2025 (two tranches of EUR 350 million each) and additional signatures on 14 November 2025 (EUR 148 million and EUR 155 million). The operation finances the design, implementation and operation of two fixed‑bottom offshore wind farms of up to 720 MW each off the Ustka‑Łeba coast. The EIB notes that the project supports EU energy and climate objectives and is located in a cohesion region. This development‑bank funding forms part of the wider project‑finance structure for Bałtyk 3 and its sister project.

On 20 May 2025, the Nordic Investment Bank (NIB) signed a EUR 126 million, 26-year loan agreement with MFW Baltyk II sp. z o.o. and MFW Baltyk III sp. z o.o., the special purpose vehicles for the Baltyk 2 and Baltyk 3 offshore wind projects developed by Equinor and Polenergia. The NIB financing supports construction of the two 720 MW offshore wind farms and their grid connection infrastructure in the Polish Baltic Sea, including the Baltyk 3 Export transmission system comprising the offshore substation, submarine export cables, and onshore cable corridor to the national grid. The loan was part of the broader EUR 7.2 billion syndicated project finance package involving approximately 30 financial institutions that reached financial close on 23 May 2025. NIB participation reflects the Nordic development finance institution mandate to support green infrastructure projects with significant environmental benefits in the Baltic region.

As part of preparatory works for Bałtyk 3 and its sister project Bałtyk 2, DeepOcean and subcontractor MEWO planned to start UXO-related seabed mapping campaigns in early 2025, using the vessel Amber Cecilia to survey the export and inter-array cable corridors for potential unexploded ordnance.

The General Directorate for Environmental Protection (GDOŚ) in Poland published national guidelines on the environmental impact assessment of offshore wind farms, which apply to all Polish projects including those developed by Polenergia and Equinor. The document classifies offshore wind farms as projects that "always significantly affect" the environment, making a full environmental impact assessment (EIA) mandatory due to potential impacts on marine ecosystems, natural resources and biodiversity. GDOŚ clarifies that, within areas already covered by location permits (PSZW), it is possible in the EIA process to require limiting the built-up portion of the permitted area with wind farm elements if this is the only way to minimise significant negative effects. The guidance stresses that such restrictions should be a last resort, after assessing alternative mitigation options, and that cumulative impacts with other projects must also be considered.

DeepOcean was awarded a subsea survey contract for the Bałtyk 2 and Bałtyk 3 offshore wind developments in Poland, with Polish firm MEWO acting as subcontractor. Under the contract, DeepOcean will conduct geophysical seabed surveys of the export and inter‑array cable corridors using a dedicated survey ROV, and will map the seabed for potential unexploded ordnance (UXO). Survey campaigns are scheduled for early 2025, with DeepOcean’s vessel Edda Flora to be mobilised for the main scope and MEWO deploying the vessel Amber Cecilia for UXO work. This contract secures specialist survey capabilities required to finalise detailed routing and installation planning for Bałtyk 3’s subsea cables.

Equinor and Polenergia commenced geophysical seabed survey activities for the Bałtyk 3 (and sibling Bałtyk 2) export and inter-array cable corridors in December 2024 under a contract with DeepOcean. The flagship survey vessel Edda Flora was mobilised to perform the main scope of work, deploying a dedicated survey remotely operated vehicle (SROV) to map the seabed and finalise the cable-corridor design. The scope ran in parallel with the UXO sub-campaign delivered by Polish subcontractor MEWO S.A. using the vessel Amber Cecilia. These activities supported safe and efficient subsea cable installation, and were a prerequisite for the January 2026 start of subsea rock installation along the cable corridors.

Equinor and Polenergia's Bałtyk 3 (and sibling Bałtyk 2) offshore wind farms commenced UXO mapping activities in December 2024 as part of the wider DeepOcean subsea-survey programme covering the export and inter-array cable corridors. The UXO sub-scope was delivered by Polish subcontractor MEWO S.A. using the vessel Amber Cecilia, with DeepOcean as the prime contractor. The work cleared the cable-corridor seabed of unexploded ordnance ahead of cable lay, and was a prerequisite for the January 2026 start of subsea rock installation along the Bałtyk 3 export cable corridor.

Tele‑Fonika Kable, a Polish cable manufacturer, was contracted to design, produce and deliver onshore export cables for the Bałtyk 2 and Bałtyk 3 offshore wind farms. For the two projects, Tele‑Fonika will supply approximately 85 km of 220 kV HV onshore export cables connecting the offshore substations to the onshore substations, and about 38 km of 400 kV EHV cables linking the onshore substations to the PSE Słupsk Wierzbięcino grid substation. All cables will be manufactured at the company’s Bydgoszcz plant before transport to the Polish coast for installation. This award designates Tele‑Fonika as the primary onshore high‑voltage cable supplier for Bałtyk 3.

Equinor and Polenergia awarded the Smulders–Sif consortium a contract to manufacture 100 transition pieces for the Bałtyk 2 and Bałtyk 3 offshore wind farms. These steel structures connect the monopile foundations to the turbine towers, with 50 units allocated to each project. The work includes fabrication of the complete transition‑piece structures with equipment, with part of the steelwork to be produced at Smulders’ facilities in Żory, Poland. This contract secures the secondary‑steel foundation components required to install the 50 Siemens Gamesa turbines planned for Bałtyk 3.

Iemants, a subsidiary of Smulders, was selected to design and construct two offshore substations for the Bałtyk 2 and Bałtyk 3 projects. The contract covers engineering, procurement, construction, testing and commissioning of two OSS platforms, each consisting of a topside and jacket structure. These substations will collect power from the turbine arrays and export it to shore via high‑voltage export cables. The award secures a key supplier for the offshore transmission infrastructure of the 720 MW Bałtyk 3 wind farm.

In September 2024, Equinor and Polenergia awarded a major onshore cable installation contract to Polish company Enprom for the Bałtyk 2 and Bałtyk 3 offshore wind farms. Enprom, one of Poland’s leading power construction firms, will be the main contractor for four 220 kV cable routes of about 7 km connecting the offshore export cables to the onshore substations, and two 400 kV routes linking the substations to the PSE grid substation over more than 6 km, including associated fibre‑optic telecoms. This contract covers design and installation of key onshore transmission infrastructure serving Bałtyk 3.

In early July 2024 the Pomeranian Voivode granted a building permit for sections of two offshore export cables for the Bałtyk 3 offshore wind farm, including their route to the transition joint bays (TJB) and two horizontal drillings. This decision complements the main turbine building permit by authorising key parts of the export cable system within the territorial sea and landfall area, enabling implementation of the project’s connection infrastructure to shore.

The Bałtyk 3 offshore wind farm obtained its main construction consent when the Pomeranian Voivode issued a building permit on 11 July 2024. The decision authorises the construction of 50 offshore wind turbines together with the associated internal electrical and telecommunications network, located in Poland’s exclusive economic zone of the Baltic Sea. This permit provides the core legal basis to start offshore construction of the generating infrastructure for the 720 MW MFW Bałtyk 3 project.

On 3 July 2024, Equinor and Polenergia signed contracts with Heerema Marine Contractors covering the transport and installation of foundations and offshore substations for the Bałtyk 2 and Bałtyk 3 offshore wind farms. Heerema will transport and install 100 monopiles, transition pieces and two offshore transformer stations at the project sites using heavy‑lift vessels, including the crane ship Thialf, during the 2026–2027 offshore campaigns. This EPCI‑style contract secures the main installation contractor for Bałtyk 3’s foundations and OSS platforms.

For the Bałtyk 3 project’s grid connection infrastructure, MFW Bałtyk III Sp. z o.o. submitted an application on 18 April 2024 for a building permit covering sections of two offshore export cables leading towards the transition joint bays (TJB) and associated horizontal directional drillings. The application, handled by the Pomeranian Voivode, relates to cable sections on specified land parcels near Lędowo, internal marine waters and the territorial sea, and is part of the broader project "Budowa infrastruktury przyłączeniowej morskiej farmy wiatrowej MFW Bałtyk III".

The project company MFW Bałtyk III Sp. z o.o. submitted an application for a building permit covering 50 offshore wind turbines together with the internal electrical and telecommunication network for the Bałtyk 3 offshore wind farm. The application, lodged on 10 April 2024 with the Pomeranian Voivode, sought authorisation to construct these installations within Poland’s exclusive economic zone of the Baltic Sea.

On 25 March 2024, Equinor and Polenergia signed final contracts with Rambøll for detailed design and foundation engineering for the Bałtyk 2 and Bałtyk 3 offshore wind farms. The Danish engineering firm will develop and engineer the monopile foundations for all 100 turbines across both projects. This award provides Bałtyk 3 with specialist structural and geotechnical design services for its monopile foundations, representing a key late‑development engineering milestone ahead of fabrication and offshore installation.

Sif Holding NV and the Equinor–Polenergia joint venture finalised contracts for the supply of 100 monopile foundations for the Bałtyk 2 and Bałtyk 3 offshore wind farms. The monopiles will support 50 turbines at each project, together totalling 1.44 GW, and will be installed in the Polish exclusive economic zone of the Baltic Sea about 37 km and 22 km from the coast near Łeba. Manufacturing of these large‑diameter monopiles will take place at Sif’s facilities in the Netherlands, forming a core part of the foundation package for Bałtyk 3 and its sister project.

In 2023 Seaway7 secured an EPCI contract covering the 66 kV inter‑array cable systems for the Bałtyk 2 and Bałtyk 3 offshore wind farms. The scope comprises engineering, procurement, construction and installation of 100 inter‑array cables with a total length of about 200 km, linking the Siemens Gamesa turbines to the offshore substations. The contract, awarded for the twin 720 MW projects in the Polish exclusive economic zone of the Baltic Sea, positions Seaway7 as the main contractor for submarine array cabling, with offshore installation campaigns scheduled for the mid‑2020s as part of the overall construction programme.

Equinor and Polenergia awarded Hitachi Energy the contract to deliver the electrical systems infrastructure for the Bałtyk 2 and Bałtyk 3 offshore wind projects. Hitachi Energy is responsible for overall electrical system design from the turbines to the grid connection at the PSE Słupsk‑Wierzbięcino substation, including system studies, the overall power control system, telecoms network, and all high‑voltage equipment at both offshore and onshore substations. The scope also includes turnkey delivery of the entire onshore substation and interface works at the grid connection point. This contract secures a key substation and electrical infrastructure partner ahead of FID for both 720 MW projects.

On 8 November 2022 the Regional Directorate for Environmental Protection in Gdańsk (RDOŚ Gdańsk) issued an amended Decyzja środowiskowa (DŚU) for the MFW Bałtyk III offshore wind farm. The amendment was required because Bałtyk III's turbine parameters had changed materially compared with the original 2017 environmental decision — moving to the Siemens Gamesa SG 14-236 DD platform — and the developer (Polenergia, with Equinor as JV partner) had filed an application to amend the 2017 decision on 13 June 2022. The amended DŚU became final on 29 November 2022, completing the renewed environmental-conditions framework needed to build Bałtyk III at the updated technical specification. Per the Polish convention, DŚU amendments re-emit eia_approved rather than routing through consent_variation_awarded (which is reserved for Pozwolenie na budowę amendments). This decision unlocked subsequent procurement decisions and the 2025 final investment decision and financial close.

On 2 June 2022 the Bałtyk III project company submitted a new Decyzja środowiskowa (DŚU) application to the Regional Directorate for Environmental Protection, covering the shared grid-connection infrastructure for the Bałtyk II and Bałtyk III offshore wind farms. The application was triggered by significant modifications to the connection infrastructure as the project matured, particularly on the onshore section including spatial route changes for the export cable corridor and onshore substation locations. This filing is distinct from the September 2019 EIA submission (which covered the Bałtyk III wind farm turbines following turbine-parameter changes) and from the November 2022 amended decision (which closed the wind-farm DŚU loop). The connection-infrastructure DŚU procedure ran in parallel and underpinned the export and onshore cable corridor design that subsequently fed into the procurement awards to Hellenic Cables/Jan De Nul (export), Tele-Fonika Kable (onshore cables), ENPROM (cable corridor preparation), Hanab and ZRB Janicki (HDD landfall). Sister project Baltica 3 records its own connection-infrastructure DŚU as a separate eia_approved event under the same PL routing convention.

Equinor and Polenergia selected Siemens Gamesa as the turbine supplier for the Bałtyk 2 and Bałtyk 3 offshore wind farms. A signed preferred-supplier agreement covers delivery of SG 14‑236 DD direct-drive offshore wind turbines, each with a nominal capacity of 14 MW and up to 15 MW with Power Boost. The agreement is described as a key milestone for the Phase I projects MFW Bałtyk II and MFW Bałtyk III and secures access to large, modern machines for the twin 720 MW wind farms in the Polish exclusive economic zone of the Baltic Sea. The selection aims to bring proven offshore turbine technology into the Polish market and support development of the local supply chain around these projects.

The maritime area where the MFW Bałtyk III offshore wind farm will be built was designated for offshore wind use in Poland’s national maritime spatial plan (PZP POM), adopted by the Council of Ministers in June 2021. The plan allocates parts of the Polish Exclusive Economic Zone, including the Słupsk Bank and surrounding shoals, for offshore wind development. Bałtyk III is located in this Polish EEZ area off Łeba, within the zone defined by the plan for offshore wind farms, providing the overarching spatial planning basis for the project’s PSZW seabed permit and subsequent consents.

In May 2021, the Bałtyk 3 offshore wind farm, developed by Equinor and Polenergia alongside the twin Bałtyk 2 project, received decisions from Poland’s Energy Regulatory Office (URE) granting the right to cover the negative balance for electricity generated and fed into the grid. This marks the formal eligibility of Bałtyk 3 for support under Poland’s Phase I offshore wind Contract for Difference (CfD) regime established by the Offshore Wind Promotion Act. The decision applies jointly to Bałtyk 2 and Bałtyk 3, together totalling about 1,440 MW, and is a prerequisite for determining the project’s final CfD settlement price. It effectively secures the project’s access to a 25‑year support mechanism, underpinning bankability and enabling further development towards investment decision and construction.

Bałtyk 3 secured its main revenue support in May 2021 when it, together with Bałtyk 2, was awarded a 25‑year Contract for Difference (CfD) by Poland’s Energy Regulatory Office. The CfD award locks in support for 1,440 MW of capacity across the two projects, providing long‑term price stability for electricity sold into the Polish power market. Equinor later stated that the CfDs for Bałtyk 2 and 3 secure power prices at approximately EUR 71/MWh in 2021 prices, indexed to inflation, for the full 25‑year support period. This revenue framework is the cornerstone of the project’s financing, underpinning subsequent FID, debt raising and construction for Bałtyk 3.

Between 2017 and 2019, the Bałtyk III project undertook a dedicated wind measurement campaign to assess the offshore wind resource at the site. These measurements, conducted over three years, were used to characterise wind conditions and support energy yield calculations and technical and financial feasibility assessments for the planned offshore wind farm.

On 25 September 2019, the Bałtyk III project company submitted a new environmental application to the Regional Director for Environmental Protection in Gdańsk. The application sought a fresh environmental decision (DŚU) covering updated technical parameters of the offshore wind turbines planned for MFW Bałtyk III. This filing marked the start of a supplementary environmental assessment process to align the consented design with newer turbine specifications, following the original DŚU issued in 2016.

Between 2017 and 2019, the Bałtyk III project undertook wind measurement campaigns to characterise the local wind resource and support energy yield assessments. These wind measurements are listed among completed project development activities in the supply chain plan. The multi‑year data collection provided the resource basis for technical and financial feasibility analyses, turbine selection and layout optimisation for the 720 MW offshore wind farm located about 22 km off Łeba in the Polish Exclusive Economic Zone.

In 2017 the Bałtyk III developer completed desktop analyses to understand technical and supply‑chain constraints relevant to the project. The work included a preliminary supply chain analysis and a SWOT analysis of the potential of Polish seaports to serve as ports supporting the MFW Bałtyk II and MFW Bałtyk III projects. These studies mapped logistical and infrastructure opportunities and limitations, such as port capabilities for installation and O&M support, and informed later procurement and localisation strategies for the Phase I Bałtyk projects.

In 2017 the Bałtyk III developers carried out preliminary geological investigations of the seabed at the planned offshore wind farm area. These geotechnical surveys examined seabed conditions to inform the design and optimisation of foundations and subsea infrastructure. Completion of the preliminary seabed investigations provided an initial understanding of soil conditions and constraints for future detailed geotechnical campaigns and engineering design.

In 2017, as part of preparing MFW Bałtyk III (together with Bałtyk II), the project sponsors completed preliminary supply‑chain and port capability analyses. This work included a SWOT analysis of the potential of Polish seaports to act as service and installation ports for the Bałtyk II and Bałtyk III offshore wind farms. The studies helped identify how domestic port infrastructure and related industries could support construction and operation of the projects and where strengths, weaknesses and investment needs lay.

According to the 2021 supply chain plan for the MFW Bałtyk III offshore wind farm, the project obtained its formal environmental decision (decyzja o środowiskowych uwarunkowaniach) in 2016. This decision followed earlier development activities including environmental surveys carried out between 2012 and 2014. The environmental decision sets binding environmental conditions for the 720 MW wind farm and its grid export infrastructure and is a prerequisite for subsequent construction permitting, such as building permits and cable consents.

In 2014, the MFW Bałtyk III project concluded a grid connection agreement ("Umowa przyłączeniowa") for its planned 720 MW offshore wind farm in the Polish Exclusive Economic Zone of the Baltic Sea. This agreement built on the earlier grid connection conditions issued in 2012 and formally committed the project and the transmission system operator to the agreed connection point and capacity. Securing the connection agreement was a key regulatory and commercial prerequisite for advancing Bałtyk III toward subsequent permitting, contract awards and, later, construction.

The MFW Bałtyk III project secured a permit for laying and maintaining submarine cables for its grid connection infrastructure in 2014. This permit authorises the installation and long‑term presence of the offshore export cable system required to evacuate power from the wind farm area to shore, and was one of several key early regulatory milestones achieved by the project alongside its grid connection conditions and environmental decision.

By 2014 the baseline environmental survey campaign for the MFW Bałtyk III site had been completed. Over the period 2012–2014, the project company carried out environmental studies in the Baltic Sea area earmarked for the wind farm. The completion of these surveys provided essential input data on environmental conditions and sensitivities, supporting the project’s subsequent environmental impact assessment and regulatory processes.

In 2012, the MFW Bałtyk III offshore wind farm obtained formal grid connection conditions ("warunki przyłączenia do sieci") for its planned 720 MW installation. These connection conditions, issued following an application to the transmission system operator, define the technical and operational requirements for linking the project and its export infrastructure to the Polish high‑voltage network. Securing these conditions is a key regulatory milestone in Poland, as it confirms that the system operator has assessed and reserved network capacity for the project and sets the framework within which the subsequent grid connection agreement can be concluded.

The Bałtyk III offshore wind project obtained its key seabed-rights instrument, the PSZW (permit for the construction and use of artificial islands, structures and devices in Polish maritime areas), in 2012. This permit, issued under the Maritime Areas Act by the competent minister, designates the offshore area for the project and authorises construction and use of turbines and associated infrastructure in the Polish Exclusive Economic Zone. It is cited in the project’s development-stage documentation as the first major permit obtained, underpinning subsequent grid connection agreements, environmental decision, and detailed design and survey campaigns.

As part of early development for the MFW Bałtyk III offshore wind farm, the developers initiated baseline environmental surveys in 2012. These multi‑year investigations were designed to characterise the marine environment in the Polish Exclusive Economic Zone where the project will be located. The work marked the start of a structured environmental data‑collection programme feeding into permitting and impact assessment for the project.

In 2012, the MFW Bałtyk III offshore wind farm secured formal grid connection conditions ("Warunki przyłączenia do sieci"), marking one of the earliest such milestones among Polish offshore wind projects. The conditions defined the technical and commercial framework for connecting the planned 720 MW wind farm in the Polish Exclusive Economic Zone of the Baltic Sea to the national transmission system, providing clarity on connection point and parameters needed to progress permitting, design and financing. This early grid milestone helped establish Bałtyk III as one of the most advanced offshore wind developments on Polish maritime areas at the time.
