Baltica 2 Offshore Wind Farm is an offshore wind project located in the Baltic Sea, within Poland’s exclusive economic zone. It is part of the larger Baltica Offshore Wind Project, which also includes Baltica 3. The project is a joint venture between Ørsted and PGE Polska Grupa Energetyczna (PGE).
Project Details
Recommended White Papers
Baltica 2 is being developed approximately 40km off the Polish coastline in the Baltic Sea. It will feature 107 Siemens Gamesa 14 MW-222 wind turbines with a total capacity of up to 1.5GW.
The project will include the installation of 170km of 66kV subsea array cables that will connect the wind turbines to the offshore substations.
The generated electricity will be transmitted through offshore substations and connected to the onshore grid, expected to supply electricity to approximately 2.4 million Polish households. The final investment decision for the project was made in January 2025.
Baltica Offshore Wind Farm
The Baltica Offshore Wind Farm is a large-scale offshore wind project in the Polish section of the Baltic Sea. It consists of two phases, Baltica 2 and Baltica 3, developed as a 50/50 joint venture between Ørsted and PGE.
PGE plans to achieve climate neutrality by 2050, while Ørsted aims to reach 30GW of installed offshore wind capacity globally by 2030.
The partnership between Ørsted and PGE was established in 2019, with a joint venture agreement signed in May 2021 to develop the two phases. The project supports Poland’s 5.9GW offshore wind capacity target by 2030 and is part of efforts to transition from fossil fuels to renewable energy.
Baltica 2 Offshore Wind Farm Ownership and Developers
The project is owned and developed by Ørsted and PGE, each holding a 50% stake in the joint venture. Ørsted is a Denmark-based energy company with extensive experience in offshore wind farm development, while PGE is Poland’s energy utility, responsible for a significant portion of the country’s electricity generation.
Infrastructure and Technology
Baltica 2 will employ offshore wind turbines installed on fixed-bottom foundations. The turbines will be connected to offshore substations that will collect and convert electricity before transmission.
The project will incorporate high-voltage direct current (HVDC) technology to minimise energy loss during transmission.
Economic and Environmental Impact
Baltica 2 is expected to contribute significantly to Poland’s renewable energy supply, reducing dependence on fossil fuels. The project is projected to decrease carbon dioxide (CO₂) emissions by approximately five million tonnes annually.
Baltica 2 Offshore Wind Farm Financing Details
The project is supported by Poland’s Offshore Wind Act, providing financial incentives and regulatory frameworks for offshore wind development. Baltica 2 has been awarded a Contract for Difference (CfD), ensuring revenue stability.
The European Bank for Reconstruction and Development (EBRD) has approved up to €300m in long-term senior debt financing for the project, supporting both the construction and operation phases.
Contractors Involved
In April 2023, Ørsted and the PGE Group signed an agreement with Siemens Gamesa Renewable Energy for supplying offshore wind turbines for the Baltica 2 project.
In May 2023, a consortium made of Biuro Studiów, Projektów i Realizacji “Energoprojekt‐Katowice” SA and “Energopomiar” has been selected to serve as a contract engineer when constructing the land connection of the project. The consortium will supervise investor’s supervision over the work performed by the general contractor while building the line and the station parts of the onshore connection infrastructure.
In June 2023, the joint venture of PGE and Ørsted signed contracts with Navantia-Windar and Orient Cable (NBO) for the delivery of foundations and array cables for Baltica 2.
Semco Maritime and PTSC Mechanical & Construction (PTSC M&C) were awarded the contract in June 2023 for the design, manufacturing, and commissioning of offshore substations. The substations will be responsible for collecting electricity generated by the wind turbines and transmitting it to the onshore grid.
In September 2023, Boskalis received contracts for the transportation and installation of subsea export and array cables. The company is also responsible for seabed preparation activities, including levelling, pre-trenching, and boulder removal, to ensure a stable foundation for the wind farm’s components.
Steelwind Nordenham was contracted in October 2023 to supply monopile foundations for the wind turbines. These foundations will provide structural support and ensure the stability of the turbines in offshore conditions.
DNV was awarded the contract for component certification in December 2023. The company is responsible for ensuring that all major components of the wind farm meet industry standards and regulatory requirements before installation.
Fred. Olsen Windcarrier was selected in January 2024 to install 48 from 107 wind turbines for the Baltica 2 project. The company will use a specialised jack-up vessel to lift, position, and secure the turbines onto their designated foundations.
GE Vernova and Polimex Mostostal were chosen as the general contractors for onshore infrastructure construction in January 2024. Both firms are responsible for building electrical substations and transmission lines that will integrate the offshore wind farm with Poland’s national power grid.
In February 2024, PGE and Ørsted signed a contract with Van Oord for the transport and installation of 111 monopiles of Baltica 2. Of 111 monopiles, 107 will serve as foundations for wind turbines, and the remaining four will be used as foundations for offshore substations.
In February 2024, PGE and Ørsted finalised a contract with Cadeler for the installation of the second batch of turbines of the wind farm.
PGE and Ørsted signed a contract with a consortium of Polish companies – ROMGOS Gwiazdowscy and ZRB Janicki in February 2024 for the execution of steerable drilling under the beach necessary for routing 275 kV cable lines and the construction of ‘connection couplers’.
In September 2024, PGE, Ørsted, and Istrana signed a lease agreement for the future T5 terminal in the Port of Gdansk. The terminal will be used for the storage, pre-assembly and offshore installation of turbine components for the Baltica 2 project.
