Equinor and Polenergia's Bałtyk 2 and 3 offshore wind farms begin the construction phase on their official website
**Construction Phase Overview of Bałtyk 2 and Bałtyk 3 Offshore Wind Farms**
Equinor and Polenergia, joint developers, are progressing with the construction of Bałtyk 2 and Bałtyk 3 offshore wind farms in the Baltic Sea, Poland. Here is a summary of the project's construction phase, including manufacturers, contractors, timeline, and expected electricity production:
### Manufacturers and Contractors
- **Wind Turbines**: Siemens Gamesa will supply the wind turbines for both Bałtyk 2 and Bałtyk 3 [4]. - **Foundations**: Ramboll is responsible for the design, while Sif Group and Smulders are involved in the manufacturing. Heerema will handle the installation [4]. - **Inter-array Cables**: Seaway7 has been contracted for the installation of these cables [4]. - **Export Cables**: Jan De Nul and Hellenic Cables are responsible for this component [4]. - **Electric System Infrastructure**: Hitachi Energy is the selected supplier [4]. - **Offshore Substations**: Ramboll IEMANTS (Smulders) is involved in design and manufacturing, with Heerema handling installation [4]. - **Onshore Cables**: Enprom and Telefonika are the contractors for this part [4].
### Timeline
The construction timeline for Bałtyk 2 and Bałtyk 3 is currently in active development, with the Nordic Investment Bank (NIB) providing financing for the construction and operation of these wind farms [1].
### Expected Electricity Production
- **Capacity**: Each farm will have a capacity of **720 MW**, totaling **1440 MW** for both projects [1]. - **Energy Output**: Together, they will generate over **4,900 GWh** of electricity annually [1]. - **Household Supply**: This is enough to supply electricity to around **2 million average Polish households** [1].
### Funding and Partnerships
The projects are supported by a EUR 126 million financing package from NIB, consisting of two 26-year loans of EUR 64 million and EUR 62 million, respectively [1]. This funding provides long-term capital and a diversified funding base for the construction and operation phases.
The ceremony for the start of construction works on the onshore power infrastructure for Bałtyk 2 and Bałtyk 3 was held on 26 June in Warsaw. Obtaining building permits and making the final investment decision for Bałtyk 1 is planned for 2027.
The Polish company Erbud is a key subcontractor for construction works on the onshore substations for Bałtyk 2 and Bałtyk 3. Horizontal directional drilling technology is being used to lay cables underground without the need for an open trench, with Hanab as the contractor, and ZRB Janicki responsible for the project.
Hitachi Energy is responsible for the construction of the onshore substations for Bałtyk 2 and Bałtyk 3, with a significant part of the advanced equipment to be manufactured in its facilities in Łódź. Enprom and Tele-Fonika have been selected for the delivery of cables and the preparation of special cable routes for Bałtyk 2 and Bałtyk 3.
Preparations for offshore construction for Bałtyk 2 and Bałtyk 3 are underway, with work related to the removal of subsea boulders from the future export cable route to begin soon. Offshore works, including the installation of monopiles, for Bałtyk 2 and Bałtyk 3 are scheduled for the first half of 2026. The first electricity from the Bałtyk 2 and Bałtyk 3 offshore wind farms is expected in 2027, with full commercial power production from both farms scheduled for 2028. The construction of routes for power cables for Bałtyk 2 and Bałtyk 3 is underway, with the onshore connection corridor spanning approximately 14 kilometres. Two onshore substations are being built in Pęplino near Ustka for Bałtyk 2 and Bałtyk 3.
The Bałtyk 1 wind farm, another significant offshore project in the Polish Baltic Sea, is expected to enter the commercial phase in 2032. A supply chain plan for the Bałtyk 1 wind farm is ready, according to the developers.
- Investment in the technology industry is evident in the selection of Hitachi Energy for the construction of the onshore substations, with a part of the advanced equipment to be manufactured in their facilities in Łódź.
- The finance industry is involved in the projects' funding, with the Nordic Investment Bank providing financing for the construction and operation of Bałtyk 2 and Bałtyk 3 offshore wind farms.
- The energy sector is a significant focus of the construction of Bałtyk 2 and Bałtyk 3 offshore wind farms, with each farm expected to generate 4,900 GWh of electricity annually and have a capacity of 720 MW, totaling 1440 MW for both projects.
