Baltic Power, a joint venture between PKN ORLEN and Northland Power, has issued a tender for the onshore grid connection assets for its Baltic Power offshore wind farm. It concerns onshore cable lines, onshore substation and overhead lines connecting the project with the national grid in the Choczewo commune in Northern Poland.

The 6.5 km onshore cable route will be routed via underground single-core AC cables with an operating voltage of 220 kV or 275 kV. The onshore cable route starts at the Transition Joint Bays located near shore, through forest area and terminates at the Baltic Power high voltage onshore substation, from which power will be transferred to National Grid via 400 kV overhead lines. The onshore substation will be equipped with reactive power and voltage control equipment to ensure compliance with Polish Grid-Code requirements.

The Baltic Power project is planning to select an EPC contractor to execute the wind farm's full scope of onshore grid connection assets. The EPC contract includes:

  • Construction of all components including overhead lines to SE Choczewo Substation in accordance with Polish construction laws.
  • Delivery, installation, and commissioning of all equipment required
  • Detailed design and technical analyses required to complete contract
  • Performance of all other works relating to the connection of the Offshore Wind Farm to the National Power System (NPS), ensuring compliance with the issued Grid Connection Conditions (GCC)
    Interested parties are to submit applications by 18:00 CET Tuesday, 14th September.

    PKN ORLEN and Northland Power are jointly developing the site to host an array with a total capacity of up to 1.2 GW. Construction is expected to commence in 2023 with commercial operations expected in 2026. Last month Poland’s Energy Regulatory Office approved a Contract for Difference for the
    Baltic Power offshore wind farm which was priced PLN 319.60 per MWh for up to 25 years, subject to some adjustments and final approval from Polish authorities and the European Commission.
