Contracts have been signed for the offshore transmission infrastructure of the 1,140MW Baltic Power offshore wind farm after Orlen Group announced on 11 October its final investment decision to build the project.

JDR Cables will design and manufacture 66kV inter-array cables for the 1,140MW Baltic Power offshore wind farm at its factory in Hartlepool, UK (pic credit: JDR Cables)

Developed in partnership with Canada’s Northland Power, the first wind farm in the Polish Baltic Sea will be located 23 kilometres off the coastline and will feature 76 wind turbines, each with a power rating of 15MW. The project is scheduled to be fully operational by 2026.

Baltic Operator, a subsidiary of Grupa Przemysłowa Baltic, will manufacture two offshore substations for the project. Production of the offshore substations is due to start this month at Grupa Przemysłowa Baltic’s production facilities in Gdansk and Gdynia.

A consortium comprising Tele-Fonika Kable and JDR Cable Systems – both part of TFK Group – and partners NKT and Deme Offshore will design, manufacture and install 340 kilometres of land and subsea cables.

TFK will manufacture and install 230kV land power cables and cores for inter-array cables at its manufacturing facility in Bydgoszcz. As a consortium partner, NKT will develop the offshore export cables that will deliver power from the offshore substations to the shore. 

At its Hartlepool facility in the UK, JDR will design and manufacture 66kV inter-array cables that will be used to connect the 76 turbines to the offshore substation. Deme Offshore will be responsible for the transport and installation of all subsea cables.

The manufacture and delivery of all cables will be completed by the end of 2025.
