The recent award to SPIE Wind Connect to work on the Baltyk II wind farm and Baltyk III represents substantial technical validation in the Baltic Sea. Seaway7 has entrusted the company to carry out the termination and testing of the 66 kV cable network that will connect the wind turbines to the offshore substations.
The 66 kV cable network will connect the offshore substations
The technical specifications of the deployment have enabled the main offshore campaign to be scheduled to start in the second quarter of 2026. The wind farms have a combined capacity of 1,440 MW to supply more than two million Polish households.
The engineering design includes ten strings of five wind turbines connected by conductors of different cross-sections. The configuration uses 400 mm² cables for the outer wind turbines and 1,000 mm² cables to carry the full load to the control stations.
In addition, the experience of Mike Senior and his technical team ensures that each connection meets the most stringent safety standards in the offshore wind sector. SPIE’s involvement increases the reliability of Poland’s national power grid at an important time for energy autonomy. Likewise, the technical deployment demonstrates superior management capability in marine environments with high logistical and environmental complexity.
The industry impact will enable Poland’s Exclusive Economic Zone to become established as a key hub for the development of clean energy. The strategic collaboration between SPIE and Seaway7 is essential to the operational success of these facilities. Proper execution of the interconnected cable tests will allow the generation infrastructure to reach its maximum commercial potential without technical setbacks during commissioning.
