System Testing

High‑voltage system testing of the 66 kV inter‑array cable network for the Bałtyk 2 offshore wind farm is scheduled to start in the second quarter of 2026. Spie, through its specialist unit Spie Wind Connect, has been contracted by Seaway7 to carry out termination and testing works on the inter‑array cable systems for both Bałtyk II and Bałtyk III. The scope includes terminating 66 kV cables linking strings of five turbines to the offshore substations and performing electrical tests to support final grid connection. The main offshore campaign for these activities is expected to begin in Q2 2026, ensuring that the internal collection network is properly commissioned ahead of turbine energisation.
