This spring, the Swedish government granted permission for the submarine cables for Kattegatt Syd, both export and inter-array, as well as detailed seabed surveys of the project site. Vattenfall has also secured the necessary network concession for the laying and operation of offshore and onshore export cables.

The construction and operation of the 1.2 GW offshore wind farm were authorised in May 2023.

In the fourth quarter of last year, Vattenfall carried out geophysical and geotechnical investigations within the array site and the export cable corridor, which provided the basis for detailed design of the project, selection of foundation type and appropriate installation technology for foundations and cables.

From August to November 2025, the developer will perform archaeological investigations at the wind farm site and along the export cable route.

The company will also be carrying out surveys onshore, including a test drilling at the landfall site west of Stavder.

The 1.2 GW Kattegatt Syd project is planned to comprise 60-80 wind turbines mounted on fixed-bottom foundations.

The offshore wind farm is expected to be able to generate around 5 TWh of electricity annually once operational. Vattenfall anticipates that Kattegatt Syd will be in operation in the early 2030s.
