Contract Details
Description
Prysmian supplied the export cable system for the first phase of the Walney Offshore Wind Farm, whose 132 kV transmission assets were subsequently transferred into the Walney 1 OFTO. The company was awarded a €24.5 million contract for the first-phase export cables, providing the high‑voltage links between the offshore substation and the onshore grid connection near Heysham. This construction‑phase scope covered manufacture and supply of both the submarine export cable and associated land cable sections for the 132 kV HVAC connection commissioned by DONG Energy. The work formed the core transmission circuit later owned and operated by Blue Transmission Walney 1 Ltd as the Walney 1 OFTO.
