Prysmian has successfully completed the installation and testing of the export cables linking the Sofia offshore wind farm to the UK electricity grid. This project marks a breakthrough in subsea energy infrastructure, ensuring a robust connection for the supply of clean energy.
Submarine cable technology boosts clean energy
The development includes more than 440 kilometers of ±320 kV submarine cables with XLPE insulation, produced at its Pikkala plant (Finland), and another 15 kilometers of terrestrial cables of the same capacity, manufactured in Gron (France) using P-Laser environmentally friendly insulation.
This high-voltage link will enable the 1.4 GW farm to deliver enough power to meet the demand of approximately 1.2 million British homes . RWE, as the farm’s developer, contracted Prysmian in 2021 to carry out this critical mission for the country’s energy transition.
Submarine connection ready
The CLV Leonardo da Vinci was the key component of the underwater installation, strengthening the company’s capacity for complex offshore cable laying operations. This technical solution ensures efficient electrical transmission from the open sea to the onshore infrastructure.
The completion of this project strengthens the company’s position as a key player in the large-scale deployment of renewable energy and highlights the importance of advanced insulation technologies such as XLPE and P-Laser in subsea high-voltage systems.
With Sofia Park moving closer to commercial operation, the United Kingdom is taking a step forward in its goal of decarbonization and energy security.
