Prysmian Powers the Future of Clean Energy with Inyanga’s Tidal Project in Wales

Harnessing the ocean’s strength to fuel a greener tomorrow

Prysmian is joining forces with Inyanga Marine Energy Group to bring a groundbreaking tidal energy project to life off the coast of Wales. The HydroWing project is set to become one of Europe’s most advanced tidal energy ventures, aiming to generate 20 megawatts of clean, renewable electricity—enough to power thousands of homes across the UK and it also strengthen the UK's leadership in renewable marine technologies.

This project represents a major leap forward in the use of ocean currents to produce sustainable energy and is also a boost for the local economy in Wales through green jobs and infrastructure.

Scheduled for deployment in early 2026, the HydroWing array will be installed at the Morlais tidal energy site, located 3,5 km off the coast of Anglesey. The HydroWing system uses underwater wings mounted on the seabed that rotate with the movement of tidal currents. This motion drives turbines that generate electricity—similar to how wind turbines work, but underwater.

Hydrowing project is the demonstration of the scalability of marine energy solutions, that can be also used in other coastal regions.

Prysmian manufactures and supplies the export cables that will carry the electricity from the underwater turbines back to shore. These cables are designed to withstand the marine environment, including strong currents and extreme weather conditions.

“We are honored to contribute to a project that not only showcases cutting-edge marine engineering but also aligns with our deep commitment to driving the energy transition forward,” said Massimiliano Tommasini, Vice President of Offshore Specialties at Prysmian. 

This collaboration reflects Prysmian’s strategy to lead the shift toward cleaner energy. The company is investing heavily in research and development, sustainable manufacturing, and circular economy practices. Its submarine cables are increasingly made with recycled materials and produced using low-impact processes—all part of its goal to reach net-zero emissions by 2035.

The Welsh Government has invested £2 million in Inyanga Marine Energy Group and continues to support tidal energy more broadly, including an £8 million equity investment in Morlais. Tidal energy is a promising renewable source because it’s predictable and consistent—unlike wind or solar, tides follow a reliable schedule. Projects like HydroWing not only help reduce carbon emissions but also demonstrate how innovation and collaboration can tackle climate change.

By supporting this project, Prysmian is helping to shape a more sustainable and greener future.

With over 100 years of history in the UK, Prysmian has an established headquarter in Eastleigh, Southampton and 3 further manufacturing sites in Eastleigh, Wrexham and Aberdare to help better serve our UK and export markets. Besides our factories in the UK, Prysmian can rely also on several service offices and distribution centres, advanced laboratories and testing facilities and a marine base in Middlesborough, where we have also a storage area of marine and subsea equipment, maintenance facility for the marine equipment, large docking pier, dedicated carousels for submarine cable long term storage.

Prysmian has made significant contributions to the UK’s infrastructure through various projects: submarine interconnections such as IFA2, North Sea Link, Viking Link, the world’s longest land and submarine interconnector and land interconnector such as Eleclink and offshore wind farms like Hornsea 2, Sofia and Kinkardine, Prysmian’s first cable project for a floating offshore wind farm.
