Prysmian to supply export cables for Welsh tidal energy array

(offshore-energy.biz) The Italy-based global power cable manufacturer Prysmian will supply subsea export cables for the HydroWing tidal energy array, led by UK-based Inyanga Marine Energy Group at the Morlais site off Anglesey, Wales.

Scheduled for deployment in early 2026, the HydroWing array aims to deliver 20 MW of predictable marine energy to the UK grid using seabed-mounted underwater wings that rotate with tidal currents to generate electricity. 

According to Prysmian, the system mirrors wind turbines but harnesses ocean currents instead, leveraging a predictable tidal resource driven by lunar cycles.

The Morlais site is one of Europe’s largest consented zones for tidal stream energy. The Welsh Government has supported its development with £8 million (around $10 million) in equity investment, alongside a £2 million investment in Inyanga.

Prysmian’s role is said to involve manufacturing and delivering export cables capable of operating in harsh marine environments. The cables will transfer electricity from the subsea turbines to shore.
