A tidal energy project west of Anglesey has been granted consent by Natural Resources Wales.
Minesto aims to demonstrate the 0.5MW Deep Green device ahead of plans to install a 10MW array at the site.
It will be located in the southern corner of Holyhead Deep, 6.5km off the coast of Anglesey.
The first phase includes a single device, seabed foundation and a surfaced moored buoy, with installation planned this year.
Ylva Sörqvist Hultgren, Site Development Manager at Minesto said: “This first step of implementing our unique technology in commercial scale is obviously an important one and it is therefore satisfying to have reached this milestone.”
The company is working with Xodus Group on a scoping report for the potential development of an 80MW site, which would include up to 160 devices installed in phases in Holyhead Deep.
