HOLYHEAD DEEP LOW VELOCITY TIDAL ENERGY PROJECT

April 24, 2017

Leading tidal energy developer Minesto has taken yet another important step towards commercialisation of its unique Deep Green technology in Welsh tidal streams, as the company has received marine license for a 0.5MW installation in Holyhead Deep. Consenting authority Natural Resources Wales has approved a marine licence application by Minesto for the installation and operation of a 0.5MW Deep Green power plant in Holyhead Deep off the coast of Anglesey. Leading up to the approved application an in-depth Environmental Impact Assessment (EIA) has been carried out. The EIA considered the potential impacts acts on fisheries, marine mammals, sea birds, marine archaeology and cultural heritage as well as shipping and navigation, which were concluded to be not significant.
The now consented installation in Holyhead Deep is planned for this year and it will include a single Deep Green device, seabed foundation and a buoy moored at surface. This first commercial-scale installation of Deep Green will demonstrate and prove the unique tidal energy technology ahead of plans to expand Holyhead Deep into Minesto’s first tidal energy array.
Functionality and power production of the Deep Green technology have been verified in ocean testing of scale prototypes. To date, five prototypes have been built and tested, and electricity was first produced in 2009. The first commercial-scale project of the Deep Green technology is well underway. (Source: Minesto)
