Low velocity tidal power project wins consent

A low-velocity tidal power project in Wales is a step closer to realization this week after receiving consent to install a demonstration device.

In the first phase of developer Minesto’s Holyhead Deep project, located 6.5 km off the coast of Anglesey, a 0.5 MW device is planned to be installed and commissioned this year. The installation will include the company’s ‘Deep Green’ tidal power unit, which it says can produce power from slow currents, plus a seabed foundation and a surface moored buoy. à‚ 

The project is planned to eventually feature a 10 MW array with 20 units. à‚ 

Conditions at Holyhead Deep include low-flow tidal velocities of 1.5 to 2 metres per second at a depth of 80 to 100 metres.

Engineering consultancy Xodus has now delivered the environmental impact assessment for the project, on the basis of which Natural Resources Wales has confirmed consent.

Xodus said it is also supporting Minesto’s research into the potential development of an 80 MW site which would include up to 160 units.
