Tidal Energy Wales

Cardiff-based Company Tidal Energy has been given permission to install its 1.2MW DeltaStream tidal energy array in Ramsey Sound off Pembrokeshire.
The installation will provide electricity to the local distribution network during its 12-month test period, with the potential to power up to 1,000 homes.
DeltaStream rests on the seabed without the need for a positive anchoring system, generating electricity from three separate horizontal-axis turbines mounted on a common frame.
The use of three turbines on a single, 30m-wide, triangular frame produces a low centre of gravity that stops the device overturning and sliding.
