A new project that will harness Welsh tidal energy has been approved by Energy Secretary Chris Huhne.

The 1.2MW ‘Deltastream’ device has the potential to power up to 1,000 homes, and will provide electricity to the local network during a 12 month test period.

Mr Huhne said: “I wish Tidal Energy the best of luck with testing their Deltastream device off Wales. This is exactly the kind of innovative and exciting project I want to see more of.”

Tidal Energy Limited’s Deltastream device will be powered by tidal energy in Ramsey Sound off Pembrokeshire.
