The tidal energy generator is scheduled to be deployed in Ramsey Sound, Pembrokeshire.

Supported by £8m of European Union funding, matched by majority shareholder Eco2, the 400kW DeltaStream is considered to be the world’s first demonstration devices capable of generating green, sustainable and predictable tidal power.

Tidal Energy managing director Martin Murphy said "We have achieved a number of firsts with this project, including those relating to the environmental consents, the grid connection and the installation process – where the turbine and foundation are installed together.

"The imminent launch of DeltaStream, and the supply chain that now exists as a consequence of its development, marks the birth of the tidal industry in Wales."

Upon completion of testing, Tidal Energy and renewable energy firm Eco2 will join forces to deploy up to nine DeltaStream devices off St Davids Head in Pembrokeshire.

The installations will form a 10MW DeltaStream commercial array, generating enough energy for about 10,000 homes.
Eco2 chief executive Dr David Williams said: "The St Davids Head project will serve to further prove the commercial viability of DeltaStream and marine renewable energy as a whole.

"The device has excellent export potential for deployment in high energy tidal sites around the world, and we intend to harness this tidal potential."

The DeltaStream project is the first step in Welsh Government’s March 2014 Plan for its Low Carbon Transition Strategy in marine renewable generation.
