DeltaStream demonstration device

Cardiff-based tidal stream technology company Tidal Energy has introduced its full-scale tidal energy generator, DeltaStream, designed to identify the potential for renewable energy.

Scheduled to be deployed in Ramsey Sound, Pembrokeshire, the 400kW DeltaStream is considered as the world’s first demonstration device capable of generating green, sustainable and predictable tidal power.

The project has been supported by £8m of European Union funding, matched by majority shareholder Eco2.

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, TEL 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 the Welsh Government’s March 2014 plan for its Low Carbon Transition Strategy in marine renewable generation.

Wales First Minister Carwyn Jones said: "I’m delighted that Wales’ first full-scale tidal stream energy generator has been supported with almost £8m from the European Regional Development Fund.

"This is a landmark project for Wales, which will not only help us to meet our sustainable energy ambitions, but will also provide significant opportunities for local people and businesses."
