DeltaStream, the first full-scale tidal-energy generator in Wales, was unveiled at Pembroke Port earlier this month.

The patented 150-tonne device — developed by Cardiff-based Tidal Energy Ltd — will be installed in Ramsey Sound.

Named Ysbryd y Mor (Spirit of the Sea), it is part of a multi-million-pound investment in renewable energy, with the Welsh Assembly government pledging nearly £8 million of EU capital alongside ‘match funding’ from majority shareholder Eco2 Ltd.

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, plus the supply chain that now exists as a consequence of its development, marks the birth of the tidal-energy industry in Wales.”

First Minister Carwyn Jones said: “This is a landmark project for Wales, which will not only help us to meet our sustainable-energy ambitions but also provide significant opportunities for local people and businesses.”
