The first full-scale tidal energy generator to be deployed in Welsh waters has been unveiled by the country’s First Minister.
The DeltaStream device, developed by tidal stream technology company Tidal Energy (TEL), will be installed in Ramsey Sound, Pembrokeshire and will be one the world’s first grid-connected demonstration devices to generate sustainable tidal power.
The 400kW demonstration device, which weighs 150 tonnes and with a frame 16 metres long by 20 metres high, combines a freestanding triangular base design with a hydraulics system, which ensures the turbine freely turns to capture the best tidal flow and maximise power generation.
“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,” said Martin Murphy, managing director of Tidal Energy.
“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.
“We remain committed to leading the expansion of this industry and to the creation of green jobs by building on the wealth of expertise present in the UK and the country’s plentiful resources.”
The first private marine project to be fully completed in Wales received £8million from the EU, matched by funding by Welsh renewable energy company, Eco2.
Following a 12 month testing period, the partnership between TEL and Eco2 will install up to nine DeltaStream devices off St Davids Head in Pembrokeshire to form a 10MW array which will generate enough power for around 10,000 homes.
“I’m delighted that Wales’ first full scale tidal stream energy generator has been supported with almost £8million from the European Regional Development Fund,” said the First Minister of Wales Carwyn Jones.
“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.”
