Wales’ first full-scale tidal energy generator has been unveiled at Pembroke Port.
The DeltaStream device developed by Tidal Energy Ltd (TEL) will now be installed in Ramsey Sound, Pembrokeshire, making it one of the world’s first grid-connected demonstration devices to generate tidal power.
DeltaStream combines a freestanding triangular base design with an advanced hydraulics system, which ensures the turbine freely turns to capture the best tidal flow and maximise power generation. Gravitational pull anchors the device in place, eliminating the need for drilling into the seabed.
Tidal Energy Ltd’s DeltaStream 400kW demonstration device, which weighs 150 tonnes and with a frame 16m long by 20m high, also includes a number of design features to minimise any potential impact on the surrounding environment.
Consequently, DeltaStream is the first project to receive precautionary ‘deploy and monitor’ environmental consent in a designated Marine Special Area of Conservation.
EU funds worth £8m delivered through the Welsh Government have been invested in the project, with match funding from majority shareholder, Welsh renewable energy company, Eco2 Ltd.
Following a 12 month testing period, TEL and Eco2 will install up to nine DeltaStream devices off St Davids Head in Pembrokeshire. These installations will form a 10MW DeltaStream commercial array.
