Tidal power installed in Ramsey Sound
Welsh tidal stream technology company Tidal Energy has installed the country’s first tidal energy generator in Ramsey Sound, Pembrokeshire. The DeltaStream device will become one of the first grid-connected demonstration devices worldwide to generate green, sustainable and predictable tidal power.
Weighing 200 tonnes, with a frame 16 m long and height of 18 m, the 400 kW demonstration device has a gravity-based foundation which sits on the seabed under its own weight, without the need to drill or pile the structure into the seabed.
The company says that Ramsey Sound was chosen as the test-site because it is sheltered from prevailing wind and wave conditions, but has a good tidal climate with tidal streams reaching up to 3 m/s on spring tides. There is a good grid connection feeding electricity to St David's city and excellent port facilities nearby in Pembroke Port.
