Working like an underwater windmill, the turbine’s two rotors are propelled by some of the world’s fastest tidal flows that stream in and out of the Lough at speeds of up to 8 knots.
It is moored to the sea floor 400 metres from the shore and will work for about 20 hours each day. No energy is generated during tide changes as tidal speed drops to below 2 knots.
