New tidar power project for Scotland

Massive new tidal turbines could be operational at three undersea sites around Scotland by 2011, according to a report in The Times. ScottishPower Renewables has identified the Pentland Firth, the Sound of Islay, and the North Antrim coast off Northern Ireland as the most suitable sites for the underwater turbines. Each location will have between five and 20 1MW machines which could lead to a combined output of 60MW - enough to meet the energy needs of 40,000 homes.

Tidal turbines are described as similar to wind turbines but with much shorter blades which turn more slowly. They are anchored to the sea bed and aligned to the tidal flow. The UK has almost a 10 per cent share of the global tidal power resource, representing 13bn kilowatt-hours. More than 80 per cent of the potential is located in Scottish waters.
