is likely to be an important part of a massive £40 million tidal energy project announced by the Scottish Government this week.
A ten megawatt (MW) power array will be developed in the Sound of Islay, on Scotland's west coast.
The first project of its kind in the world, the ten turbines - each generating 1MW - will create enough renewable electricity to power 5,000 houses, double the number on Islay.
Engineers chose The Sound of Islay - a channel of water that separates the islands of Jura and Islay - because of its key benefits.
It has strong tidal flows, shelter from storms and waves and grid capacity.
ScottishPower Renewables will oversee the development, which will begin in 2012.
Scottish finance secretary John Swinney said: "[The] ScottishPower Renewables array will work in harmony with the environment and use the power of the tides in the Sound of Islay to generate enough green energy to power double the number of homes on Islay.
"There is simply nothing like it consented anywhere else in the world."
