More than 5,000 homes could be powered by tidal energy with a new development off the west coast of Scotland.
Scottish Power Renewables is building a £40 million tidal array which it says will be the world’s largest tidal stream energy development.
The 10 megawatt facility will harness the power of tides in the Sound of Islay for more than double the number of homes on the island, while developing emerging tidal energy technology.
Scottish cabinet secretary for finance and sustainable growth John Swinney said the development will cement the country’s position as a global leader in marine energy.
"With around a quarter of Europe's potential tidal energy resource and a tenth of the wave capacity, Scotland's seas have unrivalled potential to generate green energy, create new, low carbon jobs, and bring billions of pounds of investment to Scotland,” he said.
"This development does just that and will be a milestone in the global development of tidal energy."
Mr Swinney added that the green development would also maximise social and economic opportunities for residents of Islay and Jura, with new jobs created by the construction phase and Scottish businesses set to benefit from £4 million worth of contracts in making turbines.
"With the highest support levels in the UK for wave and tidal energy, our £10 million Saltire Prize - Scotland's energy challenge to the world to inspire innovation in marine energy - and our low carbon investment project, Scotland is one of the most attractive markets in the world for investment in marine renewables," he said.
