SSE will contribute funds to the construction costs by buying up two million Carbon Emissions Reduction certificates over five years from 2008.
"Climate change is literally a global challenge and supporting the development of clean sources of energy anywhere in the world is a key means of addressing it," Ian Marchant, chief executive of SSE, said.
"We have deliberately acquired CERs which relate to a mature electricity generation technology which we have experience of operating, because we want to be sure that they are making a real difference.
"The large majority of our investment in reducing carbon emissions will continue to be in the UK but CERs are an effective means of supplementing it."
