The power supply contract is about £600 million in total over a possible 4 year term. The electricity generated from renewable energy sources will power large Scottish public sector buildings, and starting in October 2009, electricity will be available for use in schools, universities, hospitals and prisons, along with other large government and local authority buildings. ScottishPower sees this contract as a great opportunity to bring clean energy to Scottish consumers. With Scotland having some of the best renewable energy sources in Europe, it was only right that the Scottish Government should lead the way in "supporting a greener future".

The contract will allow ScottishPower to harness renewable energy from three out of four lots available in Procurement Scotland's tendering process, which started back in September 2008. As part of the awarded contract, the company will also have rights to power all of Scotland's street lighting requirements. ScottishPower's is completing the Whitelee Windfarm, near Glasgow, the largest in Europe, which will significantly contribute to the Scottish Government contracts.
