About Scottish Power
Scottish Power is one of the UK's major domestic energy suppliers, serving approximately 2.7 million households. The company traces its origins to the privatisation of the Scottish electricity industry in 1991 when it was established as a publicly listed company to take over the former South of Scotland Electricity Board.
Scottish Power was acquired by Spanish energy company Iberdrola in 2006. Iberdrola is one of the largest utility companies in the world with operations across Europe, North America, and South America. The Qatar Investment Authority became a significant shareholder in Iberdrola from 2023. Scottish Power operates under the Iberdrola group but maintains its own brand and management structure in the UK.
Scottish Power is among the most active developers of onshore and offshore wind energy in the UK through its generation division, which operates separately from its retail supply business.
