    SSE Plc history, company profile (overview) and history video

       SSE Plc is a multinational energy company headquartered in Perth, Scotland, the United Kingdom.

       The company develops, owns and operates low-carbon infrastructure, including onshore and offshore wind, hydropower, electricity transmission and distribution grids, and efficient gas-fired generation, alongside providing energy products and services for businesses.

       It has interests across Great Britain and Northern Ireland, the Republic of Ireland, Japan, Spain, Portugal, Denmark, and Poland.


       SSE has its origins in two public sector electricity supply authorities, The North of Scotland Hydro-Electric Board and the Southern Electricity Board.

       The North of Scotland Hydro-Electric Board was formed with the Hydro Electric Development Act in 1943, delivering electricity to the Highlands for the first time.

       The former Southern Electricity Board was created in 1948 to distribute and supply electricity in southern England.

       Both organizations were privatized in the early 1990s with the deregulation of energy. The North of Scotland Hydro-Electric Board became Scottish Hydro-Electric, while the Southern Electricity Board became Southern Electric.

       In 1998, Scottish Hydro-Electric and Southern Electric merged to create Scottish and Southern Energy, which became one of the largest energy businesses in Great Britain.

       In 2000, Scottish and Southern Energy acquired the SWALEC energy supply business.

       In 2008, SSE acquired Airtricity, an Irish wind farm business.

       In 2010, Scottish and Southern Energy Plc was renamed SSE Plc.

       With more than 12,000 employees, SSE plc (formerly Scottish and Southern Energy plc) is considered one of the largest generators of renewable electricity and one of the largest electricity network companies in the United Kingdom. According to Forbes, it is considered one of the Largest Public Companies in the World.
