Scottish & Southern Energy (SSE) plc has its origins in these two public sector electricity supply authorities, with both organisations privatised in the early 1990s with the deregulation of energy. They merged in 1998, creating one of the largest energy businesses in Great Britain with millions of domestic energy customers alongside operating the electricity networks across both regions.

In 2008, SSE acquired Airtricity, an Irish wind farm business, doubling renewables capacity to become the largest operator in the UK and Ireland.

Today SSE remains the UK’s largest generator of renewable energy, in keeping with our predecessors historic aim to provide safe and reliable electricity for all.

In 2020 we sold our GB electricity supply business to Ovo Energy, to focus on our core businesses of electricity networks and renewables, with complementary interests supporting the transition to a net zero world.
