SSE

SSE plc is a publicly listed British energy utility headquartered in Perth, Scotland, operating across the United Kingdom and Ireland. Formed in 1998 from the merger of Scottish Hydro-Electric and Southern Electric, it has evolved from a regional electricity supplier into an integrated infrastructure owner and generator focused on low‑carbon power and networks. The group develops, owns and operates electricity generation from renewable and thermal sources, high‑voltage transmission and distribution networks, gas storage, and related energy market and service activities. In the 2025 financial year SSE reported revenue of £10.1 billion, operating income of £2.35 billion and employed 14,880 people. Operationally, SSE is structured around specialist business units. SSE Renewables develops and operates onshore and offshore wind farms and hydroelectric schemes in the UK and Ireland. SSE Thermal runs a fleet of flexible gas‑fired and multifuel power stations and is advancing projects in carbon capture, hydrogen power and long‑duration storage. SSEN Transmission and SSEN Distribution own and operate the electricity transmission network in the north of Scotland and distribution networks in the north of Scotland and central southern England, providing grid connections for customers and new generation. SSE Airtricity supplies energy in the all‑island Ireland market, while SSE Energy Solutions and SSE Energy Markets provide business energy supply, distributed energy, smart building and portfolio management services. SSE has progressively exited domestic GB retail supply and non‑core gas exploration to concentrate capital on regulated networks and renewables. It is now the largest renewable electricity generator in the UK and Ireland and is executing multi‑year, multi‑billion‑pound investment programmes, including a record £2.9 billion invested in energy infrastructure in 2024/25, to expand offshore wind, upgrade transmission capacity, and support the transition to net zero.
