Generation and development


SSE is maintaining and investing in a diverse and sustainable portfolio of thermal and renewable generation plant. In moving towards a lower carbon generation mix, SSE will, by the end of the decade, transition its generation assets from a portfolio weighted towards gas and coal, towards one more weighted towards gas and renewables.

The practical application of this principle means that SSE currently owns or has an ownership interest in, around 10,643MW of capacity, which comprised at 31 March 2017:

  • 5,305MW of gas-and oil-fired capacity (GB and Ire);
  • 1,995MW of coal-fired capacity (with biomass co-firing capability); and
  • 3,272MW of renewable capacity GB and Ire (including hydro, pumped storage, onshore wind and offshore wind).

We publish information about power plant outages to provide greater market transparency. This is in line with the expected requirements of the new EU Regulation on Wholesale Eneregy Market Integrity and Transparency (REMIT).
