Operating a diverse range of renewable generation

SSE had 2,975MW of Renewable capacity by the end of September 2016, including its share of joint ventures, with 2,731MW of this in GB. The GB portfolio comprised (net):

  • 1,150MW conventional hydro;
  • 900MW onshore wind;
  • 344MW offshore wind
  • 300MW pumped storage
  • 37MW dedicated biomass.

Output from around 1,750MW of SSE’s renewable portfolio in GB qualifies for Renewable Obligation Certificates (ROCs). In the 12 months to 31 march 2016, total electricity output from SSE’s renewable resources in GB and Ire was 9,695 GWh (including pumped storage).

Output of electricity from renewable sources decreased in the first half of 2016/17, compared to the same period in 2015/16 (3,026GWh compared to 3,805GWh). The primary driver for this differential was the weather; put simply there was lower rainfall and less windy conditions in the first half of 2016/17 across Great Britain than in the same period last year. Overall renewable capacity also reduced slightly, from 3,093MW to 2,975MW, following the sale of 49.9% of Clyde wind farm in March 2016. Availability of the renewable portfolio remained high throughout the period.
