Key points of interest from the Renewables Obligation Annual Report for the year ending 31 March 2017:

Renewables Obligation Certificates (ROCs) issued and renewable generation

  • We issued 86.2 million ROCs in 2016-17 compared to 90.4 million ROCs in 2015-16. This was lower than the total UK supplier obligation of 100.7 million ROCs.
  • ROCs were issued based on 65.2TWh of renewable generation, equivalent to 22.2% of the total electricity supplied in the UK. When combined with the 7.5TWh generated by Feed-in-Tariff (FIT) installations, this figure rises to 24.8%.
  • 28.3 million tonnes of carbon dioxide equivalent (CO2e) emissions were avoided through renewable generation under the scheme.

Generating stations accredited

  • We accredited 4,531 generating stations in 2016-17, a substantial reduction from the 6,724 generating stations accredited in 2015-16.
  • The vast majority (3,505) of the stations accredited were microgenerators in NI.
  • However, the aggregate capacity of the stations we accredited during 2016-17 was 2,601MW, which represents a 27% increase on the 2,033MW reported in 2015-16.

Compliance by licensed electricity suppliers and scheme value

  • 90.21 million ROCs were presented by supplier, which was 89.5% of the total obligation in comparison to 99.9% of the obligation in 2015-16 
  • This resulted in the highest buy-out fund recorded since the RO began, totalling over £464.3 million.
  • Each ROC was worth £49.87, leading to a scheme value of £4.5 billion.
