Renewables Obligation (RO) Annual Report 2019-20

Reports, plans and updates

Key points of interest from the Renewables Obligation Annual Report for the year ending 31 March 2020:

Compliance by licensed electricity suppliers and scheme value

  • 115.94 million Renewables Obligation Certificates (ROCs) were presented by suppliers in the 2019-20 obligation year.[1] This was 89.1% of the total obligation of 130.18 million ROCs, and a slightly higher proportion in comparison to the 84.3% presented for the 2018-19 obligation year.
  • This resulted in a buy-out and late payment fund totalling over £654.6 million.
  • Each ROC was worth £54.43, resulting in a scheme value of £6.3 billion.


  • In 2019-20, 13 suppliers did not meet their obligation resulting in a shortfall of £33.1m in the buy-out/late payment funds. This shortfall triggered mutualisation for the third successive year.

Renewables Obligation Certificates (ROCs) issued and renewable generation

  • We issued 114.7 million ROCs in 2019-20, the highest number issued in the scheme’s history.
  • ROCs were issued based on 84.9 TWh of renewable generation. This was equivalent to 31% of the UK electricity supply market.
  • Total generation when including output on the Feed-in Tariffs (FIT) and Contracts for Difference (CfD) schemes rises to 112.8 TWh, equivalent to 41.2% of UK supply .

Generating stations accredited

  • From the start of the scheme in 2002, we have accredited 26,582 generating stations with a total capacity of 35.4GW.
