Audits of Renewables Obligation (RO), Renewable Electricity Guarantees of Origin (REGO) and Feed-in Tariffs (FIT) Generating Stations 2022/23

As the administrator of the Renewables Obligation (RO), Renewable Electricity Guarantees of Origin (REGO) and Feed-in Tariffs (FIT) schemes, we carry out an annual audit programme of generating stations. The purpose of our audits is to confirm that the information provided during accreditation was correct and to ensure ROC/REGO/FIT claims are accurate. Our audit programmes detect and deter non-compliance, misreporting and fraud in the schemes. Similarly to 2021/22, we are running both a targeted and a statistical audit programme during 2022/23 under the RO. We are also running a targeted audit programme during 2022/23 under the FIT scheme.

Launch of the statistical audit programme for Renewable Obligation (RO) Generating Stations 2022/23

This is the third year of our statistical audit programme under the RO scheme and will be carried out alongside our targeted audit programme. Unlike in previous years, this years RO statistical audit programme will start in October 2022. Our RO statistical audit programme will run for 18 months, instead of the usual 12 months. This means that the third year of the RO statistical audit programme will continue into 2023/24. These changes to our audit timeframes will allow our audit team to implement improvements including streamlining our processes and an improved generator experience. The targeted RO and FIT audit programmes for 2022/23 are unaffected by this change and will continue to run for 12 months which started in April 2022.

Have there been any changes to the audit process for 2022/23?

Previously our audit team were responsible for resolving all findings raised from an audit. Going forward, once the audits findings have been shared with the generator, any potential financial non-compliance findings that have been identified will be referred to our Renewable Electricity (RE) participant compliance team to investigate. The RE participant compliance team will then determine whether a compliance case is required to be opened.

As a generator, what can I do to support Ofgem’s review?

Currently, our RE participant compliance team are processing a high volume of cases. We’re keen to work closely with generators and updates will be shared when they become available. To minimise the review time, please respond to our information requests by the requested deadline and the responses should include supporting evidence, when requested. If you have any questions, please contact
