About the REGO scheme
What is it?
The Renewable Energy Guarantees of Origin (REGO) scheme provides transparency to consumers about the proportion of electricity that suppliers source from renewable generation.
All EU Member States are required to have such a scheme.
The Government will ensure that Great Britain and Northern Ireland will continue to issue REGOs and accept Guarantees of Origin (GoOs) from EU member states from 1 January 2021 (i.e. once the implementation period has expired). This will allow electricity suppliers in the UK to continue to use REGOs and EU GoOs to comply with their fuel mix disclosure obligations. We also expect market participants to be able to meet proof of supply requirements in GB whatever the arrangements are following the transition period, including explicit (no-deal arrangements for Continental interconnectors) trading arrangements.
Government has indicated its intention to review this in 2021 so that, longer term, domestic recognition of Guarantees of Origin issued in EU countries will take place only on a reciprocal basis.
Ofgem is unable to provide any guarantees with regards to whether UK REGOs retired by suppliers for the purpose of export out of the UK will be accepted in the EU. As such we encourage suppliers to seek independent advice on this aspect.
What do we do?
We administer the scheme for generation in Great Britain on behalf of the Department for Business, Energy & Industrial Strategy (BEIS), and in Northern Ireland on behalf of the Northern Ireland Authority for Utility Regulation (NIAUR).
We regularly report to HM Revenue & Customs (HMRC) and BEIS, and are responsible for the annual Fuel Mix Disclosure (FMD) compliance deadline.
How does it work?
We issue one REGO certificate per megawatt hour (MWh) of eligible renewable output to generators of renewable electricity.
The purpose of the certificate is to prove to the final customer that a given share of energy was produced from renewable sources. As such, the primary use of REGOs in Great Britain and Northern Ireland is for Fuel Mix Disclosure. FMD requires licensed electricity suppliers to disclose to potential and existing customers the mix of fuels (coal, gas, nuclear, renewable and other) used to generate the electricity supplied.
Who can apply?
Renewable generators of any size in Great Britain and Northern Ireland can apply for the scheme.
Applications for accreditation under the scheme are made via the Renewables and CHP register. For generators to receive certificates, generation data must be submitted via the register. Once issued, the certificates can be transferred to other Renewables and CHP register account holders.
