All EU member states must have a Guarantees of Origins (GoOs) scheme. In the UK, our version is called Renewable Energy Guarantees of Origin (REGO). Ofgem is required by legislation to recognise overseas GoOs if they are presented to us for the purposes of Fuel Mix Disclosure (FMD) and Feed-in Tariffs (FIT) Levelisation.
Please note: Ofgem’s administration of the REGO scheme and fuel mix disclosure is not affected by EU Exit. We will continue to issue REGOs and accept guarantees of origin (GoOs) from EU member states after EU Exit Day. REGOs issued in the UK will no longer be recognised by EU member states after exit day in a no deal scenario. Under the draft withdrawal agreement published by the UK government on 25 November 2018, there will be a transition period, during which UK REGOs will continue to be recognised by EU member states until 31 December 2020.
Use in Fuel Mix Disclosure and Feed-in Tariffs levelisation
GoOs label electricity from renewable sources to provide information to electricity customers on the source of their energy. They are used by suppliers for FMD compliance along with GB-issued REGOs to show how much renewable electricity they have supplied in the previous year.
GoOs are also used by suppliers to exempt themselves from some of their FIT costs via the FIT levelisation process.
How to get GoOs recognised by Ofgem
As Ofgem’s Renewables and CHP register is not compatible with overseas GoOs, they must be cancelled in another country’s register before being presented to us. In order to get them recognised, suppliers must read the documents provided and follow the specified processes. Suppliers must submit an audit report alongside their presented GoOs. The audit report must be written in the standard of ISAE 3000.
