From the disclosure period beginning 1 April 2023 and onwards, GoOs are no longer recognised for use in GB FMD, FIT annual levelisation, or CfD. We also expect market participants to be able to meet proof of supply to GB requirements. 

This historic guidance details how suppliers provided information to Ofgem when presenting Guarantees of Origin (GoOs) for use in Great Britain (GB) Fuel Mix Disclosure (FMD) and Feed-in Tariff (FIT) annual levelisation. It also provided the basis upon which we advised the Low Carbon Contracts Company (LCCC) in its determinations of Green Excluded Electricity (GEE) under Contracts for Difference (CFD). 

The RE Compliance team, which is part of the Renewable Electricity Directorate of Ofgem, administered the EU GoOs recognition process for FMD.
