Energy suppliers

Renewable Energy Guarantees of Origin certificates (REGOs) allow electricity suppliers to prove to their final customers that a given share of energy was produced from renewable sources.

Suppliers are required to hold REGOs in their accounts on the Renewables and Combined Heat and Power (CHP) Register by midday on 1 July following the previous disclosure period (1 April to 31 March) as part of the evidence for Fuel Mix Disclosure (FMD).

Requests to recognise EU Guarantees of Origin (GoOs) must also be agreed by this date.

Further information is available in the creating an account section of the Renewables and CHP Register guide, and on the transfer of REGOs in the guidance for generators.
