The Renewables Obligation (RO) is the main support mechanism for renewable electricity projects in the UK, and is available to any generator over 50kW in size. Smaller scale generation is mainly supported through the Feed-In Tariff scheme (FITs).   

The RO came into effect in 2002 in England and Wales and in Scotland and in 2005 in Northern Ireland. It places an obligation on UK electricity suppliers to source an increasing proportion of electricity they supply to customers from renewable sources.    

Renewables Obligation Certificates (ROCs) are green certificates issued by OFGEM to operators of accredited renewable generating stations for the eligible renewable electricity they generate. Operators can then trade the ROCs with other parties, with the ROCs ultimately being used by suppliers to demonstrate that they have met their obligation.

How to make an application   

In order to make an application for accreditation under the RO as a renewable generator, applicants will first need to register for an account on the Renewables and CHP Register. Once this account has been activated, users can access it and apply for accreditation, make the relevant declarations, submit monthly output data and receive/transfer their ROCs. More information about this process can be found here.
