Renewables Obligation Certificate
(Redirected from ROC)
A Renewables Obligation Certificate (ROC) is produced per unit of electricity generated from eligible renewable sources and generated or purchased by an energy supplier to demonstrate it has sourced a set percentage of their electricity from renewables. Introduced by the Renewables Obligation Order 2002 (which page covers more detail) – the subsidy is now replaced by Contract for Difference (CFD) for larger projects and Feed in Tariffs (FITs) for smaller schemes. Ofgem administer both the RO and CFD schemes with Government Department for Business, Energy and Industrial Strategy developing the schemes policy and rules.
