Ofgem administer the issuing of ROCs to renewable generators. They do not keep data on the number of generators who are households; however 57 of the 975 accredited generators were small generators below 50KW, and accredited to individuals rather than businesses. These 57 small generators claimed 952 ROCs in the 2005-06 period.
We do not keep data on average ROC prices for generators; however the nominal value of a ROC to suppliers for 2005-06 was £42.54.
Changes we have introduced in the Renewables Obligation Order 2006 (Amendment) Order 2007—currently before Parliament—will remove the requirement for sale and buyback agreements and allow agents to act for small generators, including householders. It is expected these changes will make it easier for householders to claim ROCs. Ofgem are expecting a consequent rise in the number of applications from small generators.
