ROCs
Renewable Obligation Certificates (ROCs) are certificates given to registered generators of renewable electricity produced and sold within the UK. However these will be phased out as the feed-in tariff starts in April 2010.
Currently you will be entitled to one certificate for each megawatt hour (or 1,000 kilowatt hours kWh) of electricity you produce.
Some tariffs include a price for ROCs whereby the energy supplier acts as the ROC agent, claiming ROCs from Ofgem on behalf of the customer. However, there are other tariffs where the customer retains the ROC entitlement and must claim these themselves.
For ROCs to be able to be claimed you must have a Total Generation Meter installed, which is included in our system. Information on which tariffs include a payment for ROCs can be viewed by looking at the tariff details on the Energy Saving Trust's buy-back tariff search tool.
Some suppliers include the payment for ROCs within the tariff, this means the ROCs are claimed by the energy company on the customers' behalf. If the tariff does not include payment for ROCs then the customer can claim for them separately.
