The Renewables Obligation Certificates (ROC) are designed to incentivise the generation of electricity from eligible renewable sources in the United Kingdom. It was introduced in England and Wales and in a different form (the Renewables Obligation (Scotland)) in Scotland in April 2002 and in Northern Ireland in April 2005.

The ROC Scheme places an obligation on licensed electricity suppliers (NIE, Scottish Power) source an increasing proportion of electricity from renewable sources. In 2006/07 it is 6.7% (2.6% in Northern Ireland). This figure was initially set at 3% for the period 2002/03 and under current political commitments will rise to 10.4% by the period 2011-12, then by 1% annually for the five years following.

From the 1st April 2011, Wind Turbines up to and including 50kW must fully UK MCS Certified to qualify for NIROCs. Both the Gaia 133 and the Endurance E-3120 are fully complaint.

Currently in Northern Ireland, 4 ROC’s are issued for every 1000kwh (1MW) generated by a wind turbine up to 250kw. ROC’s can be traded on the open market, or sold back to your electric provider at a set price, you decide. It does not matter if you generate and use all of your electric, you will still be in line for a ROC payment. The ROC generation figure is taken as a reading, from the Ofgem approved ROC meter installed by Silverford.
