The Renewables Obligation Order 2006 will replace the Renewables Obligation Order 2005 with effect from 1 April 2006. The provisions of the 2006 Order, which are broadly similar to those of the 2005 Order, require all licensed electricity suppliers to provide evidence (through the presentation of Renewables Obligation Certificates, also known as ROCs, or their Scottish or Northern Irish equivalents) that a specified and growing proportion of the electricity they supply (currently 5.5%) has been generated from renewable sources.
The 2006 Order introduces provisions relating to the calculation of eligibility for ROCs of electricity generated by combined heat and power generating stations fuelled wholly or partly by waste. It also introduces a preliminary accreditation procedure for generating stations that have not yet been commissioned, under which they can be accredited as being capable of generating electricity from renewable sources.
