Draft PPS18: Renewable Energy
Annex 1 Introduction: Implications of the Renewables Obligation
D7. The Renewables Obligation Order (Northern Ireland) 2006 states that only electricity derived from ‘biomass’ will be eligible for Renewable Obligation Certificates (ROCs). ‘Biomass’ is defined here as a fuel of which at least 98% of the energy content is derived from plant or animal matter or substances derived directly or indirectly there from (whether or not such matter or substances are waste) and includes agricultural, forestry or wood wastes or residues, sewage and energy crops.
D8. A generating station which is fired wholly or partly from waste is excluded from receiving ROCs unless:
- the only fuel is biomass in accordance with the above definition; or
- advanced conversion technologies (e.g. pyrolysis and gasification) are used to produce a fuel gas, in which case ROCs can be claimed for the biomass fraction of the fuel. This is an incentive for the development of new technology which is inherently cleaner and can be deployed on a smaller scale.
D9. In accordance with this definition, conventional waste incinerators firing MSW will not be able to claim ROCs for the electricity they generate. Only those installations eligible for ROCs are counted as renewable energy generation in the context of this document. Any firing of non-biomass waste will result in the plant being subjected to far more stringent controls, which needs to be borne in mind when considering MSW as a fuel.
