These fiscal schemes areoutlined below. It should be noted that the schemes aresubject to ongoing review, which has informed a degree ofuncertainty and inertia amongst developers.3.2.1 Renewable Obligation Certificates for large scale renewable electricityThe Renewable Obligation (RO) is presently the UK’smechanism for ensuring that large scale renewable generationprojects have grid parity with non-renewable generation.Through the RO, developers receive a subsidy in the form ofRenewable Obligation Certificates (ROCs), which areallocated for each megawatt hour of electricity generated. Thenumber of ROCs awarded varies between technologies – for Figure 1: Renewable electricity technology capacities –example in 2012, 2 ROCs / MW were awarded for offshore comparison between 2008 and projected to 2020 [6]wind farms and 1 ROC / MW for onshore.
