[RenewableEnergyAccess.com] Key stakeholders in the United Kingdom energy industries supplied the Department of Trade and Industry with over 90 comments on the Renewables Obligation draft terms since August of this year. There was strong support for a limited review to improve the effectiveness of the obligation, which ensures all electricity suppliers produce a specified and increasing amount of energy from renewable sources, while avoiding changes to the key operating principles. Stakeholders said they would like to see a review of the effectiveness of the obligation since it began in 2002, of all aspects of the working arrangements, of levels of the obligation beyond 2015, of the potential impact of the European Union Emissions Trading Scheme on carbon and the competitiveness of renewable technologies, and of the availability of energy from mixed wastes. The Renewables Obligation requires all licensed electricity suppliers in England and Wales to supply a specified and growing proportion of their electricity sales from a choice of eligible renewable sources. Individual suppliers are responsible for demonstrating their compliance to the energy regulator Ofgem through a system of Renewables Obligation Certificates (ROCs). The obligation is the key policy mechanism by which the Government is encouraging the growth necessary to reach the UK’s renewable energy target of 10 percent of electricity from renewable sources by 2010.
