As part of the impact assessment to the Renewables Obligation Banding Review the Department assessed of the amount of woody biomass, including domestic and imported, that is likely to be used for electricity generation up to 2017. This year we have aggregated data provided to Ofgem under the Renewables Obligation biomass sustainability reporting requirements. We also asked all large scale electricity generators using biomass to provide the Department with an estimate of the amount of UK-sourced wood they expect to source over the coming five years. The results of these two analyses have now been published: https://www.gov.uk/government/uploads/system/uploads/attachment_data/file/246006/UK_wood_and_biomass.pdf These data support the Department's initial estimates of the amount of UK biomass that is expected to be used for electricity generation up to 2017 (of between 2.5 and 3.5 million oven dried tonnes (modt)). Use of UK biomass for electricity has remained stable over the 2009-12 period at between 2.3 and 2.5 modt (of which between 1.3 and 1.6 modt was wood).
