The Government does not hold this information. Electricity generators only receive subsidies for biomass where they comply with the UK’s stringent sustainability criteria. The criteria requires that electricity generation from biomass does not exceed a set GHG threshold and produces life-cycle GHG emission savings (including transport and supply chain emissions) compared to fossil fuels. Suppliers/generators must demonstrate to the regulator (Ofgem) that they meet the criteria. Their evidence is independently audited.
