Question to the Department for Business, Energy and Industrial Strategy:

To ask the Secretary of State for Business, Energy and Industrial Strategy, what estimate he has made of the cost to the public purse of subsidies provided to renewable technologies burning wood for fuel under the (a) Renewables Obligation Certificate, (b) Contract for Difference, (c) Feed in Tariff and (d) Domestic and Non-Domestic Renewable Heat Incentive in each of the past five years.

The estimated cost of support to renewable technologies burning wood for fuel under three of the schemes in each of the last financial years is shown in the table to the nearest million pounds (in nominal prices). Wood burning is not supported by any technology eligible for support under the Feed-in Tariff scheme.

For the Renewables Obligation, information is not available on the value of support specifically for renewable technologies burning wood. Therefore, the figures provided are the support for technologies capable of burning wood, but other biomass fuels may have been used. The figures for the Contracts for Difference reflect total payments, including to biomass projects, made during the first two financial years of the scheme’s operation and reported by the Low Carbon Contracts Company, the scheme administrator, in its annual reports. Payments by technology type are not reported separately. Wood fuel burning is subsidised under the Domestic RHI biomass tariff and the Non-domestic tariffs for biomass and solid biomass CHP. This assumes all fuel for CHP is wood, as it is not possible to disaggregate wood fuel for CHP. Other types of solid biomass fuel are also eligible for RHI CHP support.

[1] The Renewables Obligation figures are based on Ofgem’s certificate report as at 23/08/2018 from their Renewables and CHP Register.
