HOW THE SCHEME WORKS

The RHI provides financial support for renewable heat technologies for the lifetime of the installation (to a maximum of 20 years). Payments will be made on a quarterly basis and determined by the actual heat output of the system therefore heat meters will be required for each installation.

Under the Renewable Heat Incentive Scheme Regulations (Northern Ireland) 2012, the RHI tariffs must be adjusted annually in line with the retail price index (RPI) for the previous calendar year. DETI must make the necessary calculations and publish the revised tariffs and Ofgem, as administrators of the scheme, must take account of the tariff changes and ensure they are applied.

The table below details the supported technologies and the tariffs at 1 April 2014. These tariffs have been adjusted in line with RPI. The increase in the RPI for the calendar year 2013 was 2.7 per cent. The tariffs are therefore increasing by this amount, with the resulting figure being rounded, in line with regulations, to the nearest tenth of a penny, with any twentieth of a penny being rounded upward.

This applies to installations using solid biomass; municipal solid waste.
