RHI Tarrifs changed in line with RPI and digression triggers
Biomass reaches degression triger – rates adjusted:
The Department of Energy and Climate Change announced on 29 May 2015 that the degression ‘super trigger’ for biomass had been passed.
This means that the current biomass tariff of 8.93p per kilowatt hour will be reduced by 20% to 7.14p per kilowatt hour for all new applications made from 1 July 2015.
- The tariffs for air source heat pumps, ground source heat pumps and solar thermal are not affected by the 1 July 2015 degression.
-
Legacy applicants are not affected by degression.
