RHI (Northern Ireland)

Northern Ireland RHI scheme suspended to new applications: 29 February 2016

The Department of of Enterprise, Trade and Investment (DETI) has suspended the Northern Ireland RHI scheme to new applications from 29 February 2016.  We continue to administer the Non-Domestic RHI scheme on DETI’s behalf. The Great Britain RHI scheme is unaffected. For further information see our frequently asked questions.

About the scheme

The Northern Ireland Renewable Heat Incentive (RHI) is a government environmental programme that provides financial incentives to increase the uptake of renewable heat. It provides subsidies to eligible non-domestic renewable heat generators and producers of biomethane based in Northern Ireland, payable for 20 years. The Northern Ireland RHI policy and tariff rates are set by DETI.

Other changes to the non-domestic scheme

From 18 November 2015, DETI  introduced a number of changes to the scheme. These include:

  • the allowance of relocation of accredited installations
  • the change of banding and introduction of a tiered tariff for small and medium commercial biomass and a 400,000kWhth annual cap on payments
  • the allowance for certain CHP installations to join the NIRHI which are accredited on the Renewables Obligation.

There have been other minor changes to the scheme, the details of which can be found in NIRHI guidance Volumes 1 and 2.
