Scheme amendments 2019
The Northern Ireland (Regional Rates and Energy) Act 2019 introduced a new set of tariffs for all small and medium sized biomass boilers accredited to the scheme.
Further detail on the 2019 amendments is available in documents published on the consultation page on DfE’s website.
The 'tiered' tariff system
This ‘tiered’ tariff structure runs on a 12 month basis, starting with an installation’s date of accreditation or its anniversary.
During this 12 month period, the initial amount of heat generated by the installation running at its installation capacity for 1,314 hours will be paid at the higher Tier 1 tariff.
Any further heat generated during this 12 month period will be paid at the lower Tier 2 tariff, up to a maximum of 400,000kWhth.
On the first anniversary of the date of accreditation after 1 April 2019, the amount of generated heat will be taken to start again from zero and the tiered tariffs will be applied until the next anniversary of the installation’s accreditation or a further change in the legislation.
Meter readings and payments
You must continue to give meter readings so that the following year’s payments can be calculated accurately.
When you give your meter readings each quarter, Ofgem can work out how much heat you have generated cumulatively over the 12 months since your anniversary date.
Ofgem will tell you via a message on the RHI Register if you have reached your 400,000 kWhth cap based on your submitted meter readings and pay you for all eligible heat output up to this cap.
If you have generated more than the 400,000kWhth cap in the relevant year and been paid for it, you will get no further payments up to your anniversary date.
However, you must continue to give meter readings even after passing this cap.
More actions
No more action is needed at present. You should continue to give your meter readings and keep to your ongoing obligations as usual. If any more information is needed you will be contacted directly.
