The main benefit of the RHI is the generation tariff, which is paid for every kilowatt-hour of energy produced. The level of payment varies depending on the technology and the system size, as further described here.
Non-residential Installations
The following tariffs have been published for the initial phase of the scheme:
|
Tariff name

Eligible technology | Eligible sizes | Tariff rate (p/kWh) |
| Small biomass |
Solid biomass; Municipal Solid Waste (incl. CHP) |
Less then 200 kWth | Tier 1: 7.9 |
| Tier 2: 2.0 | |||
| Medium biomass | 200 kWth and above; less than 1000 kWth | Tier 1: 4.9 | |
| Tier 2: 2.0 | |||
| Large biomass | 1000 kWth and above | 1.0 | |
| Small ground source |
Ground-source heat pumps; Water-source heat pumps; Deep geothermal |
Less than 100 kWth | 4.5 |
| Large ground source | 100 kWth and above | 3.2 | |
| Solar thermal | Solar thermal | Less than 200 kWth | 8.5 |
| Biomethane | Biomethane injection & biogas combustion, except landfill gas | Biomethane all scales; biogas < 200 kWth | 6.8 |
Details on how the 'tiers' operate are given here.
The above tariffs are those that will apply at the start of the scheme, so have had one year's RPI uplift added to the tariff levels originally published in the initial design document.
All these tariffs are fixed for a duration of 20 years.
Residential installations
No tariffs have yet been published, apart from indicative levels for the Premium Payment.
Perhaps something can be deduced from the proposed tariff levels within the original consultation document for the Renewable Heat Incentive, which were as follows:
