Highlights
The UK government has introduced the RHI scheme to encourage the switch to heat generated by renewable sources. This subsidy applies to qualifying biomass installations:

  • Up to 8.3p paid per kWh of useful heat
  • Heat output to be metered and the support calculated from the amount of eligible heat, multiplied by the tariff level
  • Tariff is dependent on the size of boiler
  • Installations over 45kW do not require certification under the Microgeneration Certification Scheme (MCS) to qualify
  • Payable to owner of the equipment
  • Payable on a quarterly basis, guaranteed for 20 years.
  • Immediate eligibility (equipment commissioned on or after 15 July 2009)

Renewable Heat Incentive (RHI) Scheme

Introduction
Increasing renewable heat is key to the UK meeting its renewable energy targets, reducing carbon emissions, ensuring energy security and helping to build a low carbon economy.

The introduction of the Renewable Heat Incentive (RHI) scheme by the UK Government is intended to increase significantly the proportion of heat that is generated from renewable sources. By encouraging a switch from fossil fuels, this will contribute towards the UK’s wider carbon reduction goals. The RHI is intended to compensate for the higher cost of renewable heating technologies, which will help make renewable heating an option for all.

A summary of the main points applicable to biomass boiler installations are outlined below. For a the full Renewable Heat Incentive (RHI) publication, please click here


Eligible biomass installations
In order to be eligible to claim the RHI, equipment must be:

  • a new installation;
  • first commissioned on or after the 15 July 2009;
  • generating heat for an eligible use (see below); and
  • metered output.


Eligible uses of heat
The RHI will only support ‘useful’ heat. This is defined as follows:
  • Heat supplied to meet a justifiable heating requirement;
  • Load should be an existing or new heating requirement i.e. not created artificially, purely to claim the RHI; and
  • Acceptable uses are space, water and process heating


Payments
RHI payments will:

  • only be made to the ‘owner’ of the biomass installation through an application made directly to Ofgem;
  • be calculated by multiplying the appropriate tariff by the amount of eligible heat; and
  • be made over a period of 20 years on a quarterly basis following the submission of the required periodic information

Example – Small biomass
A qualifying 180kW biomass installation in a school. Assumed operation - 10 hrs per day; five days per week; 35 weeks per year. Assumed generation of 315MWh of useful heat per annum from 70 tonnes of wood pellet. Approximate installed capital cost £75k:

RHI calculation:

Tier break              = 180 x 1,314       = 236,520 kWth

Tier 1:     236,520 @ 8.3p                   = £19,631.16
Tier 2:       78,480 @ 2.1p                   = £  1,648.08
                315,000                                    £21,279.24


If generated evenly throughout the year, payments will be received of £5,319.81 per quarter

Fuel costs:
70 tonnes of pellet x £190 per tonne* = £13,300

Benefit:
Energy costs covered AND £7,979.24 cash benefit* AND, assuming no change in fuel price, every year for 20 years.
*based on typical fuel price at April 2012




Tariff (based on OFGEM guidance, issued June 2011)
Tariff name Eligible size Tier 1 rate
(pence/kWh)
Tier2 rate
(pence/kWh)
Small biomass Less than 200kWth 8.3 2.1
Medium biomass 200 kWth and above; less than 1,000 kWth 5.1 2.1
Large biomass 1,000 kWth + 1.0
Tier 1 is on output below the Tier Break; Tier 2 is on output above the Tier Break
Tier Break (annually) = installed capacity x 1,314 peak load hours

The GreenTec wood pellet boiler range is manufactured in-house in Leicester. The boilers are exempt appliances which allow use in Smoke Controlled Areas (under the Clean Air Act) (models 150kW and above) and, being of modular design, offer an extremely versatile configuration of fuel feeds along with a much reduced footprint compared to the majority of biomass boilers. These pellet boilers are available over a range of outputs from 50 kW to 300 kW
