Renewable Heat Incentive Update

RHI (Renewable Heat Incentive) UPDATE – 26 OCTOBER 2011

DECC was planning to launch the Renewable Heat Incentive (RHI) for non-domestic generators on 30 September 2011. State aid approval is a necessary condition for the scheme to go ahead. As part of that process, the European Commission expressed concerns that the large biomass tariff was set too high.

The Commission has now given State Aid approval to the RHI subject to the large biomass tariff being reduced from 2.7p per KWh to 1p per KWh. Revised regulations have now been re-laid in Parliament to reflect the required amendment to the tariff for large scale biomass. We hope to open the scheme to applications by the end of November 2011, subject to Parliamentary approval.


Please note that the tariff reduction is only for “large biomass”. This is for installations above 1000 kW’s which may heat 50 or more houses e.g. a small village and larger e.g. Biomass power station

  1. Hi Richard two thoughts a wteand to share:re hotel, I think I know the project and if its the one I think then the client detemined the boiler rating and connectoin. 2 x bags of pellets per day is about right for a 25kW nominal boiler its doing what its abel to do. ofcourse that you have to carry 2 bags every day through the house is the key flaw to the stove-boiler product. although most seem to suffer from being too fragile to last a Uk winter or two.the key thought is that the client wont buy from you if you tell him he is wrong.on the bigger boiler, as we have discussed on other forums: the succesful biomass installtion relies on many aspects being correct. key are: boiler to match avaiable fuel, fuel store being correctly sized adn positined to accept economic deliveries. fuel store being adequate to handle the fuel and deliver to the boiler, buffer sized so that boiler does not cycle excessively. boiler and buffer and heating controls integrated so that cycling does not occur dueto hihg return temperature. flue correctly sized adn installed to remove combustion products safely and not produce incorrect draft on the boiler. boiler positioned to allow proper maintenance in commercial jobs, heating controls (BMS) correctly programmed to meet design requirements. heat users educated onwhat to expect form heating. boier opeator educated on how to service and maintain boiler. if any one of these is not optimal then the system will not work and the boier (usually) is blamed.what has this to do with oversized boiler? a correctly instllalled boiler with correctly sized buffer and controls doesnt mind being over sized it just runs less and has cost more to put a real boier installer with a tied product range I select teh boeir with the best fit to the cleints needs from what I have available. which means a 100kW boiler for a 65kW nominal load. in rhi terms this may give the client more income opportunity if they use more heat. it may cost more than competitors products ( different size or otherwise) but clients buy form me becasue i do it right and support the install never because i am cheapest becasue i never will be. OTOH i suspect my still working and in use after 3 years percentage is a lot higher than the national average alas I have lost contact with some old customers .With the RHI there are also lots of undersized boilers going in at the 200kW cut off. so swings and roundabouts.
