Participants using solid biomass contained in waste E+W+S

37.—(1) This regulation applies to a participant generating heat in an accredited RHI installation from solid biomass contained in waste.

(2) The proportion of solid biomass contained in the waste must be a minimum of 10%.

(3) For the purposes of paragraph (2)—

(a) the proportion of solid biomass contained in the waste is to be determined by the Authority for every quarterly period;

(b) it is for the participant to provide, in such form as the Authority may require, evidence to demonstrate to the Authority's satisfaction the proportion of the energy content of the waste used in any quarterly period which is composed of fossil fuel, to enable the Authority to determine the proportion of solid biomass in accordance with sub-paragraph (c);

(c) the proportion of solid biomass is the energy content of the waste used in any quarterly period to generate heat less the energy content of any fossil fuel of which that waste is in part composed, expressed as a percentage of the energy content of that waste.

(4) The participant may use fossil fuel (other than fossil fuel mentioned in paragraph (3)(c)) in an accredited RHI installation for the following permitted ancillary purposes only—

(a) cleansing other fuels from the accredited RHI installation's combustion system prior to using fossil fuel to heat the combustion system to its normal temperature;

(b) the heating of the accredited RHI installation's combustion system to its normal operating temperature or the maintenance of that temperature;

(c) the ignition of fuels of low or variable calorific value;

(d) emission control;

(e) in relation to accredited RHI installations which are CHP systems, standby generation or the testing of standby generation capacity.

(5) The energy content of the fossil fuel used during any quarterly period for the permitted ancillary purposes specified in paragraph (4) must not exceed 10% of the energy content of all the fuel used by that accredited RHI installation or where the installation is a CHP system, by a combustion unit which supplies energy to that installation from solid biomass contained in waste, to generate heat during that quarterly period.

(6) Without prejudice to paragraph (3)(b), when determining the proportion of solid biomass contained in waste, the Authority may have regard to any information (whether or not produced to it by the participant) if, in its opinion, that information indicates what proportion of the energy content of the waste is composed of fossil fuel.

(7) Where the participant produces to the Authority—

(a) data published by an allocating authority, a waste disposal authority or a waste collection authority, demonstrating that the proportion of municipal waste used by that participant which is composed of fossil fuel is unlikely to exceed 50%; and

(b) evidence that the municipal waste used has not been subject to any process before being used that is likely to have materially increased that proportion,

the Authority may accept this as sufficient evidence for the purposes of paragraph (3)(b) of the fact that the proportion of the municipal waste used which is composed of fossil fuel is no more than 50%.

(8) Where the Authority so requests, the participant must arrange for samples of the waste used (or to be used) in the accredited RHI installation, or of any gas or other substance produced as the result of the use of such waste, to be taken by a person (and analysed in a manner) specified by the Authority, and for the results of that analysis to be made available to the Authority in such form as the Authority may require.

Participants using solid biomass in accredited RHI installations with an installation capacity of 1MWth or above E+W+S

38.—(1) This regulation applies to a participant generating heat from solid biomass, not being solid biomass contained in waste, in an accredited RHI installation with an installation capacity of 1MWth or above.

(2) The participant may use solid biomass contaminated with fossil fuel only where the proportion of fossil fuel contamination does not exceed 10%.

(3) Such contaminated biomass may not be used unless the fossil fuel is present because—

(a) the solid biomass has been subject to a process, the undertaking of which has caused the fossil fuel to be present in, on or with the biomass even though that was not the object of the process; or

(b) the fossil fuel is waste and was not added to the solid biomass with a view to its being used as a fuel.

(4) For the purposes of paragraph (2)—

(a) the proportion of fossil fuel contamination is to be determined by the Authority for every quarterly period;

(b) it is for the participant to provide, in such form as the Authority may require, evidence to demonstrate to the Authority's satisfaction the proportion of fossil fuel contamination; and

(c) the proportion of fossil fuel contamination is the energy content of the fossil fuel with which the solid biomass used in any quarterly period is contaminated expressed as a percentage of the energy content of all solid biomass (contaminated or otherwise) used in that quarterly period to generate heat other than fossil fuel used in accordance with paragraphs (5) and (6).

(5) The participant may use fossil fuel (other than fossil fuel mentioned in paragraph (2)) in the accredited RHI installation for the following permitted ancillary purposes only—

(a) cleansing other fuels from the accredited RHI installation's combustion system prior to using fossil fuel to heat the combustion system to its normal temperature;

(b) the heating of the accredited RHI installation's combustion system to its normal operating temperature or the maintenance of that temperature;

(c) the ignition of fuels of low or variable calorific value;

(d) emission control;

(e) in relation to accredited RHI installations which are CHP systems, standby generation or the testing of standby generation capacity.

(6) The energy content of the fossil fuel used during a quarterly period for the permitted ancillary purposes specified in paragraph (5) must not exceed 10% of the energy content of all the fuel used by that accredited RHI installation or where the installation is a CHP system, by a combustion unit which supplies energy to that installation from solid biomass, to generate heat during that quarterly period.

(7) Without prejudice to paragraph (4)(b), in determining the proportion of solid biomass composed of fossil fuel the Authority may have regard to any information (whether or not produced to it by the participant) if, in its opinion, that information indicates what proportion of the contaminated solid biomass is composed of fossil fuel.

(8) Where the Authority so requests, the participant must arrange for samples of the fuel used (or to be used) in the accredited RHI installation, or of any gas or other substance produced as the result of the use of such fuel, to be taken by a person (and analysed in a manner) specified by the Authority, and for the results of that analysis to be made available to the Authority in such form as the Authority may require.

Participants using solid biomass in accredited RHI installations with an installation capacity of 45kWth and above but below 1MWth E+W+S

39.—(1) This regulation applies to a participant generating heat from solid biomass, not being solid biomass contained in waste, in an accredited RHI installation with an installation capacity of 45kWth and above but below 1MWth.

(2) The participant may use solid biomass contaminated with fossil fuel provided the participant complies with paragraphs (2), (3), (5) and (6) of regulation 38 as well as the requirements of this regulation.

(3) Where solid biomass contaminated with fossil fuel is used in an accredited RHI installation, the participant must keep and provide upon request written evidence including invoices, receipts and such other documentation as the Authority may specify relating to fuel use and fossil fuel used for the permitted ancillary purposes specified in regulation 38(5) and provide this information upon request to the Authority, in such form as the Authority may require, to demonstrate compliance with this regulation.

(4) Without prejudice to paragraph (3), the Authority may have regard to any information (whether or not produced to it by the participant) if, in its opinion, that information indicates what proportion of the contaminated solid biomass is composed of fossil fuel.

(5) Where—

(a) the Authority is not satisfied that the proportion of fossil fuel contamination (within the meaning of regulation 38(4)(c)) does not exceed 10%; or

(b) the Authority is not satisfied as to the matters specified in paragraphs (5) and (6) of regulation 38,

the Authority may require the participant to arrange for samples of the fuel used (or to be used) in the accredited RHI installation, or of any gas or other substance produced as the result of the use of such fuel, to be taken by a person (and analysed in a manner) specified by the Authority, and for the results of that analysis to be made available to the Authority in such form as the Authority may require.
