The Renewable Heat Incentive Scheme (Amendment) Regulations 2014

Periodic support payments for CHP systems using biomass or biogas in combination with other sources of energy

38.  After regulation 39A insert—

“Periodic support payments for CHP systems using biomass or biogas in combination with other sources of energy

39B.— (1) This regulation applies to participants who own an accredited RHI installation which is a CHP system using solid biomass or biogas in combination with other sources of energy.

(2) Subject to regulation 23(2) and 39C, where this regulation applies, participants shall be paid periodic support payments for the installation in respect of each quarterly period calculated in accordance with the following formula—

where—

(a)

A is the tariff in respect of any heat generated by the installation using solid biomass determined in accordance with regulations 37 to 37D;

(b)

B is the kWhth of heat generated by the installation from solid biomass burned in a combustion unit to which regulation 9(2)(b) or 9A applies or solid biomass contained in waste burned in a combustion unit to which regulation 9(2)(b) applies, calculated in accordance with paragraph (3), and which is used for eligible purposes;

(c)

C is the tariff in respect of any heat generated using biogas determined in accordance with regulations 37 to 37D;

(d)

D is the kWhth of heat generated by the installation from biogas, calculated in accordance with paragraph (4), and which is used for eligible purposes;

(e)

E is the heat in kWhth directed from the installation or delivered from any other source to the biogas production plant which produced the biogas combusted in the relevant quarterly period (other than heat contained in feedstock to produce biogas by anaerobic digestion) or, where there is no such heat, 0.

(3) B shall be calculated in accordance with the following equation—

where—

(a)

H_CHP is the total heat in kWhth generated by the installation in the relevant quarterly period which is used for eligible purposes;

(b)

FI_B is the energy content of the solid biomass (excluding the energy content of any fossil fuel contamination in such biomass) to which regulation 9(2)(b) or 9A applies or solid biomass contained in waste burned in a combustion unit to which regulation 9(2)(b) applies and used in the installation to generate heat and power during the relevant quarterly period;

(c)

FI_other is the energy content of all other fuel used in the installation in the relevant quarterly period, including the energy content of any fossil fuel contamination or fossil fuel used in the CHP system for permitted ancillary purposes in accordance with regulation 28 or 29.

(4) D shall be calculated in accordance with the following equation—

where—

(a)

H_CHP is the total heat in kWhth generated by the installation during the relevant quarterly period which is used for eligible purposes;

(b)

FI_D is the energy content of the biogas used in the installation during the relevant quarterly period;

(c)

FI_other is the energy content of all other fuel used in the installation during the relevant quarterly period, including the energy content of any fossil fuel used in the CHP system for permitted ancillary purposes in accordance with regulation 28 or 29.

CHP systems accredited in relation to the Renewables Obligation

39C.— (1) No periodic support payments may be made in relation any heat generated by any capacity of a CHP system to which paragraph (2) or (3) applies.

(2) This paragraph applies to capacity which generated heat and electricity before 1st April 2013 and which—

(a) uses solid biomass or solid biomass contained in waste to generate heat and electricity, and

(b) forms part of a generating station which—

(i) is accredited under the Renewables Obligation Order 2009(1) or the Renewables Obligation (Scotland) Order 2009(2), and

(ii) is or at any time since it was so accredited, has been a qualifying combined heat and power generating station within the meaning of article 2 of either of those Orders.

(3) This paragraph applies to capacity which first generates heat and electricity on or after 1st April 2013 and—

(a) which—

(i) uses solid biomass to generate heat and electricity;

(ii) forms part of a generating station which is accredited under the Renewables Obligation Order 2009 or the Renewables Obligation (Scotland) Order 2009, and

(iii) is capacity in respect of which a declaration under article 28(7) of either of those Orders has been made; or

(b) which—

(i) uses solid biomass contained in waste to generate heat and electricity;

(ii) forms part of a generating station which is accredited under the Renewables Obligation Order 2009 or the Renewables Obligation (Scotland) Order 2009; and

(iii) forms part of a generating station which is or at any time since it was so accredited, has been a qualifying combined heat and power generating station within the meaning of article 2 of either of those Orders.”.
