Periodic support payments for new solid biomass CHP systems39D

1

This regulation applies where—

a

an accredited RHI installation which is, or includes, a new solid biomass CHP system has a tariff start date on or after 1st August 2016; and

b

the power efficiency of the CHP system is lower than 20%.

2

Subject to regulations 23(2) and 39C, the periodic support payment for the installation in respect of each quarterly period is to be calculated in accordance with the following formula—

$$\left(\text{A}\times \text{B}\right)+\left(\left(1-\text{B}\right)\times \left(\text{C}\times \text{D}\right)\right)+\text{E}$$

where—

1. a

   A is the periodic support payment calculated in accordance with regulation 39A or 39B in respect of the heat generated using solid biomass in the CHP system which meets the requirements of regulation 9A;

2. b

   B is the figure, expressed as a decimal, derived from multiplying the power efficiency of the CHP system by 5;

3. c

   C is the tariff, calculated in accordance with regulations 37 to 37D, that would apply if the CHP system ceased to be certified under CHPQA;

4. d

   D is the kWhth of heat generated using solid biomass in the CHP system which meets the requirements of regulation 9A, calculated in accordance with regulation 39A(2)(b)(ii) or 39B(2)(b);

5. e
   insofar as D relates to heat calculated in accordance with regulation 39A(2)(b)(ii), regulation 40 applies to the periodic support payment figure given by the calculation $\left(\text{C}\times \text{D}\right)$;
6. f

   E is the sum of the periodic support payments, calculated in accordance with regulation 39A or 39B, in respect of any heat generated by the installation using biogas, biomass contained in waste, or other biomass used in a CHP system where regulation 9 applies.

For the purposes of this regulation, the power efficiency of a CHP system is to be determined for each 12 month period beginning with 1st August and ending with 31st July (or for any part of that period) and is the power efficiency stated—

a

on the certificate issued under CHPQA in the calendar year in which that period begins; or

b

on the most recent certificate issued under CHPQA where a certificate has not been issued in the calendar year in which that period begins.
