The Renewable Heat Incentive Scheme Regulations 2018

Regulation 60

SCHEDULE 7 E+W+S Degression

Calculation of B E+W+S

1.—(1) For the purposes of regulation 60, B is calculated in relation to a tariff category and an assessment date as follows.

(2) For the purposes of this paragraph—

(a) the first test is met in relation to an assessment date in the first column of Table 1 if the forecast for total expenditure as at that date exceeds the figure specified for that assessment date in the corresponding entry in the second column of Table 1;

(b) the second test is met in relation to an assessment date if C, as calculated in accordance with paragraph 2 of this Schedule, is 0.10 or more.

(3) B is 0 unless the circumstances set out in sub-paragraph (4) apply.

(4) B is 0.05 if, in relation to the assessment date—

(a) the first test is met; and

(b) the second test is met.

Calculation of C E+W+S

2.—(1) For the purposes of regulation 60, C is calculated in relation to a tariff category and an assessment date as follows.

(2) For the purposes of this paragraph—

(a) the first test is met in relation to an assessment date in the first column of the relevant table if, as at that assessment date, the forecast for expenditure in relation to that tariff category exceeds the figure specified for that assessment date in the corresponding entry in the second column of that table;

(b) the second test is met in relation to an assessment date if, as at that assessment date, the increase in expenditure forecast applicable to that tariff category is at least 50% of, but less than 150% of, the figure specified for that assessment date in the corresponding entry in the third column of the relevant table (“the anticipated increase figure”);

(c) the third test is met in relation to an assessment date if, as at that assessment date, the increase in expenditure forecast applicable to that tariff category is at least 150% of the anticipated increase figure;

(d) in relation to an assessment date other than the assessment date which falls on 30th April 2018, the fourth test is met if during the tariff period that immediately preceded the tariff period in which the assessment date falls, the value of C applicable to that tariff category was 0.10 or more,

where the “relevant table” means whichever of Tables 2 to 9 in this Schedule is applicable to that tariff category.

(3) C is 0 unless the circumstances set out in sub-paragraph (4) or (5) (a), (b) or (c) apply.

(4) In relation to the assessment date which falls on 30th April 2018, C is 0.10 if—

(a) the first test is met; and

(b) the second or third test is met.

(5) In relation to any subsequent assessment date—

(a) C is 0.10 if—

(i) the first test is met; and

(ii) the second test is met, whether or not the fourth test is met;

(b) C is 0.10 if in relation to the assessment date—

(i) the first test is met; and

(ii) the third test is met but the fourth test is not met; and

(c) C is 0.20 if in relation to the assessment date—

(i) the first test is met;

(ii) the third test is met; and

(iii) the fourth test is met.
