28.—(1) Where the Authority has provided a metering statement for an accredited domestic plant, the RHI payment for that plant for any quarterly period is calculated in accordance with this regulation.

(2) Subject to paragraph (3), the RHI payment for a quarterly period is R, where R is calculated in accordance with the following formula—

where—

(a)

A is the applicable initial tariff or subsequent tariff for the accredited domestic plant;

(b)

B is—

(i)

subject to paragraph (ii), the eligible metered heat for the plant for the quarterly period; or

(ii)

0 if the eligible metered heat is less than 0;

(c)

C is the grant funding deduction for the plant for the quarterly period; and

(d)

D is—

(i)

0 if the quarterly period commences on the tariff start date;

(ii)

0 if the quarterly period commences on any subsequent date and PR is 0 or greater; or

(iii)

PR if the quarterly period commences on any subsequent date and PR is less than 0.

(3) Where R is a figure which is less than 0, the RHI payment for the quarterly period is 0.

(4) Where in any quarterly period, R is a figure which is 0 or higher and the sum of that figure and AP is greater than MaxP, the RHI payment for the quarterly period is calculated in accordance with the following formula—

(5) In this regulation—

“AP” is the sum of all RHI payments payable for heat generated by the accredited domestic plant for the applicable period other than the RHI payment for that quarterly period;

“applicable period” means—

(a)

the 12 month period commencing on the tariff start date or the anniversary of the tariff start date and which includes the quarterly period; or

“MaxP” means the figure calculated in accordance with the following formula—

where—

(a)

E is the applicable initial tariff or subsequent tariff for the accredited domestic plant;

(b)

F is the deemed annual heat generation for the plant for the applicable period; and

(c)

G is the grant funding deduction for the plant for the quarterly period, multiplied by 4; and

“PR” is the value of R for the accredited domestic plant for the quarterly period immediately preceding the period for which RHI payments are being calculated.
