3 Where, under regulation 4, S provided to the Settlement Body a forecast of gross demand for year X (other than a forecast of zero gross demand) S must make a payment to the Settlement Body in respect of each standstill month of year X on account of its liability under regulation 6(1) (a “monthly capacity market supplier charge”).
4 Where, in respect of year X—
(a) S supplies electricity as mentioned in regulation 6(1), but
(b) S did not provide to the Settlement Body a forecast as mentioned in paragraph (3) because it was not an electricity supplier on the 1st June before the start of year X,
S must pay a monthly capacity market supplier charge to the Settlement Body in respect of each month of year X for which the calculation of such charges is carried out using actual supplier shares.
5 If a payment trigger event has occurred, the Settlement Body must,by no later than 12 working days before the commencement of the post-standstill collection month—
(a) determine the amount of standstill collection period supplier charge which is payable by each electricity supplier in respect of the standstill collection period of year X (“collection period X”);

(ii) where the amount determined for S under sub-paragraph (b) is a negative amount, a credit note for the amount determined (as a positive amount); or
(iii) where the amount determined for S under sub-paragraph (b) is 0, a notice informing the supplier a standstill collection period supplier charge payment is not required.
6 The Settlement Body must, by no later than the tenth working day of the post-standstill collection month, issue an invoice to each electricity supplier required to make a mutualisation payment in respect of the collection period X under regulation 7A(4) for the amount determined for that supplier under regulation 7A(5) in respect of collection period X.
7 Unless a payment trigger event has occurred, where S has been given notice of a schedule of post-standstill payments in respect of year X in accordance with regulation 6(4A) or (4B), S may pay some or all of the capacity market supplier charge in respect of a standstill month of year X (“month SM”) by paying an amount equal to or less than the amount specified in the schedule in respect of month SM to the Settlement Body.
8 A payment of monthly capacity market supplier charge to the Settlement Body by S in respect of month SM before the date S was given notice of a schedule of post-standstill payments which included month SM is treated as a payment by S under paragraph (7) in respect of month SM.
9 Interest (if any) which accrues in respect of a payment under paragraph (7) (including a payment to which paragraph (8) applies) is treated as a payment by S under paragraph (7) in respect of month SM.
10 A payment under paragraph (7) in respect of a standstill month (“month SM”) does not discharge S’s obligation to pay any amount determined under regulation 7A or to make a reconciliation payment for a standstill collection period or delivery year which includes month SM.
11 If the Settlement Body is required to reduce the amount of capacity payments payable in respect of collection period X because the total amount of capacity payments payable in respect of this period exceeds the total amount of capacity market supplier charges collected in respect of this period, the Settlement Body must, by no later than 40 working days after the date on which it was required to make this reduction, issue to each electricity supplier required to make a supplementary mutualisation payment under regulation 7A(8) an invoice for the amount determined for that supplier under regulation 7A(9) in respect of collection period X.
12 The standstill collection period supplier charge payable by S under paragraph (5)(a) is determined by—
(a) carrying out the calculations in paragraph 3 of Schedule 1 (where the necessary data is available) to redetermine the amount of monthly capacity market supplier charge payable by each electricity supplier in respect of the standstill collection period (repeating these calculations if they have already been carried out in respect of year X); and
(b) calculating the sum of the amount of MCMSCsm calculated for S under paragraph 4 of Schedule 1 in respect of each month of year X which is a standstill month, substituting the calculations remade under sub-paragraph (a) (if any) for any previous calculations under paragraph 3 of Schedule 1 in respect of these months.
13 The amount payable under paragraph (5)(b) (“AP”) must be calculated in accordance with the following formula—
AP=SSPSC−SCP
14 In paragraph (13)—
“SSPSC” means the amount payable by S under paragraph (5)(a); and

received by the Settlement Body exceeds the total amount of capacity payments (including residual capacity payments) payable to capacity providers.
12 The Settlement Body must calculate the amount of that excess (the “surplus”) and each electricity supplier who made a mutualisation payment (including a supplementary mutualisation payment) in respect of collection period X is entitled to be credited with a share of the surplus (a “mutualisation credit”), such that the surplus is distributed between such electricity suppliers in the same proportions as they made mutualisation payments (including supplementary mutualisation payments).
