(a)“collateral” is to be construed in accordance with regulation 19(7);
(b)“relevant payment” means any payment which an electricity supplier is required to make by virtue of regulation 7(1), 8(2), 10(1), 13(3), 16(3)(a) or 17(6);
(c)the reference period is the most recent period, occurring before the mutualisation notice (to which the reference period relates) has been issued, of 30 consecutive days in respect of which the BSCCo has carried out an Initial Volume Allocation Run; and
(d)the amount of electricity supplied by an electricity supplier in a reference period is the amount of electricity which the BSCCo determines, on the basis of the most recent BSC volume allocation run which the BSCCo has carried out in relation to each day in that period, as the amount of electricity supplied by that supplier in that reference period.
18.—(1) Where the revenue collection counterparty has issued a mutualisation notice in respect of a failure of an electricity supplier (“the defaulting supplier”) to make a relevant payment (“the relevant default”) and subsequently recovers any amount from that supplier in respect of that failure, that amount must be paid to electricity suppliers who were required to pay mutualisation amounts in respect of that failure in accordance with paragraphs (2) and (3).
(2) The amount which the revenue collection counterparty must, by virtue of paragraph (1), pay an electricity supplier who was required to pay a mutualisation amount (“the non-defaulting supplier”) is the amount given by—
where—
AR is the amount recovered from the defaulting supplier in respect of the relevant default, including any interest paid by the defaulting supplier in respect of that failure;
SU is the mutualisation amount which the non-defaulting supplier was required to pay in respect of the relevant default; and
AU is the total amount of mutualisation payments which were required to be paid by all non-defaulting suppliers in respect of the relevant default.
(3) Any amount which the revenue collection counterparty is required to pay by virtue of paragraph (1) must be paid by the 15th working day after the day on which it recovers the amount to be paid.
(4) In paragraph (1), “relevant payment” means any payment which an electricity supplier is required to make by virtue of regulation 7(1), 8(2), 10(1), 13(3), 16(3)(a) or 17(6).
19.—(1) This regulation applies at all times after an electricity supplier makes an electricity supply in a quarterly obligation period in respect of which it is required to make an interim rate payment.
(2) Where this regulation applies the supplier must ensure that, on any day, the revenue collection counterparty holds sufficient collateral from the supplier to meet the supplier’s collateral requirement for that day.
(3) The supplier’s collateral requirement for a day (“the relevant day”) is determined by reference to the most recent period of 21 consecutive days prior to the last working day before the relevant day, in respect of which the BSCCo had carried out a BSC volume allocation run (“the relevant period”).
(4) For each day in the relevant period, the amount of electricity supplied by the supplier on that day, less any amount of EII excluded electricity supplied by that supplier on that day, (both as determined on the last working day before the relevant day), multiplied by the interim levy rate which applies in relation to the relevant day, gives a relevant amount.
(5) The sum of the relevant amounts is the supplier’s collateral requirement for the relevant day.
(6) The supplier is not to be treated as having breached its obligation under paragraph (2) where, after the first occasion on which it provided sufficient collateral to the revenue collection counterparty to meet its collateral requirement for a day—
(a)the amount of that supplier’s collateral held by the revenue collection counterparty fell below that supplier’s collateral requirement for a subsequent day; and
(b)by the second working day (“the cure day”) after that subsequent day, the supplier provides sufficient collateral to the revenue collection counterparty to meet its collateral requirement for the cure day.
(7) Collateral may be provided in the form of—
(a)cash;
(b)appropriate letters of credit; or
(c)a combination of the two.
(8) For the purposes of this regulation—
(a)collateral is held by the revenue collection counterparty where it is provided to the revenue collection counterparty and not called (within the meaning of regulation 21);
(b)the amount of electricity supplied by a supplier on any day is the amount which the BSCCo determines, on the basis of the most recent BSC volume allocation run carried out by the BSCCo in relation to that day, as the amount of electricity that the supplier supplied on that day; and
(c)the interim levy rate which applies in relation to a day is the interim levy rate which applies in relation to that day by virtue of regulation 7(3).
(9) Regulation 20 makes further provision about appropriate letters of credit.
20.—(1) For the purposes of regulation 19, a letter of credit is appropriate if—
(a)it is issued by a person who holds a required rating; and
(b)it is provided on terms which the revenue collection counterparty considers are appropriate.
(2) The terms which the revenue collection counterparty may consider are appropriate under paragraph (1)(b) include terms relating to—
(a)the manner in which any demand for payment under a letter of credit is to be made;
(b)the manner in which any payment under a letter of credit is to be made; and
(c)requirements about the holding of funds to meet demands for payment under a letter of credit.
(3) Where an electricity supplier has provided the revenue collection counterparty with a letter of credit issued by a person who ceases to hold a required rating that letter will not constitute an appropriate letter of credit from the 10th working day after the day on which that person ceases to hold that rating.
(4) Subject to paragraph (5), a person holds a required rating if that person has been assessed by—
(a)Fitch Ratings as having a short term debt rating of “F1” or better;
(b)Moody’s as having a short term debt rating of “P-1” or better; or
(c)Standard and Poor’s as having a short term debt rating of “A-1” or better.
(5) Where the revenue collection counterparty is of the opinion that the requirement that appropriate letters of credit must be issued by persons holding a short term debt rating mentioned in paragraph (4)(a) to (c) is too onerous in the circumstances, and subject to having regard to its duty under regulation 28(1), it may issue a notice to BM registered electricity suppliers specifying alternative short term debt ratings, and that notice shall remain in force until such time as it is withdrawn.
(6) In paragraph (5), “BM registered electricity suppliers” means electricity suppliers who have a BM Unit registered as at the day before the date the notice is issued.
(7) The revenue collection counterparty may withdraw a notice under paragraph (5) (“the first notice”) by issuing a further notice (“the withdrawal notice”) to electricity suppliers who were sent the first notice setting out the date from which the first notice is to be withdrawn (that date being no earlier than 10 working days after the day on which the withdrawal notice is issued).
(8) The revenue collection counterparty must, before the first revenue collection contract is entered into, publish a document setting out the terms of letters of credit which it is likely to regard as appropriate for the purposes of paragraph (1)(b), and must keep any such document under review and publish any revision from time to time.
(9) In this regulation—
“Fitch Ratings” means Fitch Ratings Limited (registered company number 01316230);
“Moody’s” means the corporation known as Moody’s Investors Service Inc., incorporated in the US State of Delaware with the file number 0577904;
“Standard and Poor’s” means the corporation known as Standard & Poor’s Financial Services LLC, incorporated in the US State of Delaware with the file number 4621989.
21.—(1) Collateral provided by an electricity supplier is called by the revenue collection counterparty where the revenue collection counterparty issues a notice to that supplier which sets out the amount of collateral which is to be called.
(2) The revenue collection counterparty may issue a notice under paragraph (1) to an electricity supplier if that supplier has failed to make a relevant payment and—
(a)2 working days have passed since the day on which that supplier should have made that payment; or
(b)the revenue collection counterparty is of the opinion that there is no prospect of that supplier making that payment by 2 working days after the day on which that supplier should have made that payment.
(3) The amount of collateral which may be called by the revenue collection counterparty where a supplier has failed to make a relevant payment is the lesser of—
(a)the amount of collateral provided by that supplier; or
(b)the amount of that relevant payment or, where there is more than one relevant payment which that supplier has failed to make and in respect of which a notice under paragraph (1) could be issued, the sum of all relevant payments in respect of which a notice under paragraph (1) could be issued.
(4) Where the whole or part of a supplier’s collateral which was provided in the form of cash has been called by the revenue collection counterparty, that amount is to be treated as a payment made by that supplier to the revenue collection counterparty at the time that collateral was called.
(5) Where the whole or part of a supplier’s collateral which was provided in the form of a letter of credit has been called by the revenue collection counterparty—
(a)the revenue collection counterparty must take steps to demand payment from the person who provided the letter in the amount of the lesser of—
(i)the amount which can be demanded under that letter, or
(ii)the amount of collateral which has been called; and
(b)the amount which has been paid to the revenue collection counterparty under that letter is to be treated as a payment by that supplier to the revenue collection counterparty made at the time that amount is received by the revenue collection counterparty.
(6) In this regulation “relevant payment” means any payment which a supplier is required to make by virtue of regulation 7(1), 8(2), 10(1), 13(3), 16(3)(a) or 17(6) which has not been made by that supplier by the time that payment should have been made, and which remains unpaid.
22.—(1) Where the collateral provided by an electricity supplier and held by the revenue collection counterparty is more than that supplier’s collateral requirement, that supplier may make a request that the revenue collection counterparty repay or return as much collateral as exceeds the supplier’s collateral requirement by giving a notice to the revenue collection counterparty.
(2) Where a request under paragraph (1) has been received by the revenue collection counterparty, it must, before the 2nd working day after the day on which the request was received, repay or return the lesser of—
(a)the amount requested by the supplier; or
(b)the amount of collateral which the revenue collection counterparty determines exceeds that supplier’s collateral requirement at the time the payment is to be made.
(3) Where a supplier has provided collateral in the form of cash and the revenue collection counterparty holds that sum in an account which bears interest, it must pay to that supplier an amount equal to any such interest earned in relation to that sum within 15 working days of receiving that interest.
