Application of this Chapter N.I.

47.—(1) This Chapter applies in respect of a supply contract where—

(a) it may reasonably be expected that—

(i) the quantity of energy supplied to the customer at the premises to which the supply contract relates in the 12-month period starting on 1st April 2023 will exceed 0.5 gigawatt hours, or

(ii) the maximum rate at which energy is supplied under the contract at any time will exceed 0.5 megawatts, and

(b) the customer has made arrangements, otherwise than in a supply contract, by virtue of which the customer’s overall financial exposure to the wholesale price of energy supplied to it in any period within a scheme period (the “effective financial exposure”) differs from its financial exposure in that period to the contracted wholesale price under the supply contract (the “contract financial exposure”).

(2) The ways in which a customer may make an arrangement of the kind described in paragraph (1)(b) include entering into—

(a) financial instruments in respect of the wholesale price of energy;

(b) arrangements under which the customer obtains a benefit from the provision of balancing services;

(c) in connection with the electricity scheme, arrangements under which the customer obtains a benefit by exporting electricity to an electricity system.

Adjustment of discount N.I.

49.—(1) In respect of any period and supply contract in respect of which Chapter 1 arrangements apply—

(a) subject to paragraph (d), the “arrangement benefit” is the amount calculated as—

Where—

• CFE is the contract financial exposure

• EFE is the effective financial exposure;

(b) the “unit arrangement benefit” (expressed in p/kWh) is the arrangement benefit (expressed in pence) divided by the supply quantity in respect of that period;

(c) the reference wholesale price applicable to the supply contract in that period is determined as—

Where—

• RWP’ is the price that would otherwise be determined (under regulation 9 or in accordance with regulation 10) as the reference wholesale price;

• UAB is the unit arrangement benefit;

(d) in relation to a variable price contract, if the term {CFE – EFE} in paragraph (a) is negative, the arrangement benefit in respect of that period is zero.

(2) Where this Chapter applies in respect of a supply contract—

(a) the supplier must, as soon as practicable after receiving the customer’s declaration under regulation 48(1)(b), give notice to the customer of each periodic declaration date and the declaration period for each such date;

(b) the customer must, as soon as practicable and in any event within the period of 14 days beginning with each periodic declaration date, determine and send to the supplier a declaration of the amount of the arrangement benefit in respect of the relevant declaration period, unless the arrangement benefit is less than £100 per day of the declaration period;

(c) the supplier must, on the basis of the arrangement benefit declared in each such declaration—

(i) calculate the unit arrangement benefit for the declaration period;

(ii) calculate the reference wholesale price under paragraph (1)(c);

(iii) calculate the base discount under regulation 28 on the basis of that wholesale reference price;

(iv) determine or redetermine its charges for energy supplied in the declaration period on the basis of that discount.

(3) Where this Chapter applies and the customer is party to more than one supply contract, the effect of the Chapter 1 arrangements is to be determined in respect of the supply contracts collectively and the arrangement benefit is to be allocated between the supply contracts on an appropriate basis.

(4) The contract parties may agree a basis on which—

(a) an estimate of the arrangement benefit will be used in determining charges for a billing period before the steps in paragraph (2) are completed, and

(b) a subsequent reconciliation will be made when those steps are completed.
