	(b)	if the customer has been entitled under a retail contract to gas supply through the delivery point for the 12 months immediately preceding the relevant day, the customer's annual gas consumption level for the delivery point is—
	(i)	the actual gas supply, expressed in terajoules, through the delivery point for that 12 month period as measured by the meter at the delivery point; or
	(ii)	if the measurement of the gas supply by the meter has been significantly affected by inaccuracies during that 12 month period—the estimated gas supply, expressed in terajoules, through the delivery point for the 12 months immediately following the relevant day;
	(c)	if the customer has not been entitled under a retail contract to gas supply through the delivery point for the 12 months immediately preceding the relevant day, the customer's annual gas consumption level for the delivery point is the estimated gas supply, expressed in terajoules, through the delivery point for the 12 months immediately following the relevant day;
	(d)	an estimate is to be made for the purposes of paragraph (b) or (c) taking into account relevant past gas consumption levels, the gas consumption level of plant and equipment to use gas delivered through the delivery point, the operations for which gas is required to be supplied through the delivery point and other relevant factors;
	(e)	the determination of the actual or estimated gas supply through the delivery point may be by agreement between the customer and the gas entity or, failing such agreement, will be a matter for the decision of the Commission on application to the Commission by the customer or the entity;

	(i)	the customer ceases to be entitled to gas supply through the delivery point under a retail contract with the gas entity; or
	(ii)	a subsequent determination is made under this regulation of the customer's annual gas consumption level for the delivery point,
whichever first occurs;
	(g)	at least 12 months must elapse from the relevant day before a subsequent determination is made under this regulation of the customer's annual gas consumption level for the delivery point.

the relevant day, in relation to the determination of the customer's annual gas consumption level for the delivery point, means—
	(a)	the day on which the determination is made; or
	(b)	if some earlier or later day is agreed to by the customer and the gas entity, or is decided on by the Commission, as the relevant day for the purposes of the determination—that day.

	(i)	the charge is a specified amount for gas supplied by the customer to another person during a period through an inset distribution system; and
	(ii)	the charge does not exceed an amount determined as follows:

where—
A is the amount to be determined;
B is the cost to the customer of the gas supplied to the inset distribution system during the period;
C is the quantity of gas drawn from the system by the other person during the period (or a reasonable estimate of the quantity);
D is the total quantity of gas drawn from the system during the period; and
	(iii)	the customer gives the other person, when charging the other for the supply of gas, written notice of—
	(A)	the cost to the customer of the gas supplied to the inset distribution system during the period; and

	(4)	An energy productivity activity undertaken by a retailer for the purposes of achieving a primary subtarget or secondary subtarget under regulation 21 is taken to be included as an energy productivity activity undertaken by a retailer for the purpose of achieving its EPT under this regulation.
	(5)	If—
	(a)	a retailer undertakes energy productivity activities in a year sufficient to achieve at least 90% of its EPT for that year but does not achieve its EPT; and
	(b)	in the subsequent calendar year this Part no longer applies to the retailer as a result of the operation of regulation 16(1),
the retailer must undertake energy productivity activities in the subsequent year to account for its energy productivity shortfall from the previous year.
	(6)	If—
	(a)	a retailer fails to achieve its EPT with respect to any year; and
	(b)	the retailer—
	(i)	pays a shortfall penalty in accordance with the requirements of section 91A of the Act with respect to that failure; or
	(ii)	is subject to a penalty on account of a prosecution in respect of that failure,
the energy productivity shortfall to which the shortfall penalty or prosecution relates will no longer apply to the retailer.
	(7)	In this regulation—
energy productivity shortfall means the difference between the EPT that applies to the retailer for a year and the amount of normalised gigajoules actually achieved (in accordance with this Part) by that retailer in that year through the conduct of energy productivity activities.
21—Energy productivity activities—subtargets

	(3)	Despite subregulation (2)—
	(a)	if a retailer fails to achieve a primary subtarget in a year, the Commission must ensure that the energy productivity shortfall is added—
	(i)	if an equivalent primary subtarget applies to the retailer in the subsequent year—to that primary subtarget; or
	(ii)	in any other case—to the EPT that applies to the retailer in a subsequent year; and
	(b)	if a retailer fails to achieve a secondary subtarget in a year, the Commission must ensure that the energy productivity shortfall is added—
	(i)	if an equivalent secondary subtarget applies to the retailer in the subsequent year—to that secondary subtarget; or
	(ii)	in any other case—to the EPT that applies to the retailer in a subsequent year.
	(4)	If—

Y is the number of NERL retailers that retail gas to small customers at the commencement of the period to which the annual administration fee relates.
	(2)	For the purposes of section 59E(7)(c) of the Act, the costs determined by the Minister of the administration in relation to the retailing of gas in South Australia of Part 9 of the National Energy Retail Law (South Australia) by the Australian Energy Market Commission established by the Australian Energy Market Commission Establishment Act 2004 are prescribed.
	(3)	If a NERL retailer commences retailing gas to small customers as a NERL retailer during a period to which an annual administration fee relates, the annual administration fee for the NERL retailer is to be adjusted by multiplying—
	(a)	the annual administration fee that would have been payable by the NERL retailer had it been retailing gas as a NERL retailer during the whole of the relevant period; and
	(b)	the proportion that the number of whole months between the commencement of retailing and the end of the relevant period bears to 12 months.
	(4)	If a relevant entity within the meaning of section 33 of the National Energy Retail Law (South Australia) Act 2011 had, before 1 February 2013, paid (as a gas entity under the Gas Act 1997) to the Commission a licence fee under section 20 of the Act in respect of the whole or any part of the period commencing on 1 February 2013 and ending on 1 February 2014, the Commission must determine an amount in relation to the licence fee that is to be offset against the annual administration fee that applies to the entity, or credited or refunded to the entity (as determined by the Commission).
