	(1)	For the purposes of the definition of annual electricity consumption level in section 4 of the Act, the following provisions apply to the determination of a customer's annual electricity consumption level:
	(a)	the customer's annual electricity consumption level is to be determined for each metered connection point through which the customer has or seeks electricity supply under a retail contract;
	(b)	if the customer has been entitled under a retail contract to electricity supply through the connection point for the 12 months immediately preceding the relevant day, the customer's annual electricity consumption level for the connection point is—
	(i)	the actual volume of the electricity supply, expressed in MW.h, through the connection point for that 12 months period as measured by the meter at the connection point; or

	(c)	if the customer has not been entitled under a retail contract to electricity supply through the connection point for the 12 months immediately preceding the relevant day, the customer's annual electricity consumption level for the connection point is the estimated volume of the electricity supply, expressed in MW.h, through the connection 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 electricity consumption levels, the electricity consumption level of plant and equipment to be powered through the connection point, the operations for which electricity is required to be supplied through the connection point and other relevant factors;
	(e)	the determination of the actual or estimated volume of electricity supply through the connection point may be by agreement between the customer and the electricity 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;
	(f)	a determination under this regulation of the customer's annual electricity consumption level for the connection point continues in operation from the relevant day until—
	(i)	the customer ceases to be entitled to electricity supply through the connection point under a retail contract with the electricity entity; or
	(ii)	a subsequent determination is made under this regulation of the customer's annual electricity consumption level for the connection 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 electricity consumption level for the connection point.
	(2)	In this regulation—
the relevant day, in relation to the determination of the customer's annual electricity consumption level for the connection 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 electricity entity, or is decided on by the Commission, as the relevant day for the purposes of the determination—that day.
4B—Interpretation—definition of small customer
