Electricity Transmission Regulations 1996

In this regulation —

the demand exit rate for the group of connections in respect of a user’s access agreement for a half hour is determined by applying the following formula:

where —

DERA (in kW) is the demand exit rate for the group of connections in respect of the access agreement for the half hour;

PTExit_i (in kW) is the average rate at which electricity is transferred at exit point_i from the electricity transmission network during the half hour under the access agreement;

LFExit_i (a rate) is the loss factor for exit point_i determined under regulation 20;

the variable “i” represents an exit point which is one of the group of connections;

the variable “n” represents the number of exit points in the group of connections;

the demand entry rate for the group of connections in respect of an access agreement for a half hour is determined by applying the following formula:

where —

DER (in kW) is the demand entry rate for the group of connections in respect of the access agreement for the half hour;

PTEntry_j (in kW) is the average rate at which electricity is transferred at entry point_j to the electricity transmission network during the half hour under the access agreement;

LFEntry_j (a rate) is the loss factor for entry point_j determined under regulation 20;

the variable “j” represents an entry point which is one of the group of connections;

the variable “n” represents the number of entry points in the group of connections;

the standby generation reservation (in kW) for a group of connections is the aggregate rate at which the Electricity Generation and Retail Corporation may be required to transfer standby power to the connections in the group of connections under the access agreement;

the excess demand (in kW) in respect of a group of connections for a half hour is equal to —

the demand exit rate for the group of connections for the half hour;

minus

the demand entry rate for the group of connections for the half hour;

minus

the standby generation reservation for the group of connections for the half hour,

but if the result of this calculation is negative, then the excess demand in respect of the group of connections for the half hour is zero;

if the excess demand in respect of a group of connections for a half hour is not zero, then an excess demand period in respect of the group of connections commences at the start of that half hour, except if that half hour already falls within an excess demand period in respect of the group of connections;

each excess demand period in respect of a group of connections includes 336 half hours.

If an excess demand period in respect of a group of connections in respect of a user’s access agreement commences during a month, then the excess standby generation capacity charge payable by the user in respect of the group of connections for the month is determined by applying the following formula:

where —

ESCC (in $) is the excess standby generation capacity charge in respect of the group of connections for the month;

E_i (in kW) is the highest excess demand in respect of the group of connections for any half hour falling within excess demand period_i;

ESGF (in $/kW) is the excess standby generation capacity fee set out in the fee schedule for the financial year in which the month falls;

the variable “i” represents an excess demand period in respect of the group of connections that commenced during the month;

the variable “n” represents the number of excess demand periods in respect of the group of connections that commenced during the month.
