Electricity Transmission Regulations 1996

A user must use reasonable endeavours to ensure that the energy entry amount for the group of connections in respect of each of its access agreements for each half hour is equal to the energy exit amount for the group of connections for that half hour.

For the purposes of subregulation (3), the revised net amount for the group of connections in respect of a user’s access agreement for a half hour is an amount equal to the energy entry amount for the group of connections for the half hour minus the energy exit amount for the group of connections for the half hour, except where —

that amount is positive and is equal to or less than the permitted tolerance for the group of connections; or

that amount is negative and is greater than or equal to zero minus the permitted tolerance,

in which case, the revised net amount for the group of connections is equal to zero.

The half hourly out of balance charge in respect of an access agreement for a half hour is determined by applying the following formula:

where —

HOBC (in $) is the half hourly out of balance charge in respect of the access agreement for the half hour;

RNA (in kWh) —

if the revised net amount for the group of connections in respect of the access agreement for the half hour is positive, then is equal to that revised net amount minus the permitted tolerance for the group of connections; or

if the revised net amount for the group of connections in respect of the access agreement for the half hour is negative, then is equal to that revised net amount plus the permitted tolerance for the group of connections;

HOBF (in ¢/kWh) is —

if RNA is negative, then the half hourly out of balance (sell) fee set out in the fee schedule for the financial year in which the half hour falls applicable to the half hour; or

if RNA is positive, then the half hourly out of balance (buy) fee set out in the fee schedule for the financial year in which the half hour falls applicable to the half hour.

If the sum of the half hourly out of balance charges for the half hours in a month is negative, then an amount equal to ‑1 multiplied by that sum is payable by the user to the corporation, except if the user is the Electricity Generation and Retail Corporation or the Regional Power Corporation.

If the sum for the half hourly out of balance charges for the half hours in a month is positive, then an amount equal to that sum is payable by the corporation to the user, except if the user is the Electricity Generation and Retail Corporation or the Regional Power Corporation.

For the purposes of subregulation (7), the adjusted net amount for the group of connections in respect of a user’s access agreement for a half hour is an amount equal to the energy entry amount for the group of connections for the half hour minus the energy exit amount for the group of connections for the half hour, except where —

the result is positive and is greater than the permitted tolerance for the group of connections, in which case the adjusted net amount for the group of connections is equal to that permitted tolerance; or

the result is negative and is less than zero minus that permitted tolerance, in which case the adjusted net amount for the group of connections is equal to zero minus that permitted tolerance.

The out of balance charge in respect of an access agreement for a month is determined by applying the following formula:

where —

OBC (in $) is the out of balance charge in respect of the access agreement for the month;

ANA (in kWh) is the sum of the adjusted net amounts for the group of connections in respect of the access agreement for all of the half hours falling within the month;

OBF (in ¢/kWh) is determined as follows —

if ANA is negative, then OBF is the out of balance (sell) fee set out in the fee schedule for the financial year in which the month falls;

if ANA is positive, then OBF is the out of balance (buy) fee set out in the fee schedule for the financial year in which the month falls.

If the out of balance charge for a month is negative, then the amount equal to ‑1 multiplied by that out of balance charge is payable by the user to the corporation, except if the user is the Electricity Generation and Retail Corporation or the Regional Power Corporation.

If the out of balance charge for a month is positive, then an amount equal to that out of balance charge is payable by the corporation to the user, except if the user is the Electricity Generation and Retail Corporation or the Regional Power Corporation.
