49  Energy storage system maximum eligible amount

 (1) The maximum eligible amount for an energy storage system for the time period, MAXEAt, in megawatt hours, is calculated as follows:

Start formula MAXEA start subscript t end subscript equals open square bracket TLED start subscript t end subscript times open parentheses one minus AF close parentheses close square bracket minus TL start subscript t end subscript end formula

TLEDt is the total amount of electricity in megawatt hours dispatched by the energy storage system in the time period t.

AF is the auxiliary factor calculated in accordance with subsection (2).

TLt are the transmission losses for the time period t calculated in accordance with subsection (3).

 (2) For subsection (1), the auxiliary factor, AF, is calculated as follows:

Start formula AF equals start fraction AUX over TD end fraction end formula

AUX is the auxiliary loss for the energy storage system in megawatt hours for:

 (a) if the time period, t, is an hour or a calendar day—the calendar month in which the time period is located; or

TD is the total amount of electricity dispatched by the energy storage system in megawatt hours for:

 (a) if the time period, t, is an hour or a calendar day—the calendar month in which the time period is located; or

 (3) For subsection (1), the transmission losses for the time period, TLt, in megawatt hours are either:

 (a) if an MLF is not determined for the energy storage system—nil; or

 (b) in any other case—calculated as follows:

Start formula TL start subscript t end subscript equals DLED start subscript t end subscript times open parentheses one minus MLF close parentheses end formula

DLEDt is the amount of electricity dispatched from the energy storage system to the network in the time period t in megawatt hours.

​MLF is the marginal loss factor, to allow for the amount of electricity losses in transmission networks, as determined by the AEMO.

 (4) The time period t, for this section must be either:

 (a) an hour; or

 (b) a time period prescribed for section 91(2)(b) of the Act.

Note: The time periods prescribed are a calendar day, calendar month and calendar year (see section 46).
