Description:	Proportion of charging load that can be deferred

Charging Station Deferrable Load is a multi-band property that works in combination with Deferment Period. It sets the proportion of charging load that can be deferred in the given band. Deferring load can reduce the cost of charging by shifting some or all of the charging load into future periods with a lower electric price.

Deferrable load represents potential deviations from prescribed charging profiles which are defined prior to simulation commencement. Deferment should therefore be used in conjunction with simple Vehicle models (which define Fixed Load). Non-simple (i.e. detailed) vehicle models allow charging to occur at times and quantities that minimise total system cost: deferment is redundant when charging is cooptimised in this way. Warning 3245 will occur if deferment is being used in conjunction with detailed vehicle models. See Vehicle for a comparison of simple and detailed vehicle models.

Table 1: Deferrable Load and Deferment Period Example
Child Object	Property	Value	Data File	Units	Band
Supercharger	Deferrable Load	90		%	1
Supercharger	Deferrable Load	75		%	2
Supercharger	Deferrable Load	60		%	3
Supercharger	Deferrable Load	45		%	4
Supercharger	Deferrable Load	30		%	5
Supercharger	Deferrable Load	15		%	6
Supercharger	Deferment Period	1		h	1
Supercharger	Deferment Period	2		h	2
Supercharger	Deferment Period	3		h	3
Supercharger	Deferment Period	4		h	4
Supercharger	Deferment Period	5		h	5
Supercharger	Deferment Period	6		h	6

In the above example 90% of the charging load can be deferred by one hour, which includes the 75% that can be deferred up to two hours, etc.
