How demand pricing is calculated for home energy plans

For ACT customers, when you move to a home demand pricing plan, your bill shows a peak demand charge. This peak demand charge is based on the maximum demand your household places on the network in a 30 minute interval, during the peak demand window of 5–8pm AEST daily. For businesses this is between 7am – 5pm on business days.

The amount is calculated as follows:

Your maximum demand (calculated within a 30 minute interval and measured in kilowatt hours) and converted to kW

x

Demand charge rate in kW (rate set out in ActewAGL’s schedule of charges)

x

The number of days in that month

= monthly demand charge

For example

Let’s say your household uses a number of appliances one night between 6pm and 6:30pm which consume 4 kilowatt hours (kWh) of electricity, which is equivalent to 8kW over an hour.

If this 30 minute interval is the maximum peak usage in a calendar month between 5 - 8pm, it ends up being your maximum demand for that month.

So, your demand charge for that month will be:

Maximum demand: 8kW

x

Demand charge rate: $0.16816 (inc GST)*

x

Number of days in the month: 30 days

= Demand charge: $40.36

 

The maximum demand resets each calendar month. For quarterly bills, you’ll find three demand charges, one for each calendar month.
