What is a demand tariff?
A demand tariff is a pricing structure that includes a "demand charge" for your use of the electricity network.
A demand charge on your electricity bill is calculated based on your household’s demand on the network (i.e. the poles and wires) i.e how much energy you use during a specified time period.
If you are on a demand pricing plan, you'll need to know:
- When the peak demand window applies; and,
- How the demand charge is calculated.
How is the demand charge calculated?
We take the one day of the month when the highest 30-minute period of consumption occurs during that day’s peak demand window. It’s measured in kilowatts and then multiplied by the total number of days in that month.
Demand charge = Max demand during demand window (kW) x charge ($) x days in billing period (day)
For example, if your maximum energy usage during the demand window (4pm and 9pm) is 0.676 kWh (which is for example recorded at 6 - 6:30pm) then to work out the maximum demand, you take that maximum energy used during the 30 minute window and multiply that by 2 to convert it from kWh to kW.
Max demand = 0.676kWh x 2 = 1.352 kW
Therefore, the demand charge for the month of May will be:
Demand charge = 1.352kW x $0.0834317 x 31 days = $3.50
Is there a reference price to compare against?
No, demand tariffs do not have reference prices.
