In Queensland, electricity prices are regulated by the Queensland Competition Authority (QCA).
Electricity bills are based on a consumption charge (cents/kWh) for the amount of electricity used, plus a daily service fee of cents per day. These should be listed on your bill.
The type of contract you're on may also determine costs.
Tariff 11 is the most common tariff for residential customers but other options are available.
This guide explains electricity prices and the tariff structures, and how your bill is determined.
The QCA has released its final determination for regulated retail electricity prices for 2015–16. Many tariff prices will stay the same or decrease from 1 July 2015.
The final determination is available on the QCA website.
