Understand my bill

What does my power bill pay for?

When you get your energy bill, you'll see there are different parts that make up the total cost. 

In addition to the energy costs, everyone pays a small Electricity Authority Levy. This helps to fund the Electricity Authority's work to regulate the electricity industry. This is included in the section below titled 'other'.
