What makes up your electricity bill

WHAT YOU ARE PAYING FOR IN YOUR ELECTRICITY BILL

* The cost of household electricity has risen by up to 63 per cent in the past decade, according to a preliminary Australian Competition and Consumer Commission report on pricing.

* The average residential household bill is about $1500 a year, but nearer $2000 in South Australia and Victoria.

* A huge increase in electricity network costs - driven by regulation and over-investment in poles and wires - has been the number one cause.

* The cost of networks at 48 per cent is the single biggest component of household bills.

* The wholesale cost represents 22 per cent.

* Retail and other costs make up 16 per cent, with the retail margin adding another eight per cent.

* The cost of subsidising renewable energy represents only seven per cent of the household bill.
