What makes up your electricity bill?

An electricity bill is made up of various costs of delivering electricity to your home or business. In the graph below, you can see wholesale and network costs make up the majority of your bill. These percentages are based on data provided by the Victorian Essential Services Commission. These are an example only and won't reflect individual circumstances which can be impacted by things like where you live and how much power you use.

Bill Breakdown

Percentage figures are rounded to the closest whole number. Source: 1

Network
Network 37%

Electricity has to get from where it’s produced to your place. And this network cost covers the 'poles and wires' to do this. Network costs have grown from 31% to 37% in the past year.

Wholesale
Wholesale 30%

This is what retailers pay for the energy they sell and factors in what it costs to generate. As a proportion of an average bill, wholesale prices have reduced from 36% to 30% in the past year.

Environmental
Environmental 7%

These are charges that cover costs retailers incur to comply with government programs that promote renewable energy and energy efficiency.

Retail costs
Retail operating costs 12%

Basically, the cost of all the things needed to run a business; call centres, customer care, marketing, billing, wages for employees who keep everything running smoothly.

Retail margin
Retail margin 5%

This is the profit retailers make. Any profit Momentum makes is either reinvested back into our business or goes to our parent company, Hydro Tasmania, Australia’s largest generator of renewable energy.

GST
GST - about 9%

Yep, this is pretty self-explanatory. The Goods and Services Tax is added to most of what you buy in Australia. Certain basics are excluded. And while you might expect this to be 10%, when you add 10% to the invoice this actually makes it 9% of the overall bill.


Where is electricity sourced from?

According to annual data for the National Electricity Market (NEM), most of Australia's electricity is produced from burning black (46%) and brown coal (16%). Renewables contribute most of the remaining energy supply, with solar (9%), wind (16%), and hydro (7%) being the key sources. Coal-fired generation continues to decline, while renewables are increasing each year.

What makes up your gas bill?

Your gas bill is made up of the various costs of delivering gas to your home or business. These costs include:

Wholesale
Wholesale

This is the cost to the retailer of purchasing gas from suppliers. It is influenced by market factors such as supply and demand, as well as production costs like exploration, extraction, processing and storage.

Network
Network

Gas has to get from where it’s produced or stored to your place. This happens via big transmission pipelines, to bring it to your local area. From there it travels through distribution networks that transport it right to your home or business.

Environmental

Where is Australia's gas sourced from?

Natural gas is the third highest energy source in Australia (after oil and coal). It is used by power stations for electricity generation, factories for manufacturing, and homes for heating and cooking. It is a non-renewable source that emits around half the emissions of coal when used to generate electricity.

Gas used to come from large remote reservoirs, such as the Moomba and Bass Strait gas fields. More recently, coal seam gas comes from Queensland with untapped reserves in NSW and Victoria.

Once gas is sourced from gas fields (oil and gas wells or coal seam wells) it is processed to specification. This includes adding the odour for safety reasons, and compressing the gas for transport. Source: 4
