Find the Best Electricity and Gas in Western Australia

Information verified correct on April 28th, 2017

If you live in Western Australia then you won’t have a choice for who provides your power, it will be determined by where you live.

The energy market in Western Australia, unlike a lot of the rest of the country, has not been deregulated. The government is still the ultimate authority on energy and has not ceded power to private companies. You can’t shop around for lower prices or better deals like you can in other states, but it also takes the decision out of your hands and gives you one less thing to worry about.

What areas of Western Australia have access to electricity and gas suppliers?

The market is largely divided into the South West Interconnected System (SWIS) and other areas. Homes do not have a choice of which company they receive their energy from, which will be decided by the location of their home.

The South West Interconnected System

Home within the SWIS that consume less than 50 megawatt hours per year (which will include almost all regular sized homes) will have their power provided by Synergy. Below is a map of the SWIS and the Synergy service area.

Outside the South West Interconnected System

If you live outside the SWIS then your home will be supplied energy by Horizon Power, who specialise in rural and small community connects. The prices are regulated by the state, so don’t worry about missing out on savings. Here is a map of the Horizon Power service area.

What suppliers provide electricity and gas to Western Australia?

There are three companies currently providing energy around Western Australia.

  • Horizon Power - Owned by the Western Australian state government, Horizon Power provides energy to around 100,000 residential customers and about 10,000 businesses across the state. It is active in creating a more environmentally friendly energy network and is working to generate more power from renewables and create a more efficient state.
  • Synergy - Western Australia’s largest provider of gas and electricity, Synergy provides energy to more than one million residential, business and industrial customers in the state. It also generates its own power from a range of sources, including renewables and plays an active role in the Western Australian community.
  • Alinta - Have been supplying energy to homes and businesses in Western Australia since 1995, and currently supply over 800,000 customers around the country. At present it only retails natural gas and business energy in Western Australia, so if you’re looking for energy for your home, they will not be able to supply you.

When will the market deregulate?

Difficult to say, but probably not anytime soon – the Western Australian energy system is unlike that of the other states in Australia. With so many people spread over such vast distances, a lack of connectivity to the nationwide energy grid and infrastructure, it would seem that deregulation is still a long way off.

How much does it cost to use an energy consultant?

You won’t pay directly to work with an energy consultant, although there may be a fee somewhere along the line. Typically energy companies will pay the consultant for referring a new customer. Be sure to check with your energy consultant in regards to how they get paid and make sure that you agree with this before proceeding.
