Electricity and Gas Providers in Western Australia

Residents of Western Australia can't choose their electricity providers, but they can switch gas suppliers.

The energy market in Western Australia, unlike most Australian states, has not been fully deregulated. Two companies sell most of Western Australia's domestic electricity: Synergy and Horizon Power. The two providers sell energy at the same government-regulated price and service different areas of the state.

For gas, Western Australians have two choices of provider: Alinta Energy and Kleenheat.

Who provides electricity in Western Australia?

The Western Australian electricity market is 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.

  • Synergy. The energy provider for customers within the SWIS, Synergy is Western Australia’s largest provider of gas and electricity. The company 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.
  • Horizon Power. Owned by the Western Australian state government, Horizon Power provides energy to residential customers outside the SWIS. Horizon Power 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.

Who provides gas in Western Australia?

Consumers in Western Australia have had a choice of gas provider since 2013. The two providers, Kleenheat and Alinta, cannot charge above government regulated caps, but do charge competitively below that cap, so it's worth comparing the two.

Alinta and Kleenheat both service the same areas of the state, namely the Kalgoorlie-Boulder area, Albany, Mid-West and South-West.

Will electricity prices in WA increase this year?

Electricity prices in Western Australia are set by the government and are likely to rise in 2017/18. This is due to rising wholesale electricity costs. Despite these increases, the actual cost of supplying electricity in Western Australia is still higher than the prices consumers pay. This difference is offset by government subsidies.

I have some more questions about WA energy

The Hardship Utility Grant Scheme is designed to help people in financial difficulty pay their utility bills.

Synergy and Horizon Power both have financial assistance schemes for customers struggling to pay their bills.

Concession card holders may be eligible for a range of rebates or other assistance measures.

GreenPower is a government scheme that allows consumers to purchase renewable energy through their provider. Companies selling GreenPower need accreditation by the Australian government. Check out finder's GreenPower guide here.

If you are moving out of Western Australia you will probably have to switch energy providers. In deregulated states like NSW or Victoria you will have more energy choices.

If your gas is supplied by Alinta Energy you may be able to stay with the company if moving to Victoria, NSW or South Australia.

A cooling-off period is the time during which a customer can cancel an energy contract without any fee or penalty. In most cases the cooling-off period is 10 days.

No lock-in contracts allow you to switch providers freely without incurring a penalty or fee.
