The energy market in Western Australia is divided into two regions, each of which has its own set of regulations. While there are a number of electricity retailers in the state, most residential customers are limited to a single provider. Electricity prices in Western Australia are regulated by the state government and gas prices are regulated in the major metropolitan areas. How much you pay for your electricity in Western Australia depends largely on where you live.
In the South West Interconnected System (SWIS), non-contestable customers are supplied by Synergy. A non-contestable customer is one that uses less than 50 megawatt-hours of electricity per year. The average household only consumes around six megawatt-hours of electricity per year, which means almost all residential customers are considered non-contestable.
Western Australian residents in the SWIS that use more than 50 megawatt-hours per year are able to choose their electricity retailer and potentially negotiate lower rates than set by the government. However, this mostly applies to businesses.
For customers outside the SWIS, Horizon Power is the only retail electricity provider.
The following energy retailers operate in Western Australia:
| Provider | ⚡ Electricity | ♨️ Gas | ☀️ Solar |
|---|---|---|---|
| Synergy | ✅ | ✅ | ✅ |
| Horizon Power | ✅ | ❌ | ✅ |
| AGL | ❌ | ✅ | ❌ |
| Kleenheat | ✅ | ✅ | ❌ |
| Alinta | ❌ | ✅ | ✅ |
| Origin Energy | ❌ | ✅ | ❌ |
| Simply Energy | ❌ | ✅ | ❌ |
| Perth Energy | ✅ | ✅ | ✅ |

If you're a contestable customer or business owner in the SWIS, switching energy providers is relatively simple. All you have to do is find a new energy provider and contact the new provider to arrange the switch.
How to switch energy providers
How is it that I used less power this bill compared to the last bill and yet my bill is double to the first. I am with Synergy.
Hi Peter,
Thanks for leaving a question on finder.
I suggest that you clarify this directly with Synergy to get a direct answer as we do not represent any of the providers on our page.
Please send me a message if you need anything else. :)
Cheers,
Joel
Why do we have to pay a supply charge of over $50.00 isn’t this amount a bit over the top.
Hi Ian,
Thanks for your question.
I would like to confirm, are you referring to usage charge? Usage charge is the additional charge that depends on how much power you actually use and it is measured in cents per kilowatt hour (c/kWh). It is sometimes called a ‘variable charge’ or ‘consumption charge’ and will vary from month to month. If your consumptions is low, the charges may be lower than $50.
You may have to directly reach out to your provider to confirm their rate for usage charges.
Cheers,

I was told that if I switch to Kleenheat because you were recommended to me or I have been referred by a kleenheat customer that I will receive an ongoing 20% discount on my bills, is that correct ?
Hi F Latham,
Thanks for your inquiry.
You maybe eligible for the 20% discount. For confirmation, It would be best to speak with Kleenheat directly you may contact them here 13 13 51 and 13 13 52

I am a resident in Perth WA. What alternatives are there for residential electricity providers, outside of Synergy? Is synergy only option? Am looking for cheaper alternatives.
Hi Tanya,
Thanks for your inquiry.
There is also 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.

Can you have pay-as-you-go system in your gas and electrical bills, like the one they have in London?
Hi Bockarie!
You can shop around with our list of energy and gas suppliers on this page.
You may also leave your information on the Enquiry Form on the same page, so that an energy broker will discuss your options.
Hope this helps.
Cheers,
Jonathan
