Compare electricity suppliers in Perth and WA

Due to the way energy is regulated in Western Australia, most residents aren't able to choose their electricity retailer. Synergy services Perth and parts of the south-east region while Horizon Power operates in the rest of the state.

However, you might be able to choose from 1 of 3 basic tariff types available:

  • Single rate tariff. Pay a daily supply charge and then for the power you use - set at one price per kWh. This means no matter what time of the day you use electricity, it all costs the same. (Synergy and Horizon)
  • Time of use tariff. Pay a daily supply charge and then a different price per kWh for your usage at peak, off-peak and super-off peak times throughout the day. (Synergy only)
  • Combined tariff. Available for those who live and run a business from the one address. Pay a daily supply charge and then for your usage at stepped rates. That means you pay a different amount per the number of units of electricity you use. (Synergy and Horizon)

There's also some notable exceptions.

You might be able to switch to regional QLD power or Northern Territory market (although they only have one retailer for electricity and gas), but where you are located will be the determining factor in this.

What electricity plan options do I have in Perth and WA?

In the southeast of the state, you'll be serviced by Synergy.

You can choose between 3 tariff types:

  • Home Plan (A1) tariff. Single rate tariff.
  • Midday Saver tariff. Time of use tariff.
  • Home Business Plan (K1) tariff. Combined/stepped usage tariff.

In regional WA your electricity provider is Horizon Power. You can choose between the following 3 plans:

  • Residential (A2) tariff. Single rate tariff.
  • Combined Use (K2) tariff. Combined/stepped usage tariff.
  • Prepaid Power. This plan lets you pay for your energy costs upfront and share costs with other householders.

Do you have to use Synergy for electricity in Perth?

If you're a resident in Western Australia, you do not have a choice in energy suppliers, meaning you will have to use Synergy.

This is because the state isn't connected to the national energy market.

Instead, Western Australia is a unique market that has its own electricity market, with its own regulations and 2 networks. These are broken down into the South West Interconnected System (SWIS) covering Albany to Kalgoorlie and a second network which is anything outside of the SWIS network.

These are further broken down into a number of regions including:

  • Kimberly region
  • Pilbara region
  • Gascoyne and MidWest Region
  • Goldfield-Esperance Region

While the vast majority of the state uses the Synergy network, there is one notable exception.

If you're a large enough business you will be able to negotiate with various suppliers.

This is based off two criteria:

  1. Spending more than $15,000 per year on electricity
  2. Use more than 50,000 kWhs

This is due to counting as contestable customers, which are available to negotiate with various providers.
