Energy in Perth | Compare Gas & Electricity Providers WA

Western Australia is one of the Australian states outside of the National Electricity Market, meaning the Western Australian government manages and regulates its own energy market in the state. This can cause some confusion, as there are differences not only between Western Australia energy and energy within the NEM but also between natural gas and electricity in Western Australia itself. To find out more about the energy market in Western Australia, continue to read below.

Gas Providers WA

Unlike electricity, natural gas in Western Australia is fully contestable, meaning customers can choose who their gas provider is. There are six residential gas retailers in the state, which all service the Perth Metropolitan and most populated regions. The natural gas providers in Western Australia are:

While fully contestable, the price of natural gas in Western Australia is regulated by the government in the most populated parts of the state. Gas prices in Western Australia are regulated in the Perth metropolitan area extending north to Gingin and south to Busselton, as well as in Geraldton and the surrounding areas, Carnamah, and Albany.

Outside of these areas, the price of gas is not regulated, meaning gas retailers can set their own usage rates. This does not mean all prices are the same, however, and gas providers will often offer steep pay on time or direct debit discounts.

Gas Prices in Western Australia

Gas prices in Western Australia are some of the lowest in the country, thanks to the government's regulated price caps and gas providers offering steep and generous discounts.

In Western Australia there are three regulated gas price zones in the most populated parts of the state. Below are the government-set gas prices for the regulated distribution areas, which gas providers in Western Australia then use to set their own discounts off the usage and supply charges.

Energy Distribution Zones in Western Australia

There are five energy distribution zones in Western Australia:

  • South West Interconnected System (SWIS)
  • South Region
  • North Region
  • Gascyone/Mid-West
  • North West Interconnected System

The majority of Western Australia residents live within the South West Interconnected System, which stretches from Albany and the south-west coast to as far north as Kalbarri, and inland to Kalgoorlie-Boulder.

Can I Choose My Energy Provider in Western Australia?

Unlike other parts of the country, Western Australia does electricity and gas differently. While residents of the state have the ability to choose their gas provider, though prices are regulated by the government, electricity is non-contestable for virtually all residential customers in Western Australia.

Technically, those living within the South West Interconnected System could have the ability to choose their energy provider, if they use over 50mWh per year, but considering the average residential household in Western Australia uses approximately 6mWh per year it’s safe to say that all residents of Western Australia do not have the ability to choose their electricity provider.

Unlike electricity, natural gas is fully contestable in Western Australia, which gives gas providers the ability to freely compete in the gas market. Gas prices are, however, regulated for the majority of the population.

In the unlikely event that you are unhappy with your energy provider, Western Australia has an Ombudsman who can assist you in resolving disputes with your energy supplier as well as offer advice on common energy-related topics.

Electricity Providers WA: Synergy & Horizon Power

There are two residential electricity providers in Western Australia; Synergy and Horizon Power. Those living within the SWIS network will most likely have their electricity provided to them by Synergy while Horizon Power is the only electricity provider to supply most of those living in regional and rural Western Australia outside of the SWIS.

Electricity prices in Western Australia are regulated by the government, so electricity rates don’t vary between Synergy and Horizon Power. In addition to the traditional single-rate tariff, residential customers with smart meters might be eligible for a time-of-use tariff.

Synergy is the retailer providing energy to customers living under the South West Interconnected System. As mentioned, you are only contestable if you use more than 50 MWh, which is why only a handful companies can chose their electricity provider in Perth and why the vast majority of residential customers have no other choice than to sign up for Synergy plans.

Renewable Energy in Western Australia

Historically, renewable energy in Western Australia has lagged behind other states in the country despite WA having some of the best solar and wind power resources available. In recent years however, thanks to the cost of rooftop solar PV decreasing, solar energy is becoming one of the largest electricity generator in the state.

According to the AEMO, 27% of households in Western Australia had solar PV installed on their rooftops in 2019 with over 950MW of total capacity and rooftop solar PV is predicted to reach 2,500MW by 2029. In addition, the WA Government has recently launched a $66.3 million package with a focus on renewable technologies to create jobs, reduce electricity costs, and bring Western Australia closer to its renewable energy goals.
