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.
