A Comprehensive Guide to the Western Australia Energy Market

Welcome to Energy Action's guide to navigating the Western Australia (WA) energy market. As a business, understanding the energy landscape is crucial for making informed decisions about your energy consumption, contracts, and sustainability initiatives. Let's delve into the unique aspects of the WA energy market.

Understanding the WA Energy Market

Unlike the National Electricity Market (NEM) that serves Australia's east coast, WA operates under the Wholesale Electricity Market (WEM). The WEM supplies electricity to the South West of Western Australia via the South West Interconnected System (SWIS).

The SWIS covers a vast area from Albany to Kalgoorlie, extending north to Kalbarri. Outside the SWIS region, Horizon Power is responsible for generating, distributing, and selling energy for consumers.

Contestability in the WA Energy Market

In WA, the concept of 'contestability' is pivotal. A contestable customer is one who uses more than 50,000 kWh of electricity per year or spends more than $15,000 per annum. These customers, typically SMEs and large companies, have the freedom to choose their electricity retailer. They can negotiate their contracts and terms with their preferred retailer.

Non-contestable customers, on the other hand, are those who consume less than or equivalent to 50,000 kWh of electricity per annum or pay less than $15,000 per annum. These are typically residential households and small businesses, and they must stay with Synergy, the government-regulated provider.

Energy Providers in WA

There are several electricity providers in WA, but the choice only becomes available if you are a contestable customer. Some of these providers include Perth Energy, Alinta Energy, Change Energy, ERM Power, and Amanda Energy.

The Role of Renewable Energy in WA

Renewable energy is on the rise in WA, with wind power and solar energy making up a significant portion of the renewable energy in the state. The growing percentage of electricity generation through renewable energy sources helps WA move towards the zero emissions energy target.
