Electricity industry

The Western Australian Government owns three corporations with active roles in the electricity supply chain.

• Western Power responsible for building, maintaining and operating the electricity network within the South West Interconnected System
  • Map of the South West Interconnected System 
• Synergy – responsible for the sale of electricity and power generation within the South West Interconnected System
• Horizon Power – responsible for generation, distribution and sale of electricity in areas outside the South West Interconnected System
  • Map of Horizon Power Service Area

Privately-owned electricity generators supply almost half of the electricity in the South West electricity market and private mining, mineral processing and other operations.
