Who owns Australia’s coal-burning power stations?

During 2019, coal-burning power stations was responsible for nearly 60% of Australia’s electricity generation.X But who owns and runs these power stations? What are these companies responsible for? What does each company contribute to Australia’s share of greenhouse gas emissions? And which companies are the highest polluters?

The table below outlines key information about the companies that own coal-burning power stations within the National Electricity Market (NEM), and Western Australia’s equivalent (the SWIS).

These companies have varied decision-makers. Every power station’s situation is different. Some are owned by companies that just generate electricity and then sell it to retailers; some by companies that both generate electricity and retail it to consumers. Some of these companies are publicly-owned by state governments and some are private corporations (either Australian or foreign-owned). Some power stations also have several co-owners. Therefore, the decision makers with control over each station’s impacts and how long they continue to operate vary considerably.
