The Big three dominate Australian Electricity Market


  • Temporary shutdown of businesses due to COVID-19 in 2020 significantly impacted the energy demand
  • The average annual price hit prices last seen in 2015
  • The big three- Energy Australia, AGL, and Origin Energy cater to the bulk of the electricity market

The overall energy demand in Australia tumbled in 2020 due to significant drop in commercial load associated with the temporary shutdown of businesses due to COVID-19. On the brighter side, the country's energy market is seeing a transition from a fossil fuel-driven source towards renewable power.

In 2020, more than 3,700MW of mega-scale wind and solar generation capacity have entered the National Energy Market (NEM), majorly in NSW and Victoria contributing more than 19% of the country's total electricity generation. At the same time, fossil fuel-driven electricity has contributed more than 70% of the total electricity generation in the country.

Electricity prices tumbled by around 23-58% in all the regions of the country in 2020, relative to 2019 average levels. The average annual price was below AU$70 per MWh in all regions of the country, the lowest since 2015. However, prices increased significantly in the first half of 2021 with numerous plants running offline due to maintenance and reduced availability of coal-fired power plants amid country's goal to attain carbon neutrality in coming decades.

The electricity demand has also increased due to the rise in demand associated with winter heating and a significant fall in the output of renewable energy amid bad weather conditions in the country.

Bottom Line

There are many electricity providers in Australia that offer several plans in different cities of NSW, VIC, QLD, and SA. Various companies are offering ethically sourced energy while few of them also provide this as an option to the customers to choose from.

As per the Australian Energy Regulator Retail Energy Market Performance Update for Quarter 2, 2020-21, “big three” have a 79.1% market share in NSW, 54% in VIC, 49.8% in QLD, and 72% in South Australia.

Big three are legacy players in this field with a lot of exposure and experience. However, several new players have now entered the market and offering electricity at competitive prices.
