Project overview




On 20 August 2018, the Treasurer directed the ACCC to hold a public inquiry into the prices, profits and margins in the supply of electricity in the national electricity market.

The terms of reference required a first report by 31 March 2019 and then every 6 months until the end of the inquiry on 31 August 2025.

The ACCC will also provide information to the market as appropriate.

Scope of inquiry

The inquiry will monitor and consider matters including, but not limited to:

  • electricity prices faced by customers in the national electricity market, including both the level and the spread of price offers
  • analysing how wholesale prices are influencing retail prices and whether any wholesale cost savings are being passed through to retail customers
  • wholesale market prices including the contributing factors, such as input costs, bidding behaviour and any other relevant factors
  • the profits being made by electricity generators and retailers and the factors that have contributed to these
  • contract market liquidity, including assessing whether vertically integrated electricity suppliers are restricting competition and new entry
  • the effect of policy changes resulting from recommendations made by the ACCC in its Retail Electricity Pricing Inquiry report of July 2018.

Where appropriate, the inquiry will make recommendations to government(s) to take any proportional and targeted action considered necessary to remedy any failure by market participants, or the market as a whole, to deliver competitive and efficient electricity prices for customers.



Enquiries can be made by email to or you can contact the ACCC.
