ACCC Reports on Energy Enquiry

The ACCC has produced a report as part of its inquiry into the prices, profits and margins in the supply of electricity in the National Electricity Market (NEM).

The report presents an analysis of electricity retailers’ billing data and the electricity prices faced by customers in Victoria, New South Wales, South Australia, and south-east Queensland up to quarter 3 2021.

These are the regions of the National Electricity Market with effective competition in retail markets. The report extends the ACCC’s analysis of retailers’ billing data, which was most recently presented in the May 2021 report.

Since the report was finalised, there has been a substantial shift in Australian energy markets. We prepared an addendum to the report to explain the drivers of the unprecedented changes, the price impacts we are seeing, and the ACCC’s role.
