June 2022 market events report

Compliance bulletin
Release date: 
15 December 2022


The AER has released its report into market events that led to the suspension of the national electricity spot price market in June 2022. The AER has completed an investigation into the behaviour of generators after it had received reports from stakeholders that generators were withdrawing capacity, causing the Australian Energy Market Operator (AEMO) to issue urgent directions to get supply into the market to mitigate the risk of blackouts.

The report outlines the background to the investigation including market conditions, investigation findings and sets out some reform options for consideration.
