Wholesale electricity prices above $5000 per MWh in South Australia on 22 January 2021

The Australian Energy Regulator (AER) monitors and reports on wholesale electricity markets and is required to report on events that result in wholesale electricity spot prices exceeding $5000 per megawatt (MWh) hour and average frequency control ancillary service (FCAS) prices above $5000 per MW over consecutive trading intervals.

Most customers are not directly exposed to wholesale electricity prices. Energy retailers are the main purchasers in the wholesale electricity market. Retailers bundle electricity with network services for sale to their residential, commercial and industrial customers. Generators and retailers can manage their exposure to price variations in the wholesale market by entering hedge contracts that lock in firm prices for the electricity they intend to produce or buy.

On 22 January 2021, the wholesale electricity price in South Australia went above $5000 per MWh for the 4 am trading interval. We will publish a report into this high price by mid-March 2021.
