Reliability and Reserve Emergency Trader (RERT)
When an event occurs in New South Wales and Victoria, AEMO may request generators to increase supply as well as ask large commercial users to significantly reduce load or shut down. In return, AEMO financially compensates those users. It is that cost that is then passed back to retailers, like Origin, who then pass the cost to customers who had consumed electricity in that region, at that time.
Why are you charged RERT?
RERT is calculated based on purchased load by energy retailers, then passed through to consumers based on their MWh consumption. Charges are received by the retailers in line with AEMO’s calendar which operates in arrears.
How is the RERT charge calculated?
RERT has two components:
1. Capacity or fixed charge
This represents payment to contracted participants to ensure they are available should AEMO deem it necessary to stabilise the power system.
2. Activation or variable charge
This charge applies when the service is activated. All events are listed on the AEMO website: RERT Reporting.
