Regulated Revenue Determination

Transmission Revenue Reset Process

As a regulated business, TransGrid is required to lodge a Revenue Proposal with the Australian Energy Regulator (AER) by 31 January 2022. This sets out our proposed revenues and investment plans for the five-year regulatory period commencing 1 July 2023. 

The process for setting revenue is referred to as the Transmission Revenue Reset. The next five-year regulatory period for electricity transmission runs from 1 July 2023 to 30 June 2028.
