What is the Transmission Revenue Reset (TRR) 2027-2032?

The Transmission Revenue Reset (TRR) is the formal process undertaken every five years with the Australian Energy Regulator (AER) to plan our transmission network expenses. The next TRR period starts on April 1, 2027. Our five-year plan, referred to as a Revenue Proposal, must be submitted to the AER by October 31, 2025. The AER will review our plan and decide our revenues, which will affect the price customers pay for electricity, as well as the types and quality of services we deliver.

Our transmission network

We are responsible for keeping the transmission network reliable and safe. Therefore, our TRR proposal will focus on the costs and revenues needed to manage non-contestable transmission projects and infrastructure in a manner that is consistent with customers' long-term interests.

Our customers, their representatives and other interested parties are encouraged to provide feedback and submissions.

As operator of the Victoria electricity transmission network, we transport electricity from large coal, gas and renewable generators across Victoria and interstate, to terminal stations that supply large customers and the distribution networks. Those networks then deliver the electricity to households and businesses.
