Western Power’s Access Arrangement defines the services we provide and the revenue and policies under which we operate. The Economic Regulation Authority (ERA) reviews our Access Arrangement every five years.

To prepare our submission, we meet with customers, stakeholders and community representatives to better understand their needs and expectations and incorporate this feedback into our proposal where feasible.

The ERA delivered its final decision on our fifth Access Arrangement (AA5) on 31 March 2023 for the period July 2022 to June 2027.

Western Power would like to thank the ERA and all stakeholders who engaged with us throughout the process.

Information on our access arrangements can be found on the ERA's website.
