Market-leading analysis

Monitoring the performance of gas and electricity transmission and distribution networks that we regulate helps us build knowledge and trust in Australia’s energy system.

We collect and publish data from network businesses that allow us to undertake our regulatory functions, including monitoring outcomes against revenue determinations, developing performance reports and preparing for future determinations.

Regulatory Information Notices (RINs)

We issue annual Regulatory Information Notices (RINs) that enable us to collect and monitor information from regulated businesses. We publish non-confidential information from their RIN responses to increase the transparency and accountability of network performance to stakeholders.

To request further information about supporting the data in annual RIN responses, please email AERInquiryataer [dot] gov [dot] au (AERInquiry[at]aer[dot]gov[dot]au).
