The Australian Energy Regulator (AER) has published performance data for electricity transmission network service providers (TNSPs). The data reflects the key components of the AER's regulatory determinations as well as other performance metrics. The data is presented for each TNSP and aggregated to report a transmission total for some data. The period covered is 2006 to 2018.
The data series are provided to facilitate general stakeholder engagement in the AER's regulatory processes. The data is subject to revisions, arising from changes from improved data collation, or regulatory updates that apply from time to time. Information to aid interpretation of the data is available with the transmission businesses RIN responses, AER Guidelines and reviews, and explanatory material associated with our models and data collections - available on the AER website.
