Appendix E - Transmission roll forward model handbook - April 2020

The AER has published its final decision on the gas financial models for distribution and transmission network service providers.

The AER extended the time to make its final decision on the gas financial models under NGR r. 75A(8). This extension became necessary because of circumstances beyond the AER’s control and unusual complexity that arose.

In May 2022, version 1 of the distribution and transmission RFMs and distribution tracking module were replaced with version 1.1 after correcting errors identified in the models. These changes are identified in the version records on the Intro sheets.
