Appendix G - List of changes from previous roll forward models - April 2020

The AER has published its final decision on the amendments to the roll forward models for distribution and transmission network service providers.

The AER extended the time to make its final decision on the amended roll forward models under NER cll. 6.16(g) and 6A.20(g). This extension became necessary because of circumstances beyond the AER’s control and unusual complexity that arose.

In May 2022, version 4 of the transmission RFM was replaced with version 4.1 and version 3 of the distribution RFM was replaced with version 3.1 after correcting errors identified in the models. These change are identified in the version records on the Intro sheets.
