AER - Ausgrid transmission 2019–24 PTRM - 2023–24 Return on debt update - January 2023

In line with our final decision on Ausgrid's electricity distribution and transmission networks, we have updated Ausgrid's return on debt for 2023–24. As a result of this update, the return on debt for 2023–24 is 4.65 per cent. This results in an X-factor for 2023–24 of 12.93 per cent and 4.07 per cent for its distribution and transmission networks respectively. Holding other things constant, a positive X-factor implies a real revenue decrease and a negative X-factor implies a real revenue increase. The revised PTRM shows the updated X-factor.
