AER - TasNetworks transmission - Post-tax revenue model - 2023–24 return on debt update - March 2023

In line with our final decision on TasNetworks' electricity distribution and transmission networks, we have updated TasNetworks' return on debt for 2023–24. As a result of this update, the return on debt for 2023–24 is 4.43 per cent and 4.47 per cent for its distribution and transmission networks respectively. This results in an X-factor for 2023–24 of -1.08 per cent and 1.72 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.
