AER - TasNetworks transmission - Post-tax revenue model - 2021-22 return on debt update - March 2021

In line with our final decision on TasNetworks' electricity distribution and transmission networks, we have updated TasNetworks' return on debt for 2021–22. As a result of this update, the return on debt for 2021–22 is 4.41 per cent and 4.65 per cent for distribution and transmission respectively. This results in an X-factor for 2021–22 of -1.09 per cent and 1.70 per cent for distribution and transmission 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 PTRMs shows the updated X-factors.
