AER - Power and Water 2019-24 - Post-tax revenue model - 2021-22 return on debt update - March 2021

In line with our final decision on Power and Water Corporation's electricity transmission network, we have updated Power and Water Corporation's return on debt for 2021–22. As a result of this update, the return on debt for 2021–22 is 3.93 per cent. This results in an X-factor for 2021–22 of -0.59 per cent. 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.
