AER - Powerlink 2017-22 - Post tax revenue model - 2021-22 return on debt update - January 2021

In line with our final decision on Powerlink's electricity transmission network, we have updated Powerlink's return on debt for 2021-22. As a result of this update, the return on debt for 2021-22 is 4.52 per cent. This results in an X-factor for 2021-22 of 1.70 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.
