AER - Powerlink 2017-22 - Post tax revenue model - 2018-19 return on debt update - March 2018

In line with our final decision on Powerlink’s electricity transmission network, we have updated Powerlink’s return on debt for 2018–19 under NER cl 6A.6.2(l). As a result of this update, the return on debt for 2018–19 is 5.04 per cent. This results in an X-factor for 2018–19 of 0.47 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.
