AER - AusNet Services 2017-22 - Post tax revenue model - 2019-20 return on debt update - January 2019

In line with our final decision on AusNet Services' electricity transmission network, we have updated AusNet Services' return on debt for 2019-20 under NER cl. 6A.6.2(l).

As a result of this update, the return on debt for 2019-20 is 4.93 per cent. This results in an X-factor for 2019-20 of 1.18 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.
