AER - AusNet Services 2017-22 - Post tax revenue model - 2020-21 return on debt update - September 2019

In line with our final decision on AusNet Services' electricity transmission network, we have updated AusNet Services' return on debt for 2020-21.

As a result of this update, the return on debt for 2020-21 is 4.78 per cent. This results in an X-factor for 2020-21 of 1.64 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.
