AER - Ausgrid distribution 2019-24 - Post-tax revenue model - 2020-21 Return on debt update - January 2020

In line with our final decision on Ausgrid's electricity distribution and transmission networks, we have updated Ausgrid's return on debt for 2020-21. As a result of this update, the return on debt for 2020-21 is 5.37 per cent for its distribution and transmission networks. This results in an X-factor for 2020-21 of 2.67 per cent and -16.41 per cent for its distribution and transmission networks respectively. 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 PTRMs show the updated X-factor.
