AER - ElectraNet 2018-23 - Post-tax revenue model - 2020-21 return on debt update (incl main grid system strength contingent project) - March 2020

In line with our final decision on ElectraNet's electricity transmission network, we have updated ElectraNet's return on debt for 2020-21. As a result of this update, the return on debt for 2020-21 is 4.35 per cent. This results in an X-factor for 2020-21 of -0.67 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.
