In line with our final decision on Powercor's electricity distribution network, we have updated Powercor's return on debt for 2022–23. As a result of this update, the return on debt for 2022–23 is 4.37 per cent. This results in an X-factor for 2022–23 of -0.08 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.
