AER - Directlink transmission determination - 2018-19 return on debt update - PTRM - March 2018

In line with our final decision on Directlink’s electricity transmission network, we have updated Directlink’s return on debt for 2018–19 under NER cl 6A.6.2(l).

As a result of this update, the return on debt for 2018–19 is 4.57 per cent. This results in an X-factor for 2018–19 of –0.11 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.
