AER - SA Power Networks distribution determination - 2018-19 return on debt update - PTRM - March 2018

In line with our final decision on SA Power Networks’ electricity distribution network, we have updated SA Power Networks’ return on debt for 2018–19 under NER cl  6.5.2(l).

As a result of this update, the return on debt for 2018–19 is 5.22 per cent. This results in an X-factor for 2018–19 of –0.74 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.
