AER - TransGrid transmission determination - 2016-17 return on debt update - PTRM - June 2016

In line with our final decision on TransGrid’s electricity transmission network, we have updated TransGrid’s return on debt for 2016–17 under NER cl 6A.6.2(l).

As a result of this update, the return on debt for 2016–17 is 6.38 per cent. This results in an X-factor for 2016–17 of 3.70 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.
