In line with our final decision on TasNetworks’ electricity transmission network, we have updated TasNetworks’ 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 5.82 per cent. This results in an X-factor for 2016–17 of 2.31 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.
