On 20 October 2014, Multinet applied to the Australian Energy Regulator for a change in taxes event negative pass through in relation to the repeal of the carbon pricing mechanism. Multinet proposed to vary its reference tariffs to return to customers some carbon price revenues it had over-recovered during 2013 and 2014 and to remove from its future reference tariffs carbon administration costs. Multinet updated its pass through application on 27 October 2014, to reflect the September quarter CPI.
On 12 December 2014, the AER Board approved Multinet’s proposed pass through. The AER’s considerations are set out in the AER decision paper.
