On 30 September 2019, Ausgrid submitted a proposal to the AER to approve an amendment to its Tariff Structure Statement to include new network tariffs to apply to certain embedded network customers. On 28 February 2020, we released our decision to not approve Ausgrid's proposal to amend its Tariff Structure Statement. As a result of our decision, Ausgrid's current Tariff Structure Statement, released on 30 April 2019, will continue to apply.

Update - Return on debt for 2020-21
In line with our final decision on Ausgrid's electricity distribution and transmission networks, we have updated Ausgrid's return on debt for 2020-21. As a result of this update, the return on debt for 2020-21 is 5.37 per cent for its distribution and transmission networks. This results in an X-factor for 2020-21 of 2.67 per cent and -16.41 per cent for its distribution and transmission networks respectively. 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 PTRMs show the updated X-factor.

On 16 December 2020, the AER released its decision on a positive cost pass through application received from Ausgrid.

This results in an X-factor for 2021-22 of 2.45 per cent and -15.14 per cent for its distribution and transmission networks respectively. 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 PTRMs show the updated X-factors.
