On 30 April 2015, we released our final decision on the revenue that TransGrid may recover from its customers over the 2015–16 to 2017-18 regulatory control period.

We also released a Fact Sheet to accompany and summarise our final decision. The purpose of this Fact Sheet is to make our decision accessible to a wide ranging consumer audience.

The AER must publish certain models with its final decision for TransGrid.

The AER commissioned a range of reports from consultants.

On 20 May 2015 the AER wrote to TransGrid setting out how it proposed to correct a small number of administrative errors in its 30 April determination. This is to ensure that the associated legal documents accurately reflect its decision.

On 3 July 2015 the AER decided to revoke its final determination and publish substitute versions of the transmission determination, overview and the attachments affected by these administrative errors.
