On 3 May 2012, the Australian Competition Tribunal released its decision on the appeal by SP AusNet against the AER's determination on smart meter budget and forecast charges for the period 2012 to 2015.
The Tribunal found that the AER had not erred in reaching this conclusion. However, the Tribunal set aside the AER's decision and requires the AER to amend its decision by considering the costs and delays if SP AusNet were to change to a different technology.
The AER's amended decision must also include additional expenditure relating to foreign exchange contracts and project management costs. Australian Competition Tribunal decision
On 5 June 2012, SP AusNet provided a submission reconsidering its choice of communications technology, following a request from the AER.
