On 1 August 2013, the AEMC gave notice under section 107 of the National Electricity Law to extend the period of time for making a draft rule determination on the Publication of Zone Substation Data rule change request until 5 December 2013.

The time extension will enable the National Generators Forum (NGF or proponent) to investigate the quality of data currently able to be produced by distribution network service providers. The Energy Networks Association (ENA) has recently supplied sample data to the NGF for analysis. In submissions to the AEMC’s consultation paper, various stakeholders raised the issue of data quality and availability, and questioned the suitability of the data the NGF requested be published.

The AEMC will monitor the NGF and ENA’s investigations, as the quality and timeliness of outcomes may have a material impact on the draft rule determination.
