Electricity transmission code review 2018 - draft decision - Archived

26 Apr 2018


The Commission is undertaking a review of the Electricity Transmission Code and is publicly consulting on proposed drafting amendments to the Code.

The Code applies primarily to ElectraNet Pty Ltd, South Australia’s major electricity transmission network business. The Commission last reviewed the Code in 2016 and set the transmission network planning and reliability standards to apply from 1 July 2018, the start of the next five-year regulatory period for ElectraNet. 

However, matters have arisen since that previous review that have led the Commission to commence a targeted review of the Code. Specifically, the review aims to address the following issues:

Clarification (but not substantive change) of the reliability standards that apply to transmission exit points where there are two supply sources and the back-up source is non-firm (the ‘category 3’ exit points) 
The application of reliability standards to customers that receive negotiated transmission services, such as grid-scale batteries
The suspension of the restoration targets during times where it is unsafe for employees or contractors of ElectraNet to restore transmission services, or where it is otherwise not possible to restore transmission services due to circumstances outside ElectraNet’s control
The removal of redundant obligations, following recent legislative changes.
Other minor clarifications, to improve readability of the Code. 

The Commission invites written submissions on this paper by 2 June 2018 .
