ElectraNet has published a Project Assessment Draft Report (PADR) for the South Australian Energy Transformation Regulatory Investment Test for Transmission (RIT-T), as required by the National Electricity Rules clause 5.16.
The PADR is the second stage of a RIT-T process, and describes the identified need for investment, the network and non-network options that are being considered to address the identified need, and specific categories of market benefit and their applicability to this RIT-T.
ElectraNet has investigated interconnector and network support options aimed at reducing the cost of providing secure and reliable electricity to South Australia in the near term, while facilitating the longer-term transition of the energy sector across the National Energy Market (NEM) to low emission energy sources.
Our RIT-T assessment shows that of all options considered a new 330 kV interconnector between mid-north South Australia and Wagga Wagga in New South Wales, via Buronga, is expected to deliver the highest net market benefits. This finding is robust across a wide range of future scenarios and sensitivity tests.
ElectraNet welcomes written submissions on the information presented in this PADR. Submissions are due by 10 August 2018.
Submissions should be marked “South Australian Energy Transformation PADR feedback” and emailed to consultation@electranet.com.au.
The next formal stage of this RIT-T involves publication of a Project Assessment Conclusions Report (PACR). We currently anticipate that a PACR will be released by November 2018.
