In November 2019, TransGrid published the Project Specification Consultation Report (PSCR). The PSCR detailed the need to maintain reliable supply to Broken Hill and describes credible options to meet the need, including technical characteristics of a non-network option.
Maintaining a reliable supply to Broken Hill Project Specification Consultation Report (PSCR)
In response to the PSCR, we received submissions from five parties. Four of these parties requested confidentiality. The fifth submission was from the Public Interest Advocacy Centre and is available below:

Comments and points raised in all submissions were considered when preparing the Project Assessment Draft Report (PADR). The PADR is a full quantitative analysis of the proposed options and expected market benefit across a range of scenarios and sensitivities.
Maintaining reliable supply to Broken Hill Project Assessment Draft Report (PADR)
Due to the confidentiality requested by proponents of solutions, we are only able to present the overall net market benefits of each credible option in the PADR and publish this supporting document:
Market Modelling Report
In response to the PADR, we received submissions from eight parties. Submissions approved for publication are below:
Prior to, as well as after, receiving submissions, TransGrid held a number of bilateral meetings with submitters to enable greater understanding of the RIT-T assessment, the reliability requirements at Broken Hill and how the proposed solutions are expected to be able to assist with meeting the identified need. These discussions played a pivotal role in being able to define and include the credible options assessed in this PADR.
TransGrid engaged further with parties based on the outcome of the PADR to confirm the technical feasibility of the options, which involved the provision of further information and modelling from these parties. A full assessment of technical feasibility will be undertaken ahead of the PACR where parties confirm they are proponents and provide the required information.
Having sought advice from the AER, we will issue a revised PADR incorporating changes outlined in the AER’s updated RIT-T Application Guidelines. The revised PADR is expected to be published in Q3 2021. A six-week consultation period will follow, during which we welcome submissions on the revised PADR.
