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, TransGrid 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:
Public Interest Advocacy Centre
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, TransGrid is only able to present the overall net market benefits of each credible option in the PADR and publish this supporting document:
Market Modelling Report
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 have played a pivotal role in being able to define and include the credible options assessed in this PADR.
TransGrid will be engaging further with parties based on the outcome of this PADR to confirm the technical feasibility of the options, which is expected to involve the provision of further information and modelling from these parties. A full assessment of technical feasibility is intended to be undertaken ahead of the PACR where parties confirm they are proponents and provide the required information.
