Supplementary Project Assessment Draft Report
The Supplementary Report to the Project Assessment Draft Report (PADR), published in October 2024, offers an opportunity to assesses the potential impacts of recent developments on the preferred option identified in the PADR and allows the industry to consult on these developments ahead of the development of the final stage of the RIT-T, the PACR. This report has modelled three key sensitivities:
- Sensitivity 1: Revised retirement date of Eraring Power station;
- Sensitivity 2: Inverter-based resource forecasts within AEMO’s Final 2024 ISP, including revised timing for the New England REZ;
- Sensitivity 3: Increasing the robustness of the portfolio of system strength solution by bringing forward the commission on synchronous condensers.
Submissions on the materials contained in the Supplementary Report are now closed and will be addressed in the PACR.
Project Assessment Draft Report
The Project Assessment Draft Report (PADR), published in June 2024, provides transparency into the planning considerations for investment options to maintain adequate levels of system strength in the NSW power system, and the associated market benefits. A key purpose of this PADR, and the RIT-T more broadly, is to provide interested stakeholders the opportunity to review the analysis and assumptions, provide input to the process, and have certainty and confidence that the preferred option (or portfolio of solutions in this case) has been robustly identified as optimal.
Submissions and Expressions of Interest received in response to the PSCR were considered when preparing the PADR. The PADR includes a full quantitative analysis of the proposed options and expected net market benefit across a range of system strength portfolio options and sensitivities. We have published the PADR and associated supporting documents:
Supporting Documentation
The below documents were published by in parallel with the PADR to provide further insights into the RIT-T, procurement and contracting process and technical specifications (in addition to the documents ‘non-network system strength solutions’ section, above).
Project Specification Consultation Report
In December 2022 we published a Project Specification Consultation Report (PSCR), the first step in the RIT-T process. The PSCR details the need to meet system strength requirements in NSW and describes credible options to meet the need, including technical characteristics that would be required of a non-network option.
