This Regulatory Investment Test for Distribution (RIT-D) arises due to the need of maintaining reliability of supply in the Sunbury and Sydenham supply area whilst accommodating new customer connections, and growth in customer maximum demand.

Options Screening report

In accordance with Clause 5.17 of the NER and the AER’s RIT-D Application Guidelines November 2024, the first stage of the RIT-D process is to publish an options screening report for consultation by determining whether non-network and SAPS options are likely to form a potential credible option(s) or significant part of one or more potential credible options to address the identified need.

This options screening report:

• summarises the non-network and SAPS screening requirements and the assessment approach.
• describes the identified need JEN is aiming to address.
• describes the network options tested to date.
• describes the potential of non-network and/or SAPS options to help address the identified need.
• states the conclusion reached on potential non-network and SAPS options, and next steps.

We invite written submissions from registered participants, AEMO and interested parties, including pricing proposals from prospective non-network and SAPS providers detailing alternative solutions and demonstrating how the solutions achieve the assessment criteria presented in this report: 

• Sunbury and Sydenham Zone Substation Supply area capacity constraint OSR

All submissions and enquiries relating to this non-network options report must be lodged on or before 3 November 2025.
