About the program
Strategic planning of our power system is crucial to making smart, informed decisions in the long-term interests of Australian energy consumers. In our role as the transmission network planner for Victoria, AEMO is undertaking the Western Victoria Renewable Integration Regulatory Investment Test for Transmission (RIT-T) to assess the technical and economic viability of increasing transmission network capacity in Western Victoria, to facilitate the efficient connection of new generation in the region. This will minimise network congestion and facilitate more efficient generation dispatch, strengthening the power system for the future by adding to the performance of the system and diversity of supply, helping to reduce the cost of electricity for consumers in the long term.
The RIT-T process is a regulatory mechanism that applies an economic cost-benefit test on new transmission electricity infrastructure proposed for the NEM. It is designed to identify the most economically efficient infrastructure investment option, so the investment meets the long-term needs of consumers.
Through this RIT-T process, AEMO, in consultation with industry, government and the community, is considering a range of options, including minor network augmentations (like installing wind monitoring or undertaking minor transmission line upgrades), major network augmentations (such as new or upgraded transmission lines, and/or the installation of equipment), and non-network options (such as battery storage and/or energy demand management) to increase transmission capacity in the Western Victoria region.
The RIT-T process is defined in the National Electricity Rules. It requires transmission network planners considering significant investment in new transmission infrastructure to publish three reports:
1. The first report, the Project Specification Consultation Report (PSCR), seeks feedback and advice on the identified need for new transmission infrastructure.
2. The second report, the Project Assessment Draft Report (PADR), identifies and seeks feedback on the preferred infrastructure investment option.
3. The third report, the Project Assessment Conclusions Report (PACR), presents the transmission planner’s recommended solution to deliver the highest net economic benefit and intended course of action.
AEMO published its PSCR for this RIT-T in April 2017.
AEMO published a Project Update on the progress of this RIT-T in July 2018.
AEMO published its PADR for this RIT-T in December 2018.
The final report in the process, the PACR, will be available mid-2019.
AEMO is committed to working with industry, government, investors and consumers to secure and shape Australia’s energy future in the long-term interests of consumers. We value your feedback and advice on this program and are committed to ongoing dialogue with our stakeholders. We will continue to provide updates as we move through this program and welcome your thoughts via our stakeholder engagement activities which will be announced on this page under our Stakeholder consultation tile in the coming months.
