AusNet is initiating this Regulatory Investment Test for Distribution (RIT-D) to investigate and evaluate options to address the constraints in the MWTS South sub-transmission network which are restricting new renewable generation connections. Publication of this Options Screening Report (OSR) represents the first step in the RIT-D process in accordance with clause 5.17 of the National Electricity Rules (NER) and section 4.2 of the RIT-D Application Guidelines.
Originally AusNet’s sub-transmission network was planned to supply the electricity demand, rather than accommodate renewable generation. The Morwell South sub-transmission network was planned, built, and maintained to meet the demand in that area and is not strong enough to connect significant additional renewable generation.
The purpose of the RIT-D is to identify the credible option that maximises the present value of net economic benefit to all those who produce, consume and transport electricity in the National Electricity Market (NEM).
AusNet welcomes written submissions on the credible options presented in this OSR and invites proposals from proponents of potential non-network options. Submissions should be emailed to email@example.com on or before 15 April 2024. In the subject field, please reference ‘RIT-D OSR CE Morwell South.’
