Regulatory Investment Test - Transmission (RIT-T)

 

AusNet Services, in its capacity as a transmission network service provider (TNSP), is responsible for operating, maintaining and replacing the shared transmission network, and for providing connection services.

From 18 September 2017, changes to the National Electricity Rules widened the scope of the RIT-T to include replacement projects. AusNet Services is required to undertake the Regulatory Investment Test for Transmission (RIT-T) for replacement projects exceeding $6 million. 

The purpose of the RIT-T, as set out at clause 5.16 of the National Electricity Rules, 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 market.

AusNet Services is applying the RIT-T to the projects listed in the table below.

The regulatory investment test for transmission (RIT-T) is a cost benefit analysis overseen by the Australian Energy Regulator (AER). It assesses the economic and technical impact of, and preferred timing for major network investments in the national energy market (NEM). The RIT-T process ensures regulated transmission investment decisions are in the long term interests of customers.
