TransGrid is required to undertake the Regulatory Investment Test for Transmission (RIT-T) for regulated revenue investments.
From 18 September 2017, changes to the National Electricity Rules widened the scope of the RIT-T to include replacement projects.
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.
TransGrid is applying the RIT-T to the projects listed in the table below.
Submissions are welcome on the current RIT-T projects by the applicable consultation closing date.
TransGrid has a small number of projects that were committed during the transitional period, 18 September 2017 to 30 January 2018. These projects are excluded from the RIT-T process and are listed in the table below.
