North West Slopes Area Supply


TransGrid is applying the Regulatory Investment Test for Transmission (RIT-T) to options for maintaining reliable supply to the North West Slopes area of northern NSW. 

In April 2021 TransGrid published a Project Specification Consultation Report (PSCR), the first step in the RIT-T process. 

The PSCR detailed the need to maintain reliable supply in the North West Slopes area and describes credible options to meet the need, including technical characteristics that would be required of a non-network option.

TransGrid invited written submissions on the material contained in the PSCR. Submissions were particularly sought on the credible options presented and from potential proponents of non-network options that could meet the technical requirements set out in the PSCR. 

Together with the PSCR, TransGrid released an Expression of Interest (EOI) to provide additional detail on the technical requirements for non-network options and seek submissions from proponents of these options. 

The next step in the RIT-T process is to publish a Project Assessment Draft Report (PADR) which will provide a full quantitative analysis and expected market benefit across a range of scenarios and sensitivities. TransGrid anticipates publication of the PADR later in 2021.
