In November 2018, TransGrid and Powerlink published the Regulatory Investment Test for Transmission (RIT-T) Project Specification Consultation Report (PSCR)

 

TransGrid, together with Powerlink, have now published an RIT-T Project Assessment Draft Report (PADR) on expanding Queensland to New South Wales transmission transfer capacity.

 

The report details the preferred option (1A):

  • Uprating the Liddell to Tamworth transmission lines

  • Installing new dynamic reactive support at Tamworth and Dumaresq

  • Installing new shunt capacitor banks at Tamworth, Dumaresq and Armidale

 

This option is expected to:

  • deliver net benefits of approximately $200 million over the 25 year assessment period (in present value terms);

  • reduce the need for new generation and large-scale storage in New South Wales to meet demand following Liddell Power Station’s forecast retirement over 2022 and 2023;

  • lower the aggregate generator fuel costs required to meet demand in the National Electricity Market (NEM) going forward;

  • minimise capital costs associated with enabling greater integration of renewables in the NEM;

  • generate sufficient benefits solely by avoiding construction of what would otherwise be built in Liddell’s place to recover the project capital costs.

The project is expected to cost $175 million with the first stage complete by 2020
