Regulatory investment test for transmission (RIT-T) and Submissions

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, all 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.

Marinus Link published its initial Project Specification Consultation Report (PSCR) as part of the RIT-T process in July 2018. This report and the feedback it has received is available below.

TasNetworks has now completed the next step of the RIT-T process, with the publication of the Project Marinus Project Draft Assessment Report (PADR). The PADR takes into account feedback from submissions received during the consultation period following the PSCR’s release.

TasNetworks will be receiving feedback on the PADR over the coming months as part of the RIT-T consultation process, including briefings in Melbourne, Sydney and Hobart in early 2020.

RIT-T and supporting documents

Subsequent to publishing the PADR, additional data files are available which contain detailed information relating to PADR modelling assumptions and results. These files are available here (ZIP file 12MB).
