Regulatory investment test process

The diagram below outlines the process of regulatory investment tests for distribution and transmission investments.

The RIT-D process applies to the distribution projects with the most expensive viable option cost more than $6 million, while the RIT-T process applies to the transmission projects with the most expensive viable option cost more than $6 million. You can find out more about Ausgrid's RIT-D projects here.

For other network projects which are not subject to the RIT-D process but undergo a similar simplified process of investigation can be viewed here.
