Regulatory Investment Tests

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 widen the scope of the RIT-T to include replacement projects. 

TransGrid has a small number of projects that are expected to become committed during the transitional period 18 September 2017 to 30 January 2018 and will therefore be excluded from the RIT-T process.  Once the committed project criteria are fulfilled any such projects will be published on the TransGrid website in compliance with the National Electricity Rules requirements.

Projects which have fulfilled the committed project criteria since 18 September 2017 are listed in the table below.
