RIT-T for replacement
In addition to the consultation requirements for augmentation expenditure, the RIT-T has been extended to apply to replacement expenditure planning from 18 September 2017.
Powerlink has a 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 Powerlink’s website in compliance with the National Electricity Rules requirements.
Projects which have fulfilled the committed project criteria since 18 September 2017 are listed below.
