The draft determination on the Material change in network infrastructure project costs rule change request will be delivered by 28 April 2022.

This extension of time allows the Commission to consider a range of complex issues and to progress the rule change request in parallel with the Transmission planning and investment review (TPIR), which is examining closely related matters. The new date for this rule change allows the draft determination to be published alongside the TPIR draft report. 

A public forum discussing both the TPIR and this rule change request will be held on 13 December 2021. Stakeholders are invited to register here. 

The rule change request proposes to include cost increase thresholds in the National Electricity Rules so that, if the estimated cost of a project materially increases following completion of the regulatory investment test (RIT), the proponent must reopen the RIT unless the Australian Energy Regulator determines otherwise.

The TPIR is examining the regulatory frameworks for transmission planning and investment with a view to facilitating the timely and efficient delivery of major transmission projects.
