The Australian Energy Market Commission (AEMC) has extended the period of time for making the draft determination on the Material change in network infrastructure project costs rule change request. It will now be delivered by 7 July 2022.

This further extension of time allows the Commission to align the rule change request with stage 3 of the Transmission planning and investment review (TPIR), which includes an examination of the economic assessment framework.  

The Commission made this decision to progress the rule change request in parallel with the TPIR and any potential changes to the economic assessment framework.

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.
