The Transmission Planning Review (the Review) will consider transmission planning arrangements in NSW and make recommendations for reform.
The Review commenced in February 2025 and is set to conclude in September 2025.
Purpose of the Review
The Review was a recommendation of Electricity Supply and Reliability Check Up report (the Check Up), which identified reform and further work needed to deliver the NSW Electricity Infrastructure Roadmap. The Roadmap coordinates investment in new transmission, renewable generation, storage and firming infrastructure to ensure NSW has an electricity system that provides affordable, clean and reliable energy for everyone.
The Check Up recommended the Review advise on the best way to coordinate transmission planning between:

The Minister has authorised the Review, which will be conducted in line with the Terms of Reference.
The Review team will lead multiple rounds of stakeholder consultation, including through submissions to an Interim Report, expected to be made public in June and July 2025. An initial Consultation Paper has been published alongside the Terms of Reference to guide early targeted stakeholder engagement.
