New England REZ Network Infrastructure Project

Key details

We're developing plans for new transmission lines, energy hubs (substations) and related infrastructure to connect new renewable energy projects in the New England region with the existing network at Muswellbrook. This is known as the New England REZ Network Infrastructure Project.

We've proposed an alignment for the project between the Bayswater Power Station and Boorolong. The proposed length is approximately 305 kilometres. It will pass through Muswellbrook Shire, Upper Hunter Shire, Tamworth Regional, Walcha Shire, Uralla Shire, Armidale regional and Singleton Local Government Areas.

Some of this infrastructure will be built outside the REZ so it can connect to the main backbone transmission network.

As infrastructure planner, we lead the development of electricity infrastructure in NSW's renewable energy zones. We're in the early stages of assessing the new infrastructure required to unlock and support the New England REZ.

Planning

Planning for the New England REZ Network Infrastructure Project is underway in line with the planning approval pathway for critical State significant infrastructure. 
Currently, our team is the developing the projects environmental impact statement (EIS), which we expect to lodge in the second half of 2026.
Our EIS assessments are based on a narrower corridor of around 250m-wide located within the broader 1 kilometre corridor. During the EIS exhibition period, communities and stakeholders will be able to make formal submissions on the merits of the project.
Construction

If the New England REZ Network Infrastructure Project is approved, we expect the preferred network operator is expected to enter into a commitment deed by late 2027.
The network operator will design, build, finance, operate, and maintain the new infrastructure. We expect contract execution and financial close in 2028, with construction to follow thereafter.
Operation

Once operational, the New England REZ Network Infrastructure Project will help deliver clean, reliable energy across NSW.
