Transmission, generation and storage projects in the South West REZ

Transmission projects

EnergyCo is leading the delivery of the South West REZ Network Infrastructure Project (RNIP) to enable the South West REZ to reach its full intended transfer capacity and support the connection of the 4 access rights projects.

The South West RNIP will build on the planned transmission infrastructure delivered through Humelink and Project EnergyConnect.

Together, these form the ‘access rights network’ in the REZ.

Generation and storage projects

Four renewable energy and storage projects have been granted access rights in the South West REZ. These projects have a combined generation capacity of 3.56 gigawatts, made up of wind, solar and batteries. 

These are the first access right holders in the South West REZ. They will be able to connect to the access rights network. 

South West REZ Network Infrastructure Project

The South West RNIP works will enable the delivery of the intended network capacity of 2.5 GW in the South West REZ by the end of 2029 and support the timely connection and operation of 3.56 GW of new renewable generation and storage projects by the 4 access right holders.     

In our role as Infrastructure Planner, we have assessed the network infrastructure required to support the South West REZ and recommended the South West RNIP to the Consumer Trustee for authorisation.

Transmission projects in South West REZ

EnergyCo, as Infrastructure Planner under the Electricity Infrastructure Investment Act 2020, is responsible for ensuring that the South West REZ has the network infrastructure needed to meet the REZ’s intended network capacity and connect the South West Access Rights Holders to the broader grid, delivering affordable electricity to NSW.  

EnergyCo is leading the delivery of the South West RNIP, a coordinated package of transmission, connection and system strength infrastructure. 

The South West RNIP will build on new and planned transmission projects, including Humelink and Project EnergyConnect.

Project EnergyConnect

Project EnergyConnect is a recently completed transmission interconnector linking NSW and South Australia.

For further information, visit Transgrid’s project website. 

Victoria and NSW Interconnector West

The Victoria and NSW Interconnector West (VNI West) is a proposed transmission project that may form part of the broader South West REZ transmission network, subject to further planning and approvals.

For more information on the project, visit Transgrid’s project website. 

Generation and storage projects in the South West REZ

The projects below have been granted the right to connect to the South West REZ access rights network following a competitive tender process. You can learn more about that process on the AusEnergy Services website.

These projects will connect up to 3.56 gigawatts (GW) of clean energy to the South West REZ transmission network when they are complete. They'll deliver millions of dollars of direct community and employment benefits through the South West REZ Community and Employment Benefit Program, funded through generator access fees.

The process for awarding access rights for the South West REZ

AusEnergy Services Limited (ASL), in its role as the NSW consumer trustee under the Electricity Infrastructure Roadmap, ran a competitive tender process for access rights in the South West REZ.  

Following this tender, EnergyCo awarded four renewable energy projects access rights that represent 3.56 gigawatts of wind, solar and battery generation and storage.  

The projects awarded access rights in the South West REZ were found to be the most competitive applicants against the assessed merit criteria.  

The tender was very competitive, receiving bids representing over 15 gigawatts of wind, solar and battery capacity. This was almost 4 times the generation capacity available under this tender.

What's next for access right in the South West REZ

Projects that wish to connect to new transmission projects in the South West REZ must have an access right. There are currently no plans for another competitive access rights tender.

Projects that didn’t receive access rights may still be able to connect to lines that are not part of the South West REZ access rights network, subject to approvals processes.

Assessing impacts in the South West REZ

We are working with generation and transmission project partners, NSW Government agencies and local councils to deliver the South West REZ.  

We will work with communities and key stakeholders to understand how we can ensure long-lasting benefits and minimise impacts for the community.
