Location

Piambong, NSW

The Piambong Wind Farm development is located approximately about 20 kilometres north-west of Mudgee and about 20 kilometres south-west of Gulgong, in Central West New South Wales.

The proposed Project area covers approximately 8,800 hectares. Only a small fraction of this is expected to be disturbed during construction. The Project will be largely compatible with existing agricultural practices.

The Project will be constructed on freehold land within the Mid-Western Regional Local Government Area. The land to be used for the Project will be secured under lease agreements with local landholders.

What is a Renewable Energy Zone (REZ) ?

Renewable Energy Zones (REZs) are modern-day power stations. They combine renewable energy generation such as wind and solar, storage such as batteries, and high-voltage poles and wires to deliver energy to the homes, businesses and industries that need it. By connecting multiple generators and storage in the same location, REZs capitalise on economies of scale to deliver affordable, reliable and clean electricity for NSW.

Central West Orana Renewable Energy Zone

The Piambong Wind Farm is located within the Central West Orana Renewable Energy Zone (CWO REZ), which was formally declared on 5 November 2021. The CWO REZ will initially provide  4.5 GW network capacity, which will allow for 7.7 GW of projects to connect to the transmission network. The capacity is expected to increase to 6 GW by 2038, subject to further assessment and consultation.

Ten renewable energy projects have been granted access rights in the CWO REZ.

Construction of the new high voltage electricity transmission network, energy hubs and switching stations started in June 2025, with energisation expected in 2028. EnergyCo has appointed ACEREZ – a partnership of ACCIONA, COBRA and Endeavour Energy – to design, build, and finance the project while Piambong Wind Farm is in the CWO REZ, it plans to connect to the existing network.

A Community and Employment Benefit Program is in place for the CWO REZ over the next 30 years.

An Ambitious Target for reducing renewable emissions

What are the benefits of Renewable Energy Zones?

The Renewable Energy Zones are expected to deliver multiple benefits for NSW, including:

Excellent Wind Resource

Vestas has identified the Piambong area for its strong wind resource. We are using a range of innovative instrumentation and data analysis techniques to model the wind characteristics at site.
