About the Project

The proposed Hills of Gold Wind Farm is located about 5km south of Hanging Rock and 8km south-east of Nundle and is contained within three Local Government Areas: Tamworth Regional Council, Upper Hunter Shire Council, and Liverpool Plains Shire Council.

The Project will involve the construction, commissioning and operation of a wind farm with up to 70 wind turbine generators and associated ancillary infrastructure to support a generating capacity of up to 420 megawatts.

Once constructed, and with the backing of ENGIE’s local and global expertise in renewable energy, the Hills of Gold Wind Farm will supply up to 1,100 gigawatt hours per annum, the equivalent energy to power 185,000 average Australian homes.

Subject to project approvals the proposed wind farm could include wind turbines as well as associated infrastructure including:

Wind turbines 
Following further consultation and a greater understanding of the proposed site and surrounding areas, there has been a revision from 97 to 70 wind turbine generators (WTGs) including towers, blades, and a generator housing. The turbine towers will be supported by underground concrete foundations. The turbine may include internal transformer and protection equipment or have this equipment co-located in a small housing next to the turbine base.

Access tracks
The construction of the wind farm will require the improvement of some local public roads and bridges leading up to the project site. Each turbine will be linked to project roads using gravel tracks. Each turbine location will also include a gravel area to support the cranes used to lift the turbine components.

Electrical cables
Turbines will be linked by an underground 33kV electrical cabling and fibre optic communications cabling.

A substation will collect the internal underground 33kV cables and step up the voltage to 330kV in order to transmit power to the national electricity market. The project will assess a range of connection options to determine the most suitable route.

Meteorological monitoring masts
Multiple lattice frame masts extending to the generator height will be constructed to enable monitoring of wind speed and direction

Ancillary facilities
A maintenance and storage shed will be constructed together with a site office and car parking facilities
