The Challenge

The Yandin Wind Farm, located approximately 175 kilometres north of Perth, comprises 51 x 4.2MW wind turbines and connects into Western Power’s 330kV electricity network via a new transmission line and terminal infrastructure.

The project is located in one of Western Australia’s strongest and most consistent wind regions and is expected to operate with a capacity factor of approximately 50%, generating enough renewable energy to power approximately 200,000 households annually.

To connect the wind farm into the South West Interconnected System (SWIS), new transmission and terminal infrastructure was required, while balancing environmental considerations, existing land use and programme constraints.

The transmission corridor also traversed multiple landowners, including the Iluka Mineral Sand Mine, requiring careful route planning to minimise impacts to mining operations and avoid ore bodies.

Environmental sensitivity was also a major consideration, with Black Cockatoo habitat present within the project area.

The Genus Approach

Genus was engaged to undertake the design and construction of the new 10 kilometre 330kV transmission line and terminal switchyard connecting the wind farm into Western Power’s network.

The terminal infrastructure was substantial, incorporating:

  • More than 150,000 tonnes of sand fill
  • Approximately 1,200 cubic metres of concrete

The terminal location was carefully selected to minimise environmental impacts by utilising existing cleared areas and tying into the existing 330kV Mid-West Transmission Line.

Genus also worked closely with Western Power to develop an accelerated delivery programme to meet project deadlines.

The project demonstrates Genus’ capability in delivering large-scale renewable energy connection infrastructure across Western Australia.

Delivery in action

The project included transmission line, terminal and associated infrastructure works.

The scope includes:

Design & Procurement

  • Design activities
  • Procurement
  • Approvals management

Civil & Earthworks

  • Bulk earthworks
  • Clearing activities
  • Dewatering works
  • Drainage installation
  • Topsoil stripping
  • Import and compaction of fill material up to 2.8 metres high

Construction & Infrastructure

  • Foundation installation
  • Cable trench installation
  • Earthing installation
  • Construction of control building incorporating steel frame and precast concrete tilt panels
  • Steelwork installation
  • Soak wells, septic systems and potable water tank installation
  • Mechanical and electrical systems installation
  • Security infrastructure installation
  • Boundary fencing installation

Electrical & Commissioning

  • Stringing works
  • Communications works
  • Testing and commissioning activities

Disciplines employed across the project included:

  • Design & Procurement
  • Foundation Construction
  • Steel Erection (towers, poles and gantries)
  • Tilt Panel Construction
  • Electrical Works
  • Stringing & Cut-ins
  • Commissioning & Handover
The outcome

Genus successfully completed all stages of works, with the 330kV transmission line and terminal commissioned in June 2020.

The full project scope was delivered without a major incident, reflecting the commitment and performance of the project team.

The completed infrastructure now connects the Yandin Wind Farm into Western Power’s 330kV South West Interconnected System (SWIS) network.

Careful route planning ensured minimal impact to the Iluka Mineral Sand Mine, while environmental surveys protected Black Cockatoo habitat throughout delivery.

The project now supports renewable energy generation capable of powering approximately 200,000 households across Western Australia each year.
