Current Project Progress

The Grevillea Wind Farm project is currently in the Early Development phase. The site has been carefully selected with technical, environmental, social and commercial considerations in mind. The project is expected to progress to the Late Development phase in 2025.  

Site Identification
Prospective wind farm sites are selected based on analysis of available wind resource information, proximity to the existing high voltage electricity grid, population density in the area, existing land use, and an assessment of likely site constraints and opportunities.

Feasibility
Discussions with potential host landowners begin, along with on site wind monitoring. Grid connection enquiries are lodged with Western Power, and further desktop studies are completed to better understand the suitability of the site.

Early Development
Land agreements are secured with host landowners, and community consultation begins with neighbour properties. Wind monitoring masts are erected, and environmental surveys commence to support the approval process.

Late Development
Development and environmental approval referrals are now submitted. Community consultation and engagement activities continue, while grid connection studies are undertaken, and contracts are negotiated for a lead contractor to build the wind farm.

Financing

Contracts are negotiated for customers to purchase the electricity from the facility and, where necessary, third-party financiers are brought into the project.

Construction
Early works begin with access roads and site construction compounds. This is followed by turbine foundation excavation and construction, cable laying, substation and transmission line construction. Finally, the wind turbines are assembled and commissioned. Community engagement activities continue.

Operations
The wind farm is now in operation for the next 30 years in accordance with approval conditions. Compliance with approvals and management plans are monitored and reported throughout the wind farms life.

Decommissioning
At the end of the wind farm life, the wind farm is decommissioned and all above ground infrastructure is removed. Opportunities to repower the site with a new wind farm are explored at this stage. If no further wind farm is developed and built, the land is returned to its original use.
