Spanning across approximately 187 hectares of land, the Benger Solar Farm will be located approximately 15 km south of Harvey and 20 km north-east of the Bunbury township in Western Australia.

With a proposed capacity of approximately 100 megawatts, the project is expected to generate enough clean energy to supply around 35,000 homes. This will assist Australia in minimising carbon emissions by approximately 210,000 tonnes per year.

The project is currently under development and we are expecting to commence construction in 2020 with full operation in 2022.

The Benger Solar Farm will comprise of solar PV panels that are similar to those found on ordinary residential homes. These panels will be fastened to single-axis tracking structures that slowly rotate from east to west, tracking the sun’s movement across the sky. The tracking system increases the panels’ exposure to the sun and maximises their power output.

The electricity produced by the solar PV arrays is converted from Direct Current (DC) to Alternating Current (AC) by electronic power inverters. Next, it goes through transformers where the voltage is stepped up successively to the required level for grid connection. From there, the power flows into the grid, where it is distributed through the Wholesale Electricity Market (WEM) for the South West Interconnected System of Western Australia (SWIS). The SWIS incorporates over 7,800 km of transmission lines, making it the largest interconnected power system in Western Australia.

Our Approach

Benger Solar Farm is expected to bring empowerment and economic growth to the local community. Our continual open dialogue with local residents, community groups, the Council and relevant authorities ensures that all opinions and ideas are considered in the process. We appreciate the input from members of the local community and always strive to work in conjunction with them to resolve any enquiries about the project.

Furthermore, we have commissioned a range of in-depth environmental assessments and engineering studies to identify and manage any potential impacts to the environment. These include, but are not limited to:

  • Preservation of cultural and heritage sites;
  • Management of traffic conditions;
  • Protecting the local ecology (both flora and fauna) by managing environmental risks;
  • Surface water evaluations to ensure the integrity of the existing watercourse; and
  • Visual landscaping and using vegetation as natural screening from the surrounding area.
