Proposed Tathra Wind Farm

Why wind, solar and battery?

Throughout the feasibility assessments, the opportunity to include wind, solar, and battery assets within the proposed development envelope was explored and identified as a highly advantageous option.

The Mid West is one of Australia’s most favourable regions for renewable energy. It offers:

• Strong, consistent wind—especially in the afternoon and evening

• Exceptional solar resources, with peak generation during the middle of the day

• Ideal conditions for battery storage, which enhances the performance and reliability of both wind and solar power.

These three technologies naturally complement each other. By co-locating wind turbines, solar panels, and a Battery Energy Storage System (BESS) on the same site, the project can:

• Reduce environmental impact and lower costs by sharing infrastructure such as substations, access roads, and grid connections.

• Balance energy output by smoothing fluctuations in generation and ensuring a more stable flow of electricity to the grid.

• Store surplus energy during periods of high generation and low demand, then release it during peak demand times—such as in the early evening when solar generation drops but electricity use remains high.

• Prevent grid overload by absorbing excess energy that might otherwise be curtailed, helping to maintain grid stability and avoid unnecessary waste.

• Support a more resilient energy system by providing fast-response backup power and helping to manage voltage and frequency on the network.

This integrated approach not only supports Western Australia’s renewable energy goals but also delivers a more flexible, efficient, and reliable electricity supply for the future.
