- Integration with the wind farm to create a comprehensive hybrid power solution
The solar installation has been designed to complement the wind farm's generation profile, providing power during daylight hours when mining operations are typically at their peak, while the wind turbines can continue generating electricity during night hours when available.
Construction Progress and Timeline
The solar component is advancing in parallel with the wind farm installation:
- Over 50% of panel frames installed by mid-2025
- Systematic approach implemented to minimize environmental disruption
- Integration planning with existing power infrastructure well underway
- Construction and commissioning on track for completion in 2026
Project managers have implemented careful environmental management practices during the construction phase, ensuring that the renewable energy project maintains minimal impact on the surrounding ecosystem even during its development.
