Stubbo Solar Farm

Project Overview

Stubbo Solar Farm is a 400 MW solar photovoltaic project with provision for a 200 MW/800 MWh battery, located near Gulgong in central-west NSW. Completed in 2025, Stubbo is among the largest solar farms built in Australia.

Delivered at a cost of about A$760 million, it became the first solar project backed by a Long-Term Energy Service Agreement (LTESA) to reach full commercial operation. Stubbo Solar can produce enough clean electricity to power ~185,000 homes.

Key Metrics

• Solar Capacity: 400 MWac (520 MWdc)
• Battery Storage: 200 MW / 800 MWh
• Investment: A$760 million
• Homes Powered: ~185,000
• Solar Panels: 930,000+

My Role

I served as Project Planning Manager during the latter stages of Stubbo Solar's delivery:

• Coordinating with EPC contractor (PCL Construction) to monitor construction progress
• Adapting the schedule in real-time to address challenges
• Aligning commissioning schedule with Transgrid's new substation and transmission tie-in
• Conducting weekly lookahead meetings to navigate supply chain pressures

Achievements

Through meticulous planning and weekly lookahead meetings, we navigated supply chain pressures (like global PV module shipping delays) without impacting the final completion date.

The success of Stubbo was a testament to proactive problem-solving. Upon project handover, Stubbo achieved all key milestones and earned recognition for its community contributions—over $85 million invested locally during construction.

Notably, Stubbo became the first large-scale solar project certified for full circularity of its PV panels, underscoring its innovative approach to sustainability.
