This week in New South Wales, a new clean-energy landmark took shape. The Maryvale Solar & Energy Storage Project officially broke ground in the Central-West Orana Renewable Energy Zone. The hybrid facility will integrate a 243 MWp DC-coupled solar farm with a 172 MW/409 MWh battery energy storage system. It ranks among Australia’s largest sites using DC-coupled technologies to optimise output and storage management.
A Secure Future Backed by Government
Importantly, the project secured a Long-Term Energy Service Agreement under NSW’s Electricity Infrastructure Roadmap. This agreement offers a price floor that underpins financing and reduces risk. The site sits in a state-designated Renewable Energy Zone known for abundant sunshine and strong energy infrastructure support.
Smarter Renewable Energy That Works on Demand
The hybrid’s DC-coupled design lets solar energy charge the battery directly, reducing energy loss. It enables scheduled clean power delivery when the grid needs it. Once operational, the facility will deliver up to 172 MW of dispatchable electricity. That is enough to power roughly 82,000 homes and to avoid about 615,000 tonnes of CO₂ annually. The project will also boost the local economy by creating up to 360 jobs during peak construction.
What Makes This Project Unique
The official groundbreaking occurred on 14 August 2025, marking a new milestone for regional clean energy. Gentari appointed PCL Constructions‘ Solar Division as the EPC contractor. Trina Solar will supply PV modules. Contemporary Amperex Technology Australia (CATL) will deliver the battery system. AEMO Services granted the LTESA, offering financial certainty. The facility will use lithium-iron-phosphate batteries with around 2.4 hours of storage on a 360-hectare site. Commercial operation is targeted for early 2027. It now marks Gentari’s growing Australian portfolio, adding to a total of 814 MW of solar and hybrid projects under development or operation.
