Energy solutions provider Gentari has commenced work on the Maryvale Solar & Energy Storage project, a hybrid facility combining a 243 MWp solar power plant with a 172 MW/409 MWh Battery Energy Storage System (BESS). Located in the Central-West Orana region of New South Wales, the project ranks among the largest in Australia to use DC-coupled technologies, optimising production and storage management.
A contract secured under New South Wales’ Infrastructure Roadmap
The Maryvale project was awarded a Long-Term Energy Service Agreement (LTESA) under the New South Wales Electricity Infrastructure Roadmap. This mechanism, administered by AEMO Services Limited (ASL) as the Consumer Trustee, guarantees an energy price floor, thereby supporting the bankability and financing of the project.
The site is strategically located in the Central-West Orana Renewable Energy Zone (REZ), one of the priority development areas designated by the regional government for large-scale energy projects. The location was selected for its high solar irradiance and capacity to host grid and transmission infrastructure.
Storage and dispatchable energy production
The system’s DC-coupled design allows direct management of excess solar generation into the batteries, with scheduled dispatch according to grid demand. This configuration increases the site’s flexibility, enabling it to provide dispatchable renewable energy while delivering essential ancillary services for grid stability.
According to Gentari, the installation will be capable of delivering up to 172 MW of dispatchable electricity, equivalent to the annual consumption of around 82,000 households. At peak construction, the site could employ up to 360 workers.
A project delivered by established industrial players
Project execution has been entrusted to the solar division of PCL Construction, acting as EPC contractor. Key components were sourced through direct procurement from Tier 1 suppliers: Trinasolar for the photovoltaic modules and Contemporary Amperex Technology Australia Pty Ltd for the BESS system. The Notice to Proceed was issued in January 2025.
With this development, Gentari brings its total installed and under-construction solar and hybrid capacity in Australia to 814 MW.
