Gentari breaks ground on Maryvale solar-plus-storage project in regional NSW

• Gentari has begun building the 243-MWp Maryvale solar farm with a 172-MW/409-MWh LFP battery in NSW under the state’s Roadmap, targeting commercial operations in Q2 2027.

Gentari Sdn Bhd, the clean-energy arm of Malaysia’s Petronas, has started construction of the Maryvale Solar and Energy Storage project in New South Wales, advancing one of the state-backed developments selected under the Electricity Infrastructure Roadmap. The company said the groundbreaking adds to its Australian portfolio, which now totals 814 MW of solar and solar-hybrid capacity in operation and under construction.

About 37 kilometres southeast of Dubbo, Maryvale pairs a 243-MWp photovoltaic plant with a 172-MW/409-MWh lithium-iron-phosphate (LFP) battery. The storage system is designed for roughly 2.4 hours of dispatchable output—enough to shift daytime solar into the evening peak and help firm the grid as coal units retire. The site will be able to export up to 172 MW into the National Electricity Market and import as much as 91 MW to charge the battery when prices are low or renewable generation is plentiful.

Maryvale secured a Long-Term Energy Storage Agreement (LTESA) in a competitive auction run by the NSW government last summer, providing a revenue backstop that underpins investment in firming capacity. The scheme is a cornerstone of the state’s strategy to accelerate renewables, transmission and storage while maintaining reliability.

PCL Construction has been appointed as EPC contractor. Trina Solar will supply the PV technology, while Contemporary Amperex Technology Australia Pty Ltd will provide the battery components. Once commissioned—targeted for the second quarter of 2027—the hybrid plant is expected to generate enough electricity to meet the annual needs of about 82,000 homes.

For Gentari, Maryvale deepens a pipeline aimed at delivering utility-scale solar paired with storage to support Australia’s clean-energy transition. For NSW, it marks another milestone in bringing online firm, zero-emissions capacity that can respond quickly to market signals. With export, import and duration parameters geared to evening peaks, the project is positioned to play a balancing role as more variable renewables connect across the state.
