Spain-based Ingeteam will provide power conversion systems and control technology for a new hybrid solar and battery energy storage project in eastern Australia, the company said on Monday.
The Maryvale solar and storage facility, located in New South Wales, will combine 243 megawatts-peak (MWp) of photovoltaic (PV) capacity with a 172MW battery energy storage system (BESS), capable of operating for 2.4 hours. The project is owned by clean energy firm Gentari and marks the first DC-coupled solar-plus-storage plant to be developed in the region, according to Ingeteam.
Under a newly signed agreement, Ingeteam will supply 32 power stations comprising 61 central PV inverters and 488 units of 430kW DC-DC storage converters. The company will also install a hybrid plant controller to coordinate operations across nearly 400,000 solar panels and 122 battery containers.
“We are delighted to continue contributing our technology to decarbonising the energy mix of the Australian National Electricity Market,” said Ana Goyén, director of solar PV and BESS at Ingeteam.
Construction of the project will be led by PCL Solar, following Gentari’s notice to proceed on engineering, procurement, and construction (EPC) works.
The hybrid system will operate in DC coupling mode, allowing batteries to be charged directly from solar power without intermediate conversion losses. Ingeteam said this approach improves efficiency by enabling energy to be stored when prices are low and discharged during high-demand periods, such as evening peaks.
“Projects integrating solar and storage technology aim to balance sustainability and energy security, while offering greater potential for managing the solar resource and generating energy much more efficiently,” Goyén added.
Once operational, the plant will have a maximum export capacity of 172MW and an import capacity of 91MW to the Australian National Electricity Market. It is expected to generate over 520 gigawatt-hours (GWh) of clean electricity annually, enough to supply around 82,000 households and avoid approximately 412,000 tonnes of CO₂ emissions each year.
Commissioning is scheduled for the second quarter of 2027.
