Ingeteam to Power Gentari’s Pioneering NSW Solar-Storage Hybrid by 2027

• Ingeteam will equip Gentari’s 243-MWp Maryvale solar-plus-storage project in New South Wales, using DC coupling to maximise output before its 2027 debut.

Spanish power-conversion expert Ingeteam has won the technology package for Maryvale, eastern Australia’s first DC-coupled solar-plus-storage project, marking a breakthrough in the way large-scale renewables and batteries will interact on the National Electricity Market.

Backed by Malaysia’s Gentari, a clean-energy subsidiary of Petronas, the plant will pair 243 MWp of photovoltaic arrays with a 172-MW/2.4-hour battery energy-storage system near Wellington in central New South Wales. Once fully commissioned in the second quarter of 2027, the hybrid installation is expected to pump more than 520 GWh of green electricity into the grid each year—enough to power roughly 100,000 Australian homes and shave peak-hour demand on the state’s coal-heavy system.

The contract calls for Ingeteam to deliver 32 prefabricated power stations housing 61 central PV inverters as well as 488 430-kW DC-DC converters that channel surplus solar output directly into the battery racks without the efficiency losses inherent in AC conversion. The company will also deploy its hybrid power-plant controller, orchestrating nearly 400,000 bifacial modules supplied by Trina Solar and 122 battery containers sourced from CATL. The DC architecture will let the site charge batteries at full tilt during midday oversupply and discharge clean energy in the early evening when wholesale prices spike.

Civil and electrical works are being steered by PCL Construction’s solar unit, which must integrate the project’s 172-MW export and 91-MW import limits into a new substation and transmission link. Maryvale secured a 20-year Long-Term Energy Service Agreement (LTESA) in last year’s tender run by AEMO Services, guaranteeing a minimum revenue floor and accelerating Gentari’s final investment decision. A notice to proceed went out in early March, setting in motion a three-year build programme that includes grid-connection studies, flood-plain mitigation and biodiversity offsets.

Gentari views Maryvale as a template for its broader Australian ambitions, which span green-hydrogen production and additional solar-storage hubs in Queensland and Victoria. For Ingeteam, the project extends a decade-long presence in Australia and reinforces the company’s status as a go-to supplier for hybrid plants that must juggle intermittency, storage and ever-tougher grid-code requirements.
