Sungrow joins ENGIE and Elecnor for Australian battery project

Sungrow will supply battery technology for the 150MW Hazelwood storage facility in Victoria, Australia.

Key points

  • Sungrow partners with ENGIE and Elecnor for Hazelwood BESS.
  • Project features 150MW/300MWh capacity using PowerTitan 2.0 technology.
  • Grid-forming capabilities aimed at supporting renewable integration.

Power Technology reported that technology provider Sungrow has entered into a collaboration with ENGIE and Elecnor to develop the Hazelwood battery energy storage system in Victoria, Australia. The installation features a capacity of 150MW and 300MWh, marking another step forward for large-scale energy storage infrastructure in the country.

Under the arrangement, Sungrow's local subsidiary is tasked with supplying the core equipment. The site will deploy 66 units from the manufacturer's PowerTitan 2.0 product line, specifically utilizing the ST5015-UX battery energy storage system. Furthermore, the design incorporates 33 SC6900UD-MV power conversion system inverters alongside the proprietary EMS3000 smart controller. Meanwhile, Elecnor has been designated as the balance-of-plant contractor for the construction phase.

The engineering configuration focuses on utility-scale deployment, offering liquid-cooled thermal management, advanced monitoring tools, and robust power conversion mechanisms designed to ensure long-term operational safety. The facility will also integrate grid-forming capabilities to assist in maintaining network frequency and voltage stability, allowing the system to react swiftly to fluctuations in electrical conditions.

According to project stakeholders, these advanced technical attributes will facilitate the incorporation of variable renewable generation as its proportion of the total electricity supply continues to expand. The installation is intended to act as a flexible resource for the state of Victoria and the broader National Electricity Market by capturing surplus power during periods of low consumption and discharging it during peak demand intervals. Thomas Hou, the managing director of Sungrow Australia, stated that the initiative marks an important milestone for grid-forming energy storage and network resilience.

This development builds upon Sungrow's growing portfolio of international projects. In August 2026, the company secured a contract with Verano Energy to supply a 152MW/606MWh battery storage installation for the Observatorio initiative in Chile, illustrating the expanding global footprint of major renewable supply chain vendors.

Why it matters

As power grids worldwide incorporate higher shares of variable renewable generation, managing frequency and voltage stability becomes a critical engineering priority. Australia presents an interesting benchmark, with World Bank figures indicating electricity use per person reached 9,794.7 kWh in 2025, while the renewable share of electricity output stood at 26.7 percent in 2021. Large-scale battery storage facilities such as the Hazelwood installation demonstrate how utilities and developers are utilizing advanced grid-forming inverters to bridge supply and demand gaps. For emerging economies in Africa, including Nigeria, observing these international advancements provides valuable technical insights into how utility-scale storage can eventually support grid reliability as decentralized and renewable power sources scale up.
