Hanwha Energy Australia has achieved a major milestone for its greenfield Battery Energy Storage System (BESS) located in Tangkam, Queensland, with grid connection approval from Powerlink Queensland now enabling the project to advance toward construction and integration with Queensland’s transmission network.
Located approximately 150km west of Brisbane, the 100MW/200MWh (2-hour) BESS will connect to the grid via an existing Powerlink substation and integrate seamlessly with Queensland’s transmission network.

Once operational, the Tangkam BESS will store surplus daytime solar energy for release during evening demand peaks, providing reliable energy support for an estimated 150,000 households.
The system is engineered to provide critical grid services, including system inertia traditionally supplied by coal and gas assets, helping Queensland strengthen grid resilience and move closer to its 100% renewable energy goal.
The Tangkam BESS marks another step in Hanwha Energy Australia’s mission to deliver high-impact, future-ready energy infrastructure across the country.
“Battery energy storage systems such as the Tangkam BESS project are the way forward for delivering a cleaner, greener and more reliable energy future for Australians,” Hanwha Energy Australia general manager Alberto Costa said.

“By storing energy and making electricity available when communities need it most, this BESS will help stabilise the grid, support the growth of renewable energy, and ensure Queenslanders benefit from a more sustainable and resilient power system.
“We’re excited to be taking the lead in advancing innovative energy solutions to benefit Australian energy users now and into the future.”
