CIMIC Group’s specialist end-to-end engineering and services provider UGL has supported the installation of a 270MW/540MWh battery system for Neoen, an independent renewable energy producer.
This installation, which includes associated high voltage infrastructure, comprises stage one of the Western Downs Green Power Hub, located around 250km west of Brisbane, Australia.

The hub is also seeing an expansion with UGL’s assistance in delivering stage two of the project, which was announced in August 2024.
At that time, CIMIC executive chairman Juan Santamaria said: “With greater capacity, Western Downs Battery will have an even more crucial role in Queensland’s rapidly accelerating energy transition, as the state strives to reach 80% renewable energy by 2035.”
This stage two project entails constructing an additional 270MW/540MWh battery and the necessary high-voltage infrastructure to integrate it into the grid.
The new battery will comprise 140 Tesla Megapack 2XL units and is slated to commence operations in 2026.

This integration will enable stored energy to be efficiently transmitted into the electricity network, enhancing the overall reliability and sustainability of the power supply.
In a separate development, CIMIC subsidiary Leighton Asia recently secured a contract for the construction of Elan The Emperor, a luxury residential project in Gurugram, India.
Construction work is scheduled to start in September 2025 and be completed by 2030.
