For UGL’s new energy team, sustainability isn’t just a goal — it’s how we deliver.
As part of our commitment to smarter, greener solutions, we deployed a 44kW mobile solar plant with 100kWh of battery storage at Neoen Australia’s Collie Battery site in Western Australia. This renewable system is supporting the energy needs of our construction offices — reducing diesel reliance, lowering emissions, and cutting operational costs, all while delivering reliable, efficient power during early construction.
Rethinking construction power
Reliable power is essential, especially in the early phases of major infrastructure builds. Traditionally, sites have relied on diesel generators — but with environmental impacts and rising fuel costs, this approach is no longer sustainable. Our hybrid solar-battery setup presents a cleaner, smarter solution, combining renewable energy with built-in storage for resilient power, day or night.
Where to next?
Building on the success at Collie, UGL's Muchea Battery project in Western Australia and the Western Downs Battery project in Queensland also incorporated mobile solar plants. UGL plans to continue expanding the rollout of these mobile solar plants on future projects where space allows. This approach supports our broader goal of scaling up renewable energy use.
This initiative is one of many that demonstrates UGL’s broader vision: delivering practical, scalable sustainability solutions that don’t just tick boxes — but truly change how we build the future of energy.
About Collie Battery
UGL was first appointed by Neoen to construct their 219 MW / 877 MWh Stage 1 of Collie Battery and associated energy infrastructure in Western Australia. We were responsible for the design, construction, testing and commissioning of the 33/330kV substation on site, the installation of Tesla 2XL Megapacks and associated balance of plant infrastructure. UGL’s scope also included the replacement of an existing bridge and construction of an access track to the site.
UGL was selected to continue supporting Neoen with the construction and now completed Stage 2 of Collie Battery sized at 341 MW / 1363 MWh. Our scope of work covered preparing the site for the installation and connection of 348 Tesla Megapack 2 XL units, installation of high voltage infrastructure, control and switchroom facilities, delivering safety protection measures, and undertaking earthworks and footings. UGL also installed the Tesla Megapack 2 XL units and providing testing and commissioning support.
Neoen’s Collie Battery connects into Western Power’s substation, to easily charge and discharge energy from Western Australia’s South-West Interconnected System (SWIS).
