UGL to construct Stage 3 of Western Downs batteryThe CIMIC Group’s specialist engineering and services provider, UGL, has been selected by Neoen and Tesla to construct Stage 3 of the 305MV/1220MWh Western Downs battery in Queensland.This follows UGL’s successful delivery of Stage 1 and early completion of Stage 2 (270MW / 540MWh) in November.For Stage 3, UGL will install 312 Tesla Megapack 2XL units, along with high-voltage infrastructure, control and switchroom facilities, earthworks and footings. UGL will also provide testing and commissioning support to ensure seamless integration to the grid.Together, Stage 1 and Stage 2 provide 540MW/1080MWh of storage capacity. Once Stage 3 becomes operational, the battery will offer a combined total of 845MW/2.3GWh.ACS group and HOCHTIEF chief executive and CIMIC Group executive chairman Juan Santamaria comments on the major renewable energy storage project.“Stage 3 of the Western Downs Battery will add 305MW/1220MWh of storage capacity to Queensland’s energy network, building on the success of Stages 1 and 2 delivered by UGL,” he said.“This expansion strengthens grid reliability and supports the integration of renewable generation in one of Australia’s most important energy corridors.”UGL managing director Doug Moss comments on Stage 3.“Western Downs Battery Stage 3 will be our tenth battery installation project and our seventh in partnership with Neoen and Tesla,” he said.“As a leader in constructing and commissioning renewable energy assets and connecting them to the grid, we are helping to accelerate Australia’s energy transition.”Construction on Western Downs Battery Stage 3 will commence February 2026 with completion expected in the summer of 2027/28.
