The first consignment of Tesla Megapack 2XL units for the Stanwell Battery project has arrived in Central Queensland, marking a major milestone for the construction team.
The Stanwell Battery is being constructed adjacent to Stanwell Power Station near Rockhampton. In total, 324 Megapack units will arrive on site over the next few months and together will make up Stanwell’s 300MW Battery Energy Storage System with 4-hour duration.

Each lithium-ion unit weighs 38 tonnes and is 8.8m long—the length of a city bus. They are being transported daily on drop-deck semi-trailers from Brisbane to Stanwell via the Bruce Highway, Capricorn Highway and Power Station Road.
By September, all Megapacks will be sitting in place, stored in a safe “shipping mode” until commissioning commences in November 2025.
Stanwell central generation general manager Angie Zahra said the delivery was a significant milestone for Stanwell’s portfolio diversification efforts.
“The Stanwell Battery is part of the diversification of our portfolio, to include cleaner and more flexible energy solutions,” she said.
“It is just one part of the 800MW of battery energy storage capacity we have in our pipeline.

“Capable of discharging 300MW of energy for up to four hours (1200MWh), our mega battery will be one of the largest in Queensland.”
The Megapacks are being installed by Yurika, a Queensland government-owned company.
The Stanwell Battery is scheduled to supply electricity to the grid starting in May 2027.
