The first delivery for the Stanwell Battery project has arrived in Central Queensland marking a mega milestone for the project.

The first consignment of Tesla Megapack 2XL units has safely arrived at the project site 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 300 MW Battery Energy Storage System with four-hour duration.

Each lithium-ion unit weighs 38 tonnes and is 8.8 metres 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 this 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,” Ms Zahra said.

“It is just one part of the 800 MW of battery energy storage capacity we have in our pipeline.

“Capable of discharging 300 MW of energy for up to four hours (1200 MWh), our mega battery will be one of the largest in Queensland.”

The Megapacks are being installed by Yurika, a Queensland government-owned company. Several local contractors are involved, and around 80 jobs are being created during the project’s construction.

The Stanwell Battery is scheduled to suply electricity to the grid starting in May 2027.
