The first large-scale battery in the South-East Queensland load centre recently commenced commercial operations, providing a boost to the reliability and capability of the power grid.
CS Energy’s Greenbank Battery has been regularly charging and discharging to support market requirements since beginning commercial operations last month. It is the company’s second grid-scale battery and follows the commissioning of its Chinchilla Battery in 2024.

The 200MW/400MWh Greenbank Battery features 108 Tesla Megapack 2XL units and has the capacity to power 66,000 homes for two hours in the evening peak before needing to recharge.
The battery typically operates by storing surplus energy during low demand periods and then releasing it back to the grid when demand is high.
New CS Energy CEO Brian Gillespie said, “CS Energy worked with Tesla, Consolidated Power Projects, and Powerlink Queensland to deliver the Greenbank Battery.
“The battery has gone through a rigorous testing and commissioning process, which was similar to the approach used for the Chinchilla Battery.
“CS Energy also undertook a detailed operational readiness program, which included employee training, critical risk assessments, and safety and design reviews.
“Thank you to local residents who attended community updates held by our team during the construction phase. I would like to reaffirm our commitment to being a good neighbour now that we are in the operations phase.”
To support this phase and the ongoing operation of the battery, two experienced operator maintainers have commenced in permanent roles onsite, supported by asset and operations engineers, Tesla, and the Chinchilla Battery operations team.

The Greenbank Battery is located next to Powerlink Queensland’s Greenbank Substation, which supplies electricity to South East Queensland.
Site works for the Greenbank Battery began in late 2023 and the project had a peak construction workforce of 60 people.
