Greenbank Battery
Fast facts
- 200MW / 400MWh
- 108 Tesla Megapack 2XL units
- $300 million investment
- Commenced operations in June 2025
- Located on the traditional lands of the Yuggera Ugarapul peoples
Project overview
The Greenbank Battery is a large-scale battery in the Logan City Council area. The battery has a discharge capacity of 200 megawatts and can store 400 megawatt hours of energy. This means during the evening peak demand period, the battery can power 66,000 homes for up to two hours before needing to recharge.
The battery comprises 108 Tesla Megapack 2XL units. Each Megapack is made up of the battery module, paired with its own inverter and associated heat management systems and wiring. The Megapack is one of the safest battery storage products of its kind. Units undergo extensive fire testing and include integrated safety systems, and specialised monitoring software.
The Greenbank Battery is CS Energy’s second battery project. We also own the Chinchilla Battery, which commenced commercial operations in 2024.

Benefits
The Greenbank Battery will typically charge up when there is surplus energy during the day and then release energy to the grid when it is needed during high demand periods.
Batteries can also be turned on and off faster than power generators, so they are able to rapidly respond when there is a sudden gap in electricity supply, helping stabilise the grid and support system security and reliability.
Timeline
Construction commenced in late 2023 and the battery commenced commercial operations in June 2025.
Community
CS Energy has been engaging with stakeholders and will continue to keep immediate neighbours and the Greenbank community informed.
We've also established a Community Benefit Fund for the Greenbank Battery. Visit our Sponsorship section to learn more.

About the Greenbank battery
The battery will charge during the day when there is often an excess of solar and/or wind energy, and then release it during the evening peak when the sun is not shining and demand increases.
Batteries are fast and flexible – able to turn on and off in a fraction of a second. This means they are able to rapidly respond when there is a sudden gap in electricity supply, helping to stabilise the grid and support system security and reliability.
The Greenbank Battery will have a discharge capacity of 200 megawatts and store 400 megawatt hours of energy (200MW/400MWh), meaning it can power 66,000 homes for two hours before needing to recharge.
Batteries will play a critical role in the energy transformation and are an ideal partner for renewables because they can store excess energy produced during sunny or windy periods so it can be used later when it is needed the most.
The Greenbank Battery will also provide a range of system support services to Powerlink’s electricity transmission network. Because the battery will be able to ramp up and down quickly, it will be able to rapidly respond when there is a sudden gap in electricity supply in the grid, supporting system security and reliability.
The Greenbank Substation site was chosen for its strategic location on Powerlink’s transmission network. A battery at this location will allow Powerlink to increase the network capability by ensuring a reliable supply of high voltage electricity is maintained to South East Queensland, in particular the Gold Coast, Logan and south Brisbane areas.
Local community
Safety is the top priority for CS Energy.
We have partnered with Tesla for this project because they set the industry benchmark for energy storage product design and safety.
Megapack is one of the safest battery storage products of its kind. The units undergo extensive fire testing and include integrated safety systems, specialised monitoring software and 24/7 support.
In the rare event of a fire, Megapack is designed to prevent the spread to adjacent units and to minimise the environmental impact to communities.
Through a Greenbank Battery community benefit fund, CS Energy will invest $20,000 annually in local community organisations and initiatives from 2024 to 2026.
Vegetation between the battery and Pub Lane will provide screening from the road.
Cooling fans form part of each battery unit’s cooling system, which operate when charging and discharging. The fans emit a continuous noise when operating – the higher the fans run for cooling, the more noise emitted.
Noise modelling studies undertaken by specialist advisors indicated that noise emissions could be controlled by acoustic barriers. As a result, noise walls have been included in the project design to mitigate potential noise impacts to acceptable levels in accordance with relevant criteria.
