Powerlink plays a key role in influencing the energy system of the future, one that balances customer needs, while moving to a lower carbon future that includes battery and storage solutions, grid and generation technologies, and demand management. 

Large-scale battery energy storage systems (BESS) involves a large number of battery modules being installed together. This approach can deliver numerous advantages to make the energy network more secure and stable, support the shift to renewables and contribute to reducing electricity costs to customers. 

Powerlink has investigated the potential for batteries to be cost-effectively installed and connected to the transmission network at various locations in Queensland. By connecting to the transmission network in a coordinated way, the battery connection will deliver scale-efficiencies and operational cost-effectiveness.

We ran an Expression of Interest (EOI) to engage with external developers, investors and stakeholders in examining potential BESS opportunities to generate innovative commercial and technical models that are mutually beneficial.  

The process was innovative and highly competitive, aimed at ensuring optimal outcomes for Powerlink, and ultimately Queensland consumers.  We have worked with large-scale battery developers to identify the optimal battery solutions to be located at established substation sites in Queensland. 


Powerlink has signed an agreement with CS Energy to install a grid-scale battery at Powerlink's Greenbank Substation. As part of this work, we will be connecting a new 200MW battery (with 400MWh storage) into the Greenbank Substation, which supplies electricity to South East Queensland, in particular the Gold Coast, Logan and South Brisbane areas.

This is Australia’s first truly cooperative BESS utilisation and optimisation scheme, partnering a transmission network provider with a generation and retail business.

Construction will begin in 2023 and will continue for a period of 18 months, subject to good weather and site conditions.
