• The Crisafulli Government is delivering more affordable, reliable and sustainable power, with four big battery projects in three months to help drive downward pressure on power prices.
• Another 940 MW of storage to power up nearly 1 million homes at peak demand. 
• The Crisafulli Government’s Energy Roadmap is delivering affordable, reliable and sustainable energy for Queensland, with a 10 per cent drop in power prices expected next financial year, under the Default Market Offer.
• The Crisafulli Government is delivering a plan for Queensland’s future and a better lifestyle through a stronger economy.  

The Crisafulli Government is delivering more affordable, reliable and sustainable power with four big battery projects reaching key connection and market milestones across the State. 

In the past three months, Powerlink has energised the second stage of Quinbrook’s Supernode battery at Brendale, while Iberdrola Australia’s Broadsound battery is also undergoing testing and commissioning. Big batteries at Stanwell and Woolooga are now energised into the grid.  

Once fully operational, the four batteries will provide a combined 940 megawatts (MW) of storage – enough to power up to 940,000 homes at peak demand. 

It’s just one of the ways the Crisafulli Government is delivering a plan for Queensland’s future and a better lifestyle through a stronger economy, after a decade of decline under Labor.  

Treasurer and Minister for Energy David Janetzki said with the addition of large-scale storage, the Crisafulli Government was putting downward pressure on energy prices.  

“Big batteries play an important role in capturing excess energy throughout the day and discharging it during the evening peak when demand and prices are highest,” Treasurer Janetzki said.  

“The private sector has realised the opportunity to build big batteries in Queensland, and we are leading the national market. 

“This is our Energy Roadmap in action. More storage on the grid means more supply when Queenslanders need it most and more downward pressure on prices. 

“Once these projects are operational, more than two gigawatts of large-scale battery storage will have come online since mid-2025, providing essential firming capacity to support new energy generation.” 

Treasurer Janetzki said the Crisafulli Government was continuing to invest in the infrastructure that will put downward pressure on wholesale prices. 

“After a decade of decline under Labor in which power prices rose by nearly 20 per cent in a single year, our Energy Roadmap and investment in generation, firming and storage is flowing through to prices with household energy bills to fall about 10 per cent next financial year.”  

Minister for Finance, Trade, Employment and Training Ros Bates said the milestones highlighted the Crisafulli Government’s commitment to delivering investment certainty and stability, including for Queensland’s global partners. 

“This is another demonstration of how Queensland is open for business, with the Crisafulli Government rebuilding and resetting our investment relationships after a decade of decline under Labor,” Minister Bates said.  

“By securing these investments from Quinbrook and Iberdrola, we are strengthening Queensland’s energy future and supporting long‑term affordability for households and businesses across the State.” 

Powerlink’s interim chief executive Darryl Rowell said Powerlink had connected nine big battery projects in the past year, totalling more than 2GW of storage. 

“The pipeline for BESS connections remains strong with a connection agreement with Quinbrook for the third stage of their Supernode BESS at Brendale being executed right now,” Mr Rowell said.  

“We are seeing the value in batteries in giving us flexibility in operating and adding strength to the state’s power system.”
