Queensland’s energy landscape is undergoing a significant transformation, with Genex Power announcing a major reconfiguration of the first stage of its Bulli Creek Clean Energy Park. The project, located 275 kilometres west of Brisbane in the South Burnett region, will now integrate a substantial 425 MW / 1,700 MWh Battery Energy Storage System (BESS) by 2028. This strategic shift, confirmed by Genex Power on May 14-15, 2026, signals a clear market response to the increasing demand for grid stability and reliable renewable energy supply in the state.

Initially planned as a 775 MW solar farm, the first stage of the Bulli Creek development will now feature a reduced 300 MW solar capacity, with the significant battery component taking centre stage. This move underscores the growing recognition of large-scale battery storage as critical infrastructure for Australia’s energy transition, enabling more efficient integration of intermittent renewable sources like solar.

Why the Shift to More Battery Storage Matters

The decision to pivot towards a larger battery component at Bulli Creek reflects evolving market conditions within Queensland’s National Electricity Market (NEM). Battery energy storage systems are increasingly vital for firming renewable generation, absorbing excess solar power during the day, and discharging it during evening peak demand periods. This helps to stabilise the grid and reduce reliance on traditional, often more expensive, peaking gas generators.

Queensland has already demonstrated its leadership in grid-scale battery deployment. Data from Rystad Energy revealed that in April 2026, Queensland became the first state in the NEM to discharge over 100 GWh from utility-scale BESS in a single month. This milestone highlights the critical role batteries are playing in displacing gas generation, which fell by 49% from April 2025 to April 2026, reaching its lowest monthly level in over two decades.

“We are pleased to have reached this juncture with BC1 and look forward to working with the local community and our project stakeholders as we get on with the delivery of the project, with the objective to rapidly progress all workstreams ahead of a final investment decision as early as possible in CY2028,” stated Genex chief executive Craig Francis.

Mr Francis further explained that the project review and subsequent reconfiguration were undertaken to align with these changing market conditions in Queensland and to lower the overall risk profile of the development.

Project Details and Broader Impact

The Bulli Creek Clean Energy Park is a multi-stage development, with the initial phase (BC1) now projected for commissioning in 2028. The site is strategically located, aiming to contribute to Queensland’s ambitious energy targets, which include 70% renewable energy by 2030 and net-zero emissions by 2050. The addition of a 1,700 MWh battery will provide substantial dispatchable power, helping to bridge the gap when solar generation declines and electricity demand peaks.

This kind of large-scale battery deployment is crucial for managing network stability and ensuring a reliable power supply. For households, a more stable and efficient grid can indirectly contribute to mitigating rising electricity costs by reducing the need for costly emergency generation. Understanding how grid-scale batteries help manage peak demand can also inform residential energy strategies, such as how to avoid peak demand charges and slash your time-of-use electricity bills.

The Tumuruu solar and battery project, also in Queensland’s South Burnett region, recently received federal environmental approval on May 11, 2026. This project, featuring a 400 MW solar farm and a 2,000 MWh battery, further illustrates the significant investment and progress in large-scale energy storage across the state.

As Queensland continues its transition towards a cleaner energy future, the integration of substantial battery storage capacity within major renewable energy hubs like Bulli Creek will be fundamental. These projects, alongside ongoing federal support for residential battery installations, are collectively reshaping how electricity is generated, stored, and consumed across Australia.

Future Outlook

The commissioning of the Bulli Creek BESS in 2028 will add significant flexibility and resilience to Queensland’s grid. This strategic investment in dispatchable power is expected to support further renewable energy integration, moving the state closer to its long-term emissions reduction goals while aiming to deliver a more reliable and cost-effective energy supply for consumers and businesses alike.
