Queensland’s energy future is taking a significant step forward this month with the commencement of construction on the 400-megawatt (MW) / 1,600-megawatt-hour (MWh) Teebar Battery Energy Storage System (BESS). This substantial infrastructure project, located in the Fraser Coast region, represents one of the largest battery storage facilities currently committed for construction in Queensland, poised to bolster grid stability and accelerate the integration of renewable energy into the National Electricity Market (NEM).
Atmos Renewables, the developer behind the project, has appointed battery energy storage integrator Valo to deliver the Teebar BESS, with Enerven secured for the critical balance-of-plant works, including civil works, the 275-kilovolt (kV) substation, and transmission connection. Site mobilisation is anticipated in October 2026, with commercial operations targeted for late 2028.
Queensland is actively pursuing ambitious renewable energy targets, aiming for 70% renewables by 2032 and 80% by 2035. Large-scale battery projects like Teebar are indispensable to achieving these goals by providing essential firming capacity and grid services.
Powering Queensland’s Renewable Future
The Teebar BESS will be situated adjacent to the existing Teebar Creek Substation, approximately 60 kilometres west of Maryborough. Its 1,600 MWh capacity means it can supply 400 MW of power for four continuous hours, enabling the storage of surplus solar and wind generation for release during periods of high demand, particularly the evening peaks. This capability is crucial for managing the intermittency inherent in renewable energy sources and ensuring a reliable power supply.
Valo will deploy its GridSolve Quantum2 storage system and GEMS software, a technology suite that has secured Generator Performance Standards (GPS) approval for grid-forming operation within Australia’s NEM. This advanced capability means the Teebar battery can actively contribute to system strength and stability, mimicking the services traditionally provided by synchronous generators like coal or gas plants.
“The Teebar BESS represents another important step in supporting the country’s transition to a cleaner, more resilient energy system,” said Narayan of Atmos Renewables. “The project will support Queensland’s renewable energy system and provide long-term benefits for the local community.”
Financially, the Teebar project has achieved financial close with support from Australia’s Capacity Investment Scheme (CIS), a federal initiative designed to de-risk and accelerate investment in dispatchable clean energy infrastructure. The project is also expected to generate significant local economic activity, with estimated peak construction employment of 100 to 150 workers. Public commitments linked to the federal program indicate approximately AUD $105.4 million in Australian and New Zealand procurement before the facility reaches commercial operation.
A National Surge in Battery Deployment
The commencement of Teebar’s construction is part of a broader national acceleration in battery energy storage deployment across Australia. Just this week, the 240 MW / 960 MWh Summerfield Battery Project in South Australia also entered its commissioning phase, positioning it to become the state’s largest operational battery once fully online. In Victoria, Samsung C&T Renewable Energy Australia is seeking government approval for its proposed 200 MW / 800 MWh Darnum BESS project, with construction slated for 2027.
The Australian Energy Market Operator (AEMO) has underscored the transformative impact of these large-scale batteries. AEMO chief executive Daniel Westerman recently highlighted that grid-scale batteries set the wholesale electricity price in nearly half of all NEM trading intervals during the September quarter, a significant increase from 18% a year prior. Furthermore, these batteries tripled the energy absorbed during the day to 13 gigawatt-hours (GWh), injecting 11 GWh back into the grid during evening peaks, accounting for an average of 8% of total consumption during those crucial hours.
This rapid expansion of grid-scale storage is complemented by a burgeoning home battery market. The Clean Energy Council’s latest data for the first half of 2026 revealed 276,011 home battery installations across Australia, a 52% increase over the preceding six months. Westerman noted that homes with batteries draw 70-75% less power from the grid during peak times compared to those with solar alone, reducing the need for additional generation and lowering costs for all consumers.
For households considering energy storage, the federal Cheaper Home Batteries Program continues to offer significant upfront discounts. However, the value of this rebate is scheduled to step down again on 1 January 2027. This impending reduction underscores the financial benefits of acting sooner for those looking to invest in home battery systems. Households can explore these opportunities to secure their $3,500+ home battery rebate: federal discount reduces Jan 1, 2027 before the next scheduled change.
The Role of Batteries in a Modern Grid
The integration of both grid-scale and residential batteries is fundamentally reshaping Australia’s electricity system. Grid-scale projects like Teebar provide the backbone for a stable, renewable-dominated grid, offering essential services at a large scale. Meanwhile, home batteries empower individual households to manage their own energy consumption, reduce reliance on the grid during peak periods, and, in some cases, participate in Virtual Power Plants (VPPs) to further support grid stability. Combining these solutions is key to a robust and resilient energy future.

As Australia continues its transition, the Teebar BESS stands as a tangible example of the large-scale infrastructure investments required to support a cleaner, more reliable energy network. These developments, alongside consumer-level uptake, are critical to managing peak demand, integrating more renewables, and ultimately reducing electricity costs for all Australians.
