Lilyvale Battery Energy Storage System (BESS) is a proposed 440 MW / 1.76 GWh grid-forming battery project about 10km south-west of Tieri in the Central Highlands region of Queensland, or about 420km north-west of Gladstone in Central Queensland.
Lilyvale BESS will charge when demand for energy from the grid is low – typically during the day when solar generation is at its peak. The BESS can then discharge back into the grid when demand is high. The project is a strategic asset that will help reduce wholesale price volatility for Queensland energy customers, and its advanced grid forming inverter technology will improve the reliability and system strength of the regional transmission network.
Lilyvale is located on a historically-cleared cattle property within one of the state’s most established mining and industrial corridors. Its proximity to existing infrastructure and position within a developed industrial landscape makes it well suited to support the next generation of energy investments in the region.
If approved, the project will use modern, proven Lithium Iron Phosphate (LFP) battery technology. LFP batteries are a modern, proven technology with a lower fire risk, thanks to their thermally stable chemistry and resistance to overheating. This makes them a safer and more reliable choice for large-scale energy storage.
Queensland’s energy needs are evolving, and reliable, dispatchable power is required as existing generation assets approach the end of their operating lives. With the state’s coal fleet scheduled for progressive retirement by 2040, flexible storage solutions are expected to play an increasingly important role.
Australia’s energy system was originally developed around large-scale traditional generation, which is most efficient at operating continuously and has limited ability to adjust output quickly. When demand from the grid is lower than the available supply, these inflexible generators may need to maintain minimum output, which can lead to flexible generation sources like solar being curtailed. This can effect overall system efficiency and contributes to wholesale energy price volatility.
Lilyvale BESS is designed to draw energy from the grid when demand is low and dispatch it during periods of higher demand. This supports grid balance, efficiency, and system stability.
By storing energy for use when it’s most needed, the Lilyvale BESS will help smooth price variability and reduce reliance on higher-cost peaking generation, putting downward pressure on energy prices for consumers, and supporting reliable power supply for Queensland homes, businesses and industry.
We know the importance of early engagement with communities and stakeholders and are guided by industry and global standards.
