This report analyses the costs of building a grid-scale battery in Australia (the NEM and WEM). How much does it really cost to build a utility-scale battery energy storage system (BESS) in Australia? A newly released analysis from the Western Australian Economic Regulation Authority (ERA) sheds light on this question, offering a detailed cost benchmark for a 200 MW / 800 MWh standalone. For example, the Electric Mine Consortium: 2020 to 2024 report found that electric mines can operate at costs between 56% and 88% lower than their diesel-powered counterparts. For somewhere like Australia, with ambitious emissions reduction targets of net-zero scope 1 and 2 emissions by 2050. This includes innovative new technologies, such as advanced inverters and large scale battery energy storage systems, which are enabling the transition to a cleaner energy future. These systems are usually behind-the-meter and serve small factories, workshops, commercial buildings, office towers, and shopping. Need help finding the right suppliers? Try XPRT Sourcing. Higher capacity = higher upfront cost but better long-term ROI. Battery Chemistry: Lithium-ion dominates with.

Renewable energy generation also depends heavily on the location of the mine, with certain areas better suited for wind or solar power generation. Regardless, all mines will need large-scale energy storage solutions to ensure reliability, further adding to the cost and complexity of renewable power integration.
Are mining companies balancing the need for a reliable power supply?
At the same time, mining companies are balancing the need for a reliable and stable power supply to maintain productivity and reduce downtime. In the interview below, Juergen Zimmermann, Head of Business Development and Technology at Hitachi Energy, outlines some of the key challenges and opportunities facing the mining industry.
Why is capital expenditure important when building a battery energy storage system?
This has led to multiple gigawatts of grid-scale battery energy storage systems in various stages of development in Australia. Each of them requires significant investment, with millions of dollars at stake and years-long development timelines. As a result, capital expenditure, or capex, is an important consideration when building a battery.
Solar and wind energy in combination with BESS are clear pathways for the energy transition in mining, while meeting energy production needs for long-term growth. The right integration of these different components is key to success. What lessons have been learned from operational storage projects for mines?
