Installation of Brunstock BESS at Naracoorte in South Australia, February 2026
4 March 2026
Last month our three 5 MWh BESS blocks and two step-up skid stations arrived on site in Naracoorte, South Australia. It was a stunning day and the installation all went according to plan.

Soon Kookaburra Power Technologies will be supplying a 15 MWh battery energy storage system (BESS) for Flow Power’s Naracoorte Energy Project. The system comprises three 5 MWh battery containers, each delivering 4.6MW of inverter output, along with a step-up transformer station—all manufactured by Swiss company Brunstock.
Situated in South Australia, the Naracoorte site will feature a 5 MW solar farm integrated with the BESS. This pairing enhances grid reliability and supports load balancing, particularly during peak demand periods.
The KTECK BESS will also provide FCAS, contributing to a more stable and resilient electricity grid. As energy consumption continues to rise across the state, the Naracoorte project plays a vital role in delivering clean, dependable power to local businesses and communities.
KTECK is the exclusive Australian representative Brunstock, a company committed to sustainable energy solutions. Brunstock’s battery energy storage systems are purpose-built for Australia’s harsh and remote environments. From precision welding and durable exterior finishes to a galvanised steel base, every component is designed for long-term performance.
Inside each cabinet, liquid-cooled batteries meet both IEC and Australian standards, ensuring high reliability and efficiency. Brunstock BESS supports rapid frequency modulation and network development, making it ideal for modern grid applications.
Our KTECK battery energy storage systems integrate long-life batteries, a BMS, a thermal management system (TMS), a safety management system (SMS) and an intelligent power distribution system (IPD) in a 20-foot standard container.
The Naracoorte BESS project will feature three of our 5 MWh battery containers, giving a total of 15 MWh. These are further customised to output 4.6 MW through the inverter.
We are proud to work with Flow Power on both the BESS and the required step-up transformers for the Naracoorte Solar Farm. The equipment arrived in Australia and went to the site in February 2026 and is undergoing testing and commissioning.
