Brunstock supplied the 15 MWh BESS at Monarto Energy Park and it is up and running. The set up includes 3 x 5 MWh Brunstock energy storage units or DC blocks, with charging rates of 0.5C, totalling 15 MWh.

Monarto, in South Australia’s Murraylands, is known for its wide, open landscapes and a sense of space that feels increasingly rare. Rolling mallee scrub, quiet country roads and big skies give the area a calm, unhurried character, with conservation land and rural properties shaping much of the scenery. The local community is small but deeply connected, built around long-standing farming families, volunteers and local businesses that look out for one another. It’s the kind of place where people still stop for a chat, where community events matter, and where the countryside

remains as much a part of daily life as the people who call it home.

The Brunstock Australia team, with personnel in Sydney (NSW) and Brisbane (Queensland), flew down to Monarto on several occasions to assist with the installation and commissioning of the equipment.

In addition to the 15 MWh battery energy storage system for Flow Power’s Monarto Energy Project, Brunstock’s solution included three 5 MWh battery energy storage containers (with 4.6MW inverter output) and a step-up transformer station, including our SF6-free switchgear.

This renewable energy site in South Australia contaisns a 5 MW solar farm paired with our 15 MWh BESS. Like all renewable energy sites, the battery storage component provides stability and load balancing for managing peak demand.

Supporting FCAS (frequency control ancillary services), Brunstock BESS will help make the region’s electricity grid strong and stable. South Australian businesses need more energy than ever, and this project is part of the broader solution to meet that demand with clean, reliable power.
