In Australia Brunstock is helping developers and asset owners deploy battery energy storage systems with more flexibility and less risk. Energy storage isn’t just about batteries—it’s about integration that works.
Across the BESS projects we’ve been involved with, one thing keeps surfacing in project discussions: most delays and risks don’t come from the batteries—they come from what connects them. At Brunstock, we’ve developed a set of optioned containerised BESS models to give project teams the clarity and flexibility they need, without compromising on safety or standards.
🟧 Semi-integrated configurations provide a compliant foundation with battery racks, cooling, fire suppression, and earthing—perfect for teams who want control over PCS, EMS, or site-level integration.
🟩 Fully integrated systems come pre-assembled with batteries, BMS, HVAC, fire protection, with PCS, EMS—ready to drop in, connect and commission with minimal on-site work.
What ties them together is our commitment to:
✔ Matching AS/NZS requirements (as well as the local standards required in other relevant countries)
✔ Prioritising operator safety
✔ Reducing project risk through clearer integration and documentation
Speed matters in energy storage, but durability and compliance can’t be compromised. At Brunstock, we focus on delivering practical, safe and integration-ready BESS systems, where success comes from getting the details right early, with clear documentation, defined interfaces, and shared accountability.
Many manufacturers only offer bundled systems—with the battery, controls and design locked into one package. That’s often too rigid for IPPs, VPPs or developers with preferred equipment, contractors or existing network requirements.
Brunstock takes a different approach. As a subsidiary of Brunstock AG, we offer a state-of-the-art BESS that integrates seamlessly with your preferred PCS, EMS and delivery partners, giving you full control over the rest of your project.
We also bring strong local capability. While our lithium-iron batteries are produced by a Tier 1 global provider, we maintain full QA oversight from factory to site. Our Australian-based engineering team supports integration, commissioning and ongoing support, reducing risk and keeping projects on track.
Recent and ongoing projects include:
- 60+ MWh of BESS delivered nationally, supporting renewable integration
- Multiple MWh systems planned, with continued rollout planned into 2026
- Backed by a proven Tier 1 supply partner, with over 12 GWh of battery cells produced annually
Our systems are designed to:
- Unlock revenue through arbitrage, FCAS, and peak demand management
- Reduce BESS capex through flexible system architecture and vendor choice
- Integrate seamlessly with your preferred PCS, EMS, and contractors—no lock-in model
- Meet Australian standards, with QA from factory to site
- Reduce delivery risk through local engineering and responsive support
The Brunstock point of difference
What sets Brunstock apart from competitors in Africa, Australia and Europe is the flexibility we offer. In the battery energy storage market, many companies only sell bundled systems; you’re expected to take their battery, controls and design as a single package. That’s often too rigid for developers who may have preferred equipment, contractors or existing network controls in place.
We take a different approach. Our high-quality battery energy storage solutions are products that integrate easily with a variety of systems. This gives customers or end users the freedom to tailor the rest of their project as they see fit, without being tied to one vendor’s model. We offer flexibility on integration. We have an open ecosystem, which means we can use a customer’s EMS or invertor rather than supplying our own, if they prefer.
We also bring strong local support. While our lithium batteries are manufactured overseas, we personally oversee quality control and testing before shipping. Once in the local region, we provide hands-on support during installation and commissioning to keep projects moving smoothly. This reduces delays and gives our customers confidence from start to finish.
Our team has deep experience in energy, infrastructure and construction. We understand budget pressure, tight timelines and compliance challenges, not to mention the importance of aligning to Australian Standards, SANS and EN. We don’t push a one-size-fits-all solution; we focus on getting the right outcome for each project.
With all this flexibility, you might think the costs would go up, but we are keeping our business agile and nimble. This lets us tender, design, manufacture and deliver energy storage systems at speed with attractive prices.
