Power the future of switched on infrastructure
Australian engineers design, integrate and commission your microgrid and power conversion solution, with the same local team here to service and maintain your system throughout its life.
From feasibility to commissioning and long-term service, our engineers stay across every layer of the system.
We design, integrate, commission and maintain the power systems that let mining, remote communities, industry and defence run on their own terms. Our capabilities across grid-forming microgrids, battery energy storage, power quality solutions, spinning reserve, STATCOMs and charging are delivered as one connected system rather than a pallet of parts. From feasibility and energy modelling through to grid connection, commissioning and long-term service, our engineers stay across every layer, so the system that goes live is the one that was actually designed.
That matters because power infrastructure is only as good as the thinking that holds it together. We provide a clear path to lower running costs and reduced emissions. Sites navigating AEMO and NER requirements get engineers who’ve done it before, not a first attempt. Asset owners get equipment chosen for their site’s conditions, not based on the vendor OEM relationship. The result is a power system built around the customer’s operation.
Switching on Australia’s hardest working power applications
From grid-forming inverters to switchboards, we take ownership of the full project and electrical balance of plant.
We deliver integrated battery energy storage systems for energy shifting, peak shaving and grid services, engineered as a complete power conversion and storage package. Our team manages the full deployment, from sizing and integration through to long-term performance monitoring, so stored energy is there exactly when the site needs it.
We develop hardware-benchmarked power system models using PSSE, PSCAD and PowerFactory, giving every project a validated technical foundation before it goes to site. This modelling underpins grid connection approvals, GPS conformance and performance capabilities to prove designs before deploying in the field.
Our microgrid controllers are built in-house on Colterlec’s proprietary technology, giving us full control over the layer that ties generation, storage and load together. Rather than relying on third-party control platforms, we design and tune this technology to each site’s specific conditions, and deliver systems that perform.
We deliver fast-response spinning reserve solutions using grid-forming, inverter-based resources — replacing the role traditionally played by thermal generation to keep weak or islanded networks stable during load changes and disturbances. Our team designs and tunes these systems against real site conditions, supported by dynamic modelling, so reserve capacity responds the moment it’s needed.
We deliver dynamic power quality solutions that stabilise voltage, dampen oscillations and support weak grid connections. From sizing through to commissioning, our engineers manage the full STATCOM deployment and provide ongoing performance support, helping networks and industrial sites maintain reliable power quality as more variable renewable generation comes online.
How we work
Our full lifecycle delivery model translates to fewer handoffs, faster answers and a power system that keeps performing long after it’s switched on.
Develop & Design
We start with feasibility studies, energy modelling and system architecture - matching the technology to your site's actual conditions.
Bid & Contract
Clear technical and commercial proposals so everyone knows what's being delivered and how, before work begins.
Delivery
Engineering, procurement and supply chain management handled end-to-end by our team, keeping the project moving.
Commission & Handover
Full system testing, performance validation and operator training so the system that goes live is proven to perform, and your team knows how to run it from day one
Service & Maintain
Long-term maintenance, condition monitoring and remote support from the same team that built the system, keeping it performing long after handover.
Local engineering to navigate compliance complexity
Proprietary controller technology at the core of every project
Our microgrid controllers are developed in-house on Colterlec’s proprietary technology — giving us full control over the control layer that ties generation, storage and load together. Rather than relying on third-party control platforms, we design and tune this technology to each site’s specific conditions, so your solution performs the way it was engineered to.
Industries

Secure, resilient power systems built to the highest standards of compliance and independence, supporting energy sovereignty for defence bases and government facilities.
Frequently Asked Questions
What is a grid-forming inverter, and why does it matter?
Grid-forming, inverter-based resources (IBR) allow a power system to set voltage and frequency independently — replacing the role traditionally played by spinning thermal generators. This is the core technology enabling renewables-led microgrids and grid stability as coal retires.
How much does a mining microgrid cost?
Mining microgrid and hybrid power projects in Australia typically range from $10M to $100M+, depending on scale, renewable penetration and site complexity. Remote community and industrial systems are generally smaller, from $2M–$50M.
What's the difference between a BESS and a microgrid?
A Battery Energy Storage System (BESS) is one component — storing and dispatching energy. A microgrid is the complete system: generation (solar, wind, diesel/gas), storage, and the control layer that lets it operate independently of, or alongside, the main grid.
Do you provide grid connection and AEMO compliance support?
Yes. We manage NER and AEMO grid-connection navigation, including GPS conformance, R0/R1/R2 stages, and dynamic modelling (PSSE, PSCAD, PowerFactory) for hardware-benchmarked, compliant designs.
Can existing diesel power stations be converted to hybrid renewable systems?
Yes — hybrid retrofits combining existing diesel/gas generation with new solar and BESS are one of the fastest, lowest-risk paths to diesel displacement for remote sites already running thermal generation.
