Our Projects
Megavar delivers high voltage testing, commissioning and maintenance projects across Australia, from 11kV distribution substations through to 275kV transmission terminals. Our portfolio spans substation commissioning, BESS integration, wind farm and solar farm connections, protection system upgrades, and planned maintenance programs for asset owners across every state.
Every project listed here was delivered by Megavar’s own engineers and technicians using our in-house test equipment fleet. These are not theoretical capabilities. They are real projects, with real outcomes, delivered for clients who trusted us to get it right.
Sectors We Serve
Megavar’s project experience covers the full spectrum of high voltage infrastructure across Australia:
- Transmission and Distribution Substations – New build, augmentation and replacement projects for network operators including ElectraNet, TasNetworks, Evo Energy and Ausgrid.
- Battery Energy Storage Systems (BESS) – Commissioning of utility-scale battery storage from 10MW to 100MW+, including grid compliance testing, protection commissioning and SCADA integration.
- Wind Farms – HV substation commissioning and grid connection testing for wind energy projects across multiple states.
- Solar Farms – Substation commissioning and inverter station testing for utility-scale solar installations.
- Mining and Heavy Industry – HV maintenance, shutdown testing and substation commissioning for mining operations and industrial facilities.
- Planned Maintenance – Ongoing maintenance programs for transformer testing, protection relay maintenance, circuit breaker overhauls and earth grid testing.
Project Portfolio
With more than 20 years of hands-on experience across the Australian high voltage industry, Megavar has commissioned substations, energised renewable energy connections, and maintained critical transmission infrastructure from Tasmania to Queensland. Our multi-disciplinary team brings together commissioning engineers, protection specialists, primary testers, design engineers and project managers to deliver safe, compliant project outcomes every time.
What sets Megavar apart from other commissioning companies is the breadth of our capability. We design the protection schemes, we commission the assets, and we maintain them throughout their lifecycle. This end-to-end understanding means fewer interfaces, faster delivery, and better results for our clients.
Our project experience includes work for transmission network operators, renewable energy developers, EPC contractors, mining companies, and industrial asset owners. We hold ISO 9001, ISO 14001 and ISO 45001 accreditation and electrical contractors licences in every Australian state and territory.

Why Clients Trust Megavar With Their Projects
Megavar is not a labour hire company that places individual contractors on your site. We deliver complete project teams, managed by our own project managers and supported by our own test equipment fleet. Our commissioning engineers use Omicron, Megger, AEMC and other specialist equipment every day on live substations. When we provide commissioning services, your project benefits from this depth of daily, hands-on experience.
We hold electrical contractors licences in all Australian states and territories, and our ISO 9001, ISO 14001 and ISO 45001 accreditation means our quality and safety systems are independently verified. With offices in Hobart, Launceston, Adelaide and Newcastle, Megavar provides genuine national coverage with the responsiveness of a local team.
