Megavar

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.

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 certification and electrical contractors licences in every Australian state.

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 every Australian state, and our ISO 9001, ISO 14001 and ISO 45001 certification means our quality and safety systems are independently verified. With offices in Hobart, Launceston, Adelaide, Newcastle and Gladstone, Megavar provides genuine national coverage with the responsiveness of a local team.
