About OZARC

Built for the Challenges of Remote Power.

OZARC is an Australian energy infrastructure business focused on practical hybrid power solutions for remote workers’ camps and industrial operations. With a strong Northern Territory focus, our team combines industry relationships, commercial development, engineering, international supply chain expertise and local delivery capability. We are building a business around dependable power, practical technology and long-term customer relationships.

Our purpose

Making Remote Power More Practical.

Our purpose is to help remote operators access reliable electricity with greater flexibility and reduced dependence on diesel-only generation. We believe the right power solution should be shaped by the site, not by a particular piece of equipment. That means understanding customer needs first, selecting suitable technologies, validating the economics and building the capability to support systems throughout their operating life.
