To enhance safety, traffic management, and incident response at Heysen Tunnels, Australia’s Department for Infrastructure and Transport partnered with McConnell Dowell. As part of the $350M South Eastern Freeway Upgrade—the primary connection between Adelaide and Melbourne—this project ensures continuous, sustainable operations in a challenging environment. Limited available space prevented the installation of fixed solar infrastructure or a full-scale solar array deployment. Additionally, the site required a dependable, 24/7 power source to support night operations and essential site facilities.

To address these challenges, McConnell Dowell deployed the Solarator™ Compact 40+ kW, a mobile, modular, and rapidly deployable power solution. This innovative system is expected to reduce carbon emissions by up to 282,000 pounds annually while generating significant cost savings of $95,000 per year in fuel expenses. With a payback period of just 2.5 years, the solution not only delivers financial and environmental benefits but also aligns with the company’s broader sustainability objectives.
