Replacing traditional diesel in a major tunnel upgrade project with Solarator Compact 50+ kVa

Case Studies

Overview:

Australia’s Department for Infrastructure and Transport appointed McConnell Dowell to manage the safety, traffic management, and incident response capabilities of Heysen Tunnels. This project was part of the $350M South Eastern Freeway Upgrade providing the most direct connection between Adelaide and Melbourne.

Key challenge:

The site does not have enough real estate for a fixed solar infrastructure or full roll-out of solar arrays. It also requires continuous, reliable energy for night operations and site hut power.

Solarator® solution:

With our mobile, modular, and rapidly deployable Solarator® Compact 50+ kVa, McConnell Dowell will reduce up to 128,000 kgs of carbon emissions annually and save $95,000 annually in fuel costs. Not only did our evidence-based methodology result in a payback period of only 2.5 years, but it also contributed to achieving the company's overall sustainability goals.​

 

Project wins:

  • Excellent site team engagement
  • Quiet and continuous operations
  • Compact design
  • Performance data used for ESG compliance and strategic business decisions
