Cat’s power transfer system test estimates up to 70 percent reduction in emissions

The world's largest copper producer, Codelco, has plans to test the Cat Dynamic Energy Transfer (DET) system with its fleet of diesel-electric haul trucks at the Radomiro Tomic Division. The innovative test is part of Codelco's commitment to carbonization and sustainability while reducing its carbon footprint through the use of innovative technologies and electrification solutions.

Cat's Dynamic Energy Transfer system

The Cat DET system features several integrated components: a power transfer module that converts power from the site's electrical source to the required voltage, an electrified rail system to transmit the power, and a machine-connection system to transfer power to the truck's drivetrain. This system transfers electricity directly to the machines while they are in motion, including both current and future battery-electric trucks. By utilizing Cat DET, the site will consume less fuel, reduce greenhouse gas emissions, and extend the life of the trucks' engines.
​
The pilot is scheduled to begin in the second quarter of 2026 in open-pit operations. The test, expected to last approximately one year, will involve Cat 798 AC trucks and the installation of rails on one of the ramps where the machines operate.
​
This project is a new step in Codelco's roadmap to promote the electrification of mining equipment with the goal of decarbonizing its operations. To achieve this, the company is actively promoting joint solutions with original equipment manufacturers (OEMs), research centers, and universities, both national and international, among other industry players.

Innovation and collaboration meet at Codelco's copper mining site 

"We are steadily advancing toward the mining of the future," says Felipe Lagno, Codelco's corporate manager of Innovation and Technology, who explains that, according to preliminary calculations, truck emissions could be reduced by between 60 percent and 70 percent. "We have the opportunity to reduce our environmental impact and extend the useful life of our trucks without compromising productivity. Every project linked to technological innovation brings us closer to our goal of being a cornerstone of sustainable development for Chile and the world," he adds.
​
"This pilot program is the result of an extensive collaboration between Codelco, Finning SA, and Caterpillar, and will allow Caterpillar to continue refining and improving the design and functionality of our Cat DET system, incorporating the voice of the customer," said Marc Cameron, senior vice president, Caterpillar. "Together, we are not only transforming the way fleets operate on-site, but also paving the way for a more sustainable tomorrow."
​
Cat dealer Finning SA will also contribute to the trial's success by assisting with the installation and maintenance of the Cat DET system.
​
"For Finning, this industrial trial — made possible thanks to the strategic alliance that Codelco has consolidated with us over the years — represents a significant opportunity to advance the integration of cutting-edge technologies in mining. It marks a milestone in driving innovation through sustainable practices and reinforces our commitment to environmental stewardship, with a view to the future," says Juan Pablo Amar, president of the distribution company.
