Codelco has announced it plans to test Caterpillar’s Dynamic Energy Transfer (DET) system with its fleet of diesel-electric haul trucks at the Radomiro Tomic Division in Chile.
The DET system trial will include three diesel-electric haul trucks. Preliminary estimates indicate that these machines could reduce emissions by 60 to 70 per cent, as well as extend the lifespan of the trucks’ engines.
“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 of Caterpillar.
“Together, we are not only transforming the way fleets operate on-site but also paving the way for a more sustainable tomorrow.”
This initiative is part of Codelco’s commitment to decarbonization by reducing its carbon footprint through the use of innovative technologies and electrification solutions.
The Cat DET system is comprised of 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.
“We are steadily advancing toward the mining of the future,” said Felipe Lagno, Codelco’s Corporate Manager of Innovation and Technology.
“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.”
The pilot is scheduled to begin in the second quarter of 2026 in open-pit operations. The test, expected to last about one year, will involve Cat 798 AC trucks and the installation of rails on one of the ramps where the machines operate.
Cat dealer Finning SA will also contribute to the success of the trial 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,” said Juan Pablo Amar, President of Finning SA.
“It marks a milestone in driving innovation through sustainable practices and reinforces our commitment to environmental stewardship, with a view to the future.”
This project is a new step in Codelco’s roadmap to promote electrification. To achieve this, the company is actively promoting joint solutions with original equipment manufacturers (OEMs), research centres and universities, both national and international.
