How Is Codelco Revolutionizing Mining with Dynamic Energy Transfer Technology?
Codelco, Chile's state-owned copper giant, is setting new standards for mining electrification with an innovative approach that could transform how the industry addresses its carbon footprint. The Dynamic Energy Transfer (DET) system represents a significant leap forward in mining industry innovation technology, offering a practical pathway toward decarbonization while maintaining operational efficiency.
The Evolution of Mining Electrification
The mining industry faces mounting pressure to reduce emissions while maintaining productivity levels that support global demand for minerals. Traditional diesel-powered haul trucks, which form the backbone of mining operations worldwide, contribute significantly to mine-site emissions and operating costs.
Historically, mining companies have faced a challenging dilemma: continue using proven diesel technology despite environmental impacts, or invest in complete fleet replacement with emerging zero-emission alternatives that may present operational uncertainties.
This gap between current operations and future sustainability goals has created demand for intermediate solutions that can deliver immediate environmental benefits while supporting longer-term transition strategies.
What Makes Dynamic Energy Transfer Systems Groundbreaking?
The Codelco Dynamic Energy Transfer system represents an innovative approach to mining electrification by allowing heavy mining vehicles to receive power while in motion. Unlike traditional electrification methods that require complete infrastructure overhauls or fleet replacements, DET works with existing diesel-electric trucks.
The system consists of three integrated components working in harmony:
- Power conversion infrastructure that transforms electricity from the mine's power grid to appropriate voltage levels
- Electrified aluminum rail system installed along strategic sections of haul roads and ramps
- Vehicle-mounted outriggers that maintain continuous contact with the rails during operation
This configuration enables trucks to seamlessly transition between powered and unpowered sections without interrupting operations, maintaining productivity while reducing emissions.
According to preliminary calculations shared by Felipe Lagno, Codelco's corporate manager of innovation and technology, the technology could reduce truck emissions by an impressive 60-70% when implemented.

- Caterpillar: Delivers the core technology and system integration expertise
- Finning S.A.: Supports installation, maintenance, and operational aspects as Caterpillar's dealer
"This pilot program is the result of extensive collaboration between Codelco, Finning S.A. and Caterpillar, and will allow Caterpillar to continue refining and improving the design and functionality of our Cat DET system, incorporating customer feedback," explained Marc Cameron, senior vice president of Caterpillar.
The partnership leverages each organization's strengths to accelerate innovation while ensuring the technology addresses practical operational challenges. Juan Pablo Amar, president of Finning, characterized the trial as "a significant opportunity to advance the integration of cutting-edge technologies in mining," highlighting how their long-standing relationship with Codelco facilitates this pioneering work.
Technical Breakdown: How DET Systems Function in Mining Operations
The DET system creates electrified corridors along strategic sections of mine haul roads where energy consumption typically peaks, such as steep ramps. As trucks travel along these routes, the specialized outriggers mounted on the vehicles maintain continuous contact with the electrified rails.
Power Transfer Mechanics
The system works by establishing an electrical connection between the stationary infrastructure and moving vehicles. This connection allows power to flow directly to the truck's electric drive system while in motion, even on steep inclines where energy consumption typically peaks.
When a truck enters an electrified section, the outrigger automatically establishes contact with the rail system. Power flows through this connection directly to the truck's electric drive motors, either supplementing or replacing the diesel engine's contribution depending on operational requirements.
Technical Integration Points
The DET system integrates with existing mine infrastructure through:
- Power transfer modules that condition electricity from the mine's grid to appropriate voltage levels
- Conductive rail infrastructure strategically installed along high-energy-consumption routes
- Truck-mounted connection systems that interface with the vehicle's existing powertrain
This architecture allows for flexible implementation, as mines can prioritize electrification of sections where the environmental and operational benefits will be greatest, such as steep ramps where diesel engines operate under maximum load.
Why Radomiro Tomic Division Was Selected for the Pilot
Codelco's decision to implement the pilot at its Radomiro Tomic Division reflects strategic consideration of multiple factors that make the site ideal for testing this transformative technology.
The Radomiro Tomic operation, located in Chile's copper-rich Antofagasta Region, provides diverse terrain including significant elevation changes that create ideal conditions for evaluating the DET system's performance during high-energy-consumption operations like uphill hauling.
The pilot program follows a structured timeline:
- Planning and preparation (Current phase)
- Installation of rail infrastructure (Early 2026)
- System commissioning (Q2 2026)
- Operational testing (12-month duration)

- Decision on broader implementation (Late 2027)
The pilot will utilize three Cat 798 AC diesel-electric haul trucks equipped with specialized connection systems, with electrified rail sections installed on key ramps to maximize impact while limiting initial infrastructure investment.
What Environmental Impact Reductions Can Be Expected?
The environmental benefits of the DET system represent one of its most compelling advantages. According to a report from Mining.com, preliminary calculations suggest truck emissions could be reduced by between 60% and 70% through implementation of the technology.
These projections make the DET system an attractive option for mining companies seeking to balance operational requirements with environmental responsibilities. The system achieves these reductions through multiple mechanisms:
- Direct displacement of diesel consumption during operation on electrified sections
- Reduced engine operating hours under high-load conditions
- More efficient energy utilization through direct electrical power delivery
- Potential for renewable energy mining solutions into the power supply
Beyond emissions reduction, the system offers the additional environmental benefit of potentially extending equipment service life by decreasing cumulative engine operating hours under high-stress conditions, reducing the resource intensity of fleet replacement cycles.
Economic Analysis: The Business Case for Dynamic Energy Transfer
While environmental benefits drive much of the interest in the DET system, the technology also offers compelling economic advantages that strengthen its business case:
- Reduced fuel costs through partial electrification of haul truck operations
- Extended equipment life by decreasing engine operating hours under high-load conditions
- Improved productivity potential by maintaining consistent power during uphill hauls
- Staged implementation allowing gradual capital investment aligned with operational budgets
- Compatibility with existing fleets avoiding the capital expense of complete fleet replacement
These factors create a multi-faceted value proposition that complements the environmental benefits, making the technology appealing from both sustainability and economic perspectives.
The staged implementation approach allows mining companies to prioritize electrification in areas with maximum potential impact, such as steep ramps where fuel consumption is highest, optimizing the return on infrastructure investment.
