How Cummins Is Scaling Hybrid Haulage Across the Globe

Hybrid haulage has moved from possibility to proof. Through close collaboration among Cummins, Komatsu and mine operators, the Cummins hybrid-electric retrofit system, enabled by First Mode engineering, is demonstrating how hybrid technology can improve haulage performance while reducing fuel consumption and emissions, without requiring new charging infrastructure or major operational changes.

With field deployment underway at the Caserones copper mine in northern Chile, the conversation is beginning to shift. The question is no longer whether hybrid-electric haulage can work in mining. The focus now is how quickly the industry can scale the technology and realize its benefits across a broader range of operations.

That shift matters. Mining companies are continually looking for ways to improve productivity, control costs and maximize the value of existing assets, while also advancing their emissions-reduction goals. The industry needs solutions that deliver operational benefits within today’s operating realities, rather than depending on future infrastructure. Hybrid haulage is emerging as a practical pathway, helping mines improve performance and fuel efficiency while reducing emissions within the operational ecosystem they already rely on.

What Early Deployments Have Demonstrated

The deployment at Caserones, conducted in partnership with Komatsu and the mine operator, was intended to validate whether hybrid-electric haulage could deliver measurable results in a working mine while integrating seamlessly into day-to-day operations.

Early results have reinforced what operators care about most: performance, reliability, and simplicity. The system maintains a familiar operating experience while capturing and reusing energy that would otherwise be lost during braking and downhill operation. Its modular architecture is designed to enhance resiliency, allowing the truck to continue operating even if one battery string requires maintenance.

Field data from Caserones is tracking at or above expectations, with measured field performance closely aligned with the performance models validated at Cummins’ proving grounds in Washington State. The system has also demonstrated engine load reductions, creating the potential for extended engine life and lower long-term operating costs.

Just as importantly, the deployment has validated performance in one of mining's most challenging environments. Located high in the Andes Mountains, Caserones features steep haul routes, significant elevation changes, and demanding operating conditions that place constant stress on haulage equipment. Success under these conditions provides valuable insight into how hybrid technology can perform across a broad range of mining applications.

Scaling Beyond the Pilot Phase

Demonstrating technology in the field is only the beginning. Turning innovation into a commercially successful mining solution requires multiple capabilities to advance together: technical readiness, commercial maturity, manufacturing and supply chain capability, and operational support.

This is where many emerging technologies face their greatest challenge. Building a scalable product requires much more than engineering excellence. It demands a robust supply chain, trained service personnel, reliable parts availability, a clear commercial model and the operational capabilities needed to support customers over the life of the product.

Cummins and Komatsu are tackling this challenge together, leveraging the engineering and global distribution capabilities of both parties to advance technical readiness, commercial maturity, and operational support. This collaboration includes the development of training programs, service infrastructure, parts distribution networks, and channel partner readiness to support long-term adoption and customer success.

Ultimately, sustained industry impact will depend not only on the performance of the technology itself, but on the ability to deliver, service, and support it at scale.

A Practical Pathway for Global Mining Operations

The appeal of hybrid haulage extends well beyond any single mine site or region. Unlike many alternative decarbonization pathways, the Hybrid-Electric Retrofit System requires no charging infrastructure, no hydrogen supply, and no significant changes to existing mine operations.

This flexibility makes the technology particularly relevant for sites where infrastructure limitations, operational requirements, or geographic challenges make full battery-electric deployment difficult in the near term. Rather than waiting for future energy ecosystems to mature, mines can pursue measurable reductions in fuel use and emissions using assets already operating in their fleets.

For many operators, hybrid technology can serve as a practical bridge between today's diesel-powered operations and the low-carbon mine of the future, providing immediate benefits while preserving flexibility for future technology decisions.

Why Early Engagement Matters

Cummins' next-generation hybrid system is being designed to deliver even greater capability, including more than 1 megawatt of power output, active self-charging functionality, power boost capability that could improve cycle times by 3-9%, and operation at elevations exceeding 5,000 meters.

For mining companies, early engagement offers more than access to new technology. It creates an opportunity to help inform product development, evaluate integration within existing operations, and begin the change management process ahead of broader fleet adoption.

Hybrid haulage is no longer a concept awaiting validation. It is already operating in commercial mining environments and generating valuable real-world experience. As Cummins advances the next generation of the platform in collaboration with Komatsu and mine operators, the focus is shifting from proving the technology to scaling it. For mining companies seeking practical pathways to improve productivity, reduce fuel consumption and lower emissions, that future is no longer theoretical. It is beginning to take shape today.
