“ABB has been aligned with our commitments to develop our mining operations in a way that fits with energy conservation and emissions reduction goals.”

Copper Mountain mine near Princeton, British Columbia is the mining company’s flagship site. It is a conventional open-pit, truck and shovel operation which produces approximately 100 million pounds (45,000 metric tons) of copper equivalent per year.


  • Help Copper Mountain reduce carbon intensity by more than 50 percent in medium term with a final target of zero by 2035.


  • ABB provided a trolley assist solution for mining haul trucks, including the design of the overhead catenary system (OCS) infrastructure and a rectifier substation providing in excess of 12MW of DC power.  


  • The trolley system has cut carbon emissions of the trucks by 90% on the trolley segment, paving a solid foundation to achieve the Company’s sustainability targets.
  • Trucks run with x2 speed increase, ensuring higher performance.
“The trolley assist infrastructure is an essential part of our plans to reach our bold medium to long-term targets. We trust their expertise and have achieved past successes together.”

Seamless integration and monitoring of trolley operations and energy consumption

The installation combines ABB’s electrification and automation expertise in the mining industry.

Each truck is fitted with a pantograph to receive external electric power. ABB was responsible for the off-truck trolley assist infrastructure and provided engineering, project management, equipment supply, system commissioning and construction management. ABB designed the overhead catenary system (OCS) infrastructure and delivered a rectifier substation providing in excess of 12MW of DC power to the trolley assist system.
The trolley control system is connected to the existing ABB AbilityTM System 800xA distributed control system (DCS) automation platform to seamlessly integrate and monitor trolley operations and energy consumption. ABB is also providing OCS components customized for mining applications.

Proven expertise from feasibility studies to full deployment

ABB collaborates with mining companies from initial feasibility studies through to full deployment. ABB has previously installed a similar substation at Boliden AB’s Aitik mine, Sweden's largest open-pit copper mine and is part of ongoing expansion plans at the site. This included a 4.8 megawatt rectifier, connected to the ABB Ability System 800xA control system.
