Twin Metals Minnesota announced August 12 it will build on its commitment to advancing the nation’s most sustainable and technologically advanced underground mining project by investing in the electrification of its mining and support vehicle fleets. Implementing battery electric vehicle technology is the latest effort by Twin Metals to reduce its project footprint and further minimize environmental impacts.

Converting the mine’s fleet from previously proposed diesel equipment to electric vehicles will allow Twin Metals to significantly reduce its onsite greenhouse gas emissions (GHG) by 65%. Additional benefits include a decrease in power requirements for underground ventilation and heating; a reduction in maintenance needs; noise reduction; and improved worker safety and air quality.

Twin Metals will be the first mine in the state of Minnesota to adopt battery-electric vehicle technology. The planned electric vehicle fleet represents nearly 100% of the mining and large support vehicles for the project. Twin Metals has not yet established contracts with specific battery-electric mining equipment vendors.

Today’s news follows the company’s 2019 announcement that it was shifting to dry stack tailings management in its proposed design. Dry stack and filtered tailings technology remove the need for a dam and is the most sustainable method used to store tailings. Dry stack was endorsed in a 2020 study by MiningWatch, Earthworks, International Council on Mining & Metals, and by more than 140 NGOs.

Turning Connected Vehicle Data Into Decisions That Matter

Fleet leaders have more data than ever, but turning that data into clear, actionable decisions remains a challenge. This white paper shows how leading organizations are using connected vehicle data to improve safety, reduce costs, and optimize fleet performance. Learn how to turn insight into action across your fleet.

Are You Tracking Your Fleet's True Total Cost of Ownership?

Bobit Business Media surveyed 190 fleet professionals and found that while most fleets are tracking costs, fragmented systems and data gaps are keeping true TCO visibility out of reach. With rising pressure to control spend in an increasingly volatile environment, the gap between what fleets think they know and what the data actually shows is wider than you might expect. See how your peers are managing costs today and where the industry still has room to improve.
