SALT LAKE CITY, Utah – Rio Tinto has completed construction on a new 5-megawatt solar power plant at its Kennecott
copper operation in Utah.
The 12,800 solar panel power plant will be commissioned in coming weeks,
enabling Kennecott to reduce its operational emissions by 3,000 tonnes of carbon dioxide equivalent per
year.
The plant will serve as a pilot project with the goal of expanding Kennecott’s solar energy supply in
the future.
Shifting to sustainable energy solutions is a priority for Kennecott. The mine closed down its
coal-fired power plant in 2019, moving to electricity paired with renewable energy certificates. This resulted in a
65 percent reduction in its carbon footprint and the elimination of over 1 million tons of carbon dioxide output per
year.
Rio Tinto Kennecott Managing Director Nate Foster said: “Rio Tinto Kennecott has a key role
to play in supporting the energy transition. We supply U.S. companies with the copper and tellurium they need to
produce solar panels, wind turbines, and conductors. We also continue to take steps to further decarbonize our
business, from our battery electric vehicle trial to our renewable diesel trial and now to our very own solar
plant.”
The location of the 30-acre solar array was carefully selected to minimize visual and
environmental impacts. It is adjacent to other existing industrial operations, away from residential and commercial
zones, with earthen berms from the railway providing a visual barrier to most of the
installation.
