Rio Tinto Expands Solar Power at Kennecott Mine

• Rio Tinto boosts sustainability at Kennecott Copper Mine with a new 25-MW solar facility, elevating its solar capacity and slashing emissions. Green energy for a brighter future!

Rio Tinto Ltd has announced a plan to expand solar power capacity at its Kennecott Copper Mine in Utah by constructing a new 25-MW solar facility. This addition will complement an existing 5-MW solar site completed in 2023, raising the mine's total solar capacity to 30 MW. The new solar farm, covering 210 acres and featuring over 71,000 panels infused with tellurium produced by the mine, is expected to be operational by 2025.

The solar installations are projected to decrease Scope 2 emissions by approximately 6%. Since 2018, the Kennecott mine has successfully reduced its carbon emissions by over 80% by transitioning from coal-powered energy sources to renewable solutions, including solar energy and a shift to renewable diesel for its mining operations.

How will Rio Tinto's solar expansion impact emissions at the Kennecott Copper Mine?

• Emission Reduction Goals: The expansion of solar capacity at the Kennecott Copper Mine aligns with Rio Tinto's broader goal of achieving carbon neutrality by 2050. The additional 25-MW facility is expected to significantly contribute to this target.
• Impact on Operational Emissions: By increasing renewable energy sources, the mine will enhance its ability to offset power obtained from fossil fuels, further reducing its operational greenhouse gas emissions. The new solar farm will contribute to this reduction by providing cleaner energy for mine operations.
• Long-term Sustainability: Transitioning to more solar energy not only curtails emissions but also supports the mine’s long-term sustainability initiatives, demonstrating Rio Tinto's commitment to minimizing its environmental footprint.
• Renewable Energy Integration: The combined solar capacity of 30 MW will allow the Kennecott Copper Mine to better integrate renewable options with its existing power supply, leading to more reliable and cleaner energy usage.
• Local Environmental Benefits: The move to expand solar facilities at the mine is expected to have positive effects on the surrounding environment in Utah by reducing air pollutants associated with traditional energy sources, thus improving local air quality.
• Community Engagement and Job Creation: The construction and operation of the new solar facility is anticipated to create jobs and opportunities within the local community, fostering support for renewable energy initiatives and their benefits.
• Technological Advancements: The use of tellurium-infused solar panels, produced at Kennecott, highlights advancements in sustainable materials sourcing and showcases the mine’s role in the broader transition to renewable energy technologies.
• Financial Incentives: The implementation of these renewable energy projects may result in long-term financial benefits for Rio Tinto by reducing energy costs and safeguarding against volatility in fossil fuel prices.
• Regulatory Compliance: Expanding solar power capacity can help Rio Tinto comply with environmental regulations and standards aimed at reducing carbon emissions, potentially avoiding fines and promoting reputational benefits.
• Public and Investor Perception: By increasing its commitment to renewable energy, Rio Tinto enhances its reputation among stakeholders, investors, and the public as a responsible corporate citizen actively addressing climate change challenges.
• Future Expansion Potential: The successful implementation of the new solar facility may encourage further investments in renewable energy at the mine and potentially lead to additional expansions beyond the initial plans, solidifying the mine's role as a leader in sustainable mining practices.
