  "account": "Chile’s copper mines require more electricity per tonne of metal produced due to declining ore grades, which could strain the country’s power system as the industry transitions to electric mining operations. Copper grades decreased by a third from 0.93% in 2005 to 0.62% in 2024, while electricity intensity climbed by 68% to 5.16 MWh per tonne over the same period. This correlation between falling grades and rising electricity intensity does not establish causation. However, the relationship remains strong with a Pearson correlation of -0.91. Chile, being the world’s leading copper producer, must consider the electricity demands of future supply. According to Cochilco, electricity demand from copper mining is projected to increase by 20.2% to 33.2 TWh in 2034, while copper production is expected to rise by only 8.3% over the same period. The decline in grades implies a 50% increase in the ore burden required to produce the same amount of copper. The historical data indicates that declining grades act as a structural pressure on electricity requirements rather than as a standalone explanation for annual changes. However, other factors such as processing routes, recovery, mine configuration, water requirements, and the energy mix can also influence electricity consumption per tonne of copper. The electrification effect has made electricity intensity a more complicated measure of mining performance, as operations replace fossil fuel-powered activities with electrical systems. This shift may increase electricity consumption per tonne while potentially reducing total energy consumption and greenhouse-gas emissions. For Chile, this distinction has significant implications for future supply planning, as the electrical requirements of each additional tonne of copper become increasingly important.",
