State Grid Corporation of China (Beijing; 100% state-owned; ~USD 500B revenue — world's largest utility by revenue) operates the power grid for 26 of China's 34 provinces/regions, transmitting electricity from coal-fired power plants and the Yangtze/Yellow River hydropower systems to industrial consumers. State Grid delivers electricity to China's aluminum smelters — which consume ~60% of global aluminum's total electricity demand (~700 TWh/year). The massive ultra-high-voltage (UHV) transmission lines built by State Grid carry hydropower from Sichuan and Yunnan provinces (Yangtze River tributaries, including Three Gorges Dam) to eastern aluminum smelting clusters. State Grid also manages electricity to China's chlor-alkali industry (world's largest, ~30% global capacity) and lithium processing operations in Sichuan, Qinghai, and Jiangxi. China's aluminum smelter electricity is predominantly coal-fired (~60-70% of Chinese aluminum electricity), making Chinese aluminum the most carbon-intensive in the world.

Codelco (100% Chilean state-owned; HQ Santiago; ~$15B revenue) is the world's largest copper producer and the operator of Chile's most iconic copper mines — Chuquicamata, El Teniente, and Andina — all in high-altitude Atacama Desert regions facing severe water stress. Codelco's mines collectively consume billions of liters of water per year from the Atacama's scarce freshwater resources (rivers, aquifers) that are simultaneously needed by indigenous communities (Atacameño people) and the Atacama's extreme-endemic ecosystem. Codelco is investing in seawater desalination and water recycling to reduce freshwater dependency under pressure from Chile's 2022 National Water Strategy and reformed Water Code, which tightened water rights allocation. Codelco's water sourcing decisions are intertwined with Chilean government policy — as a state-owned enterprise, Codelco's water use is both a commercial question and a public sovereignty question.

Rio Tinto (LSE/ASX: RIO; HQ London; ~$54B revenue) is the world's second-largest mining company and operator of Oyu Tolgoi, the world's largest undeveloped copper-gold deposit (Gobi Desert, Mongolia, ~66% ownership via Turquoise Hill Resources). Oyu Tolgoi's water supply — sourced from the Undai River in a semi-arid steppe ecosystem — has been the central community conflict issue between Rio Tinto and Mongolian herder communities since construction began. The Undai River watershed supports traditional Mongolian nomadic pastoralism; mine water use was seen as an existential threat to herder livelihoods. Rio Tinto reached a water-sharing agreement with the Mongolian government in 2015 but community tensions persist. Rio Tinto's Pilbara iron ore operations (Western Australia) are relatively dry-mined but face growing pressure on groundwater extraction from Aboriginal community rights claims.
