Producer
State Grid Corporation of China (SGCC)
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.
