China surpassed the United States in electric power generation and consumption as of 2011. The State Grid Corporation of China (SGCC) is now the largest electric utility company in the world. The 2015 revenue of SGCC was US$329.6 billion, roughly 14 times of the 2015 revenue (US$23.5 billion) of Duke Energy, the largest electric utility in the United States. China’s enormous electric power industry started from an extremely small basis more than six decades ago. From 1949 to 2015, annual power generation in China increased by more than a thousand times, from 4.3 to 5740 terawatts-hours (CEC, 2016).
