China will spend at least 2 trillion yuan (US$315 billion) to improve its power grid infrastructure over the 2015-2020 period, a report by a government newspaper said on Monday (31 August 2015). Despite falling power consumption growth, China is working to upgrade its cross-country power transmission capacity in order to reduce coal consumption along the smog-hit eastern coast and provide markets for energy producers in the resource-rich far west, where electricity demand is considerably weaker. It has already built long-distance ultra-high voltage power lines connecting giant thermal power and hydroelectric stations in the west to eastern coastal regions like Shanghai. The 2015-2020 investment is likely to provide a boost for sectors like copper. Demand from the power sector accounted for nearly half of China's estimated 8.7 million tonnes of refined copper consumption last year.
