    UHV Power Transmission
    “West-to-east power transmission project” signifies the energy transmission from the resource-rich western provinces, especially coal and hydropower resources, to eastern coastal regions in shortage of electricity power by means of power transmission.
    The coal occurrences in China are mainly distributed in the western and northern regions, hydropower in the southwest, while the eastern regions with heavy electricity load are scarce in primary energy. The decoupling relationship between electricity consumption and resource distribution calls for the “west-to-east power transmission” project.
    Among all key projects of Western Development Strategy, this project has the largest quantities and investment with the total investment exceed RMB 520 billion during the decade from 2001 to 2010. The implementation of this project will be conducive to transforming western region’s advantage in resources into that in economic, reducing environment burden as well as transportation cost, which is of great significance for the optimization of resource allocation and energy structure, and sustainable development of China's social economy.
