China''s focus on UHV transmission is based on the fact that energy resources are far away from the load centers. The majority of the hydropower resources are in the west, and coal is in the northwest, but huge loadings are in the east and south. To reduce transmission losses to a manageable level, UHV transmission is a logical choice. As the State Grid Corporation of China announced at the 2009 International Conference on UHV Power Transmission in Beijing, China …
