usbr.govWorld's Biggest Ultra-High Voltage Line Powers Up Across super fixed electrical transmission power steel structureJan 02, 2019 · (Bloomberg) -- State Grid Corp. of China has started up the worlds longest and most-powerful ultra-high voltage power line from its far northwest to the heavily populated east. The 1,100-kV direct-current Changji-to-Guquan project stretches 3,293 km (2,046 miles), the nations biggest electricity distributor said in a statement Wednesday.What is the cost structure of transmission and distribution?The cost structure for transmission and distribution is different than for power generation, since there is basically no fuel cost involved with operating transmission and distribution wires (and their associated balance-of-systems, like substations).See all results for this question
