Constructing A ColossusCutting Carbon Using Greater ConnectionsGeopolitical Play Or Environmental Sense?The Changji-Guquan transmission line is a colossal feat that will be able to transmit 12,000MW of power, or enough to meet the needs of 26.5 million people, across China. It will transmit the same amount of power as Romania uses in a year, or half of Spain's energy demands, over a distance greater than Barcelona to Moscow as the crow flies.
