Ultra-High Voltage Direct Current (UHVDC) electricity transmission ought to be the stuff of pure science fiction.
More than a million volts carrying the equivalent of 12 large power stations worth of power down a single line? Such a feat should be unthinkable. But it’s here right now. Today. And since it’s installation 3 years ago, it has delivered more than 300 BILLION kilowatt hours of electricity from wind and solar farms in the North West of China to the industrial centres 3000km away in the East.
