> Ultra-high voltage lines operate at voltages above 800 kV for direct current or 1,000 kV for alternating current,

Interesting, I thought above a certain distance DC is more viable. Or are they just describing the UHV term in general, not really that particular 700km line.

Ultra-high voltage is an industry term. See https://en.wikipedia.org/wiki/High_voltage#Definition

> ANSI C84.1-2020 defines high voltage as 115 kV to 230 kV, extra-high voltage as 345 kV to 765 kV, and ultra-high voltage as 1,100 kV.
