Cool! Which led me further down the rabbit hole: https://en.m.wikipedia.org/wiki/High-voltage_direct_current

- HVDC uses voltages between 100 kV and 1,500 kV.

- HVDC can be cheaper for 500+ mile runs

- HVDC allows power transmission between unsynchronized AC transmission systems

- Recent advances make UHVDC feasible (800kV+)
