It's vastly more expensive to put cables underground, and high voltage cables underground is in the realm of Bad Ideas because you're putting a high voltage physically near the electrical ground (the earth's crust), which adds cost, reduces reliability, and poses a serious danger to all living things near the line.
Sure, there may be exceptions that might make it worth while. However, if long distance high voltage underground wires was practical and cheap, you would see deployed much more often.
- fc417fc802 1y ago> poses a serious danger to all living things near the line That is always the case for the various failure modes of any high voltage line (and all the related equipment). That said, you have it exactly backwards. Above ground lines are much easier to inadvertently come into contact with. Once faulted the breaker trips within a matter of milliseconds. It's the initial contact that's deadly.
