Ground doesn’t typically dissipate power, rather, power is dissipated in the circuit/load — so if you just hook a wire to ground, you’re dumping gobs of power into the wire. If you do this in your home (DON’T), best case it will trip the breaker, worst case it will melt and catch something on fire.
It’s easy enough to burn a kilowatt — just boil some water. But it’s entirely something else to burn megawatt, or yikes, gigawatt scale power.
Can they not route excess electricity into the ground?
No, unfortunately, you can’t.
