How does something like this affect power grids?

I'm no expert in this sort of thing but my understanding is that
voltages are induced of long conductors such as the power grid with its
many miles of lines and oil or gas systems with its many miles of pipes.

These induced voltages can drive destructive currents in the
aforementioned systems.
