As I know physics, all these could cause low frequency interference, or even some relatively low voltage DC. Most people will not see any significant effects (except Aurora), but electric distribution equipment safety fuses are very sensitive, so very possible for them to detect false alarms and turn off power lines. Same problem with railways, as many still use 100years old low voltage signalling to control arrows/semaphores and other equipment - they could gather "air electricity" on long lines (wires and rails) and could happen malfunction. All modern equipment, approximately after 1960s, use galvanic isolation and high frequency signalling, which is immune to low frequency interference.
