Wind masts and towers that are taller than 10 meters (33 ft) tend to attract lightning strikes during their technical lifetime even in areas with low lightning density. In areas with high lightning density, dozens of strikes per year are possible.

A lightning protection system with a low impedance ground electrode is feasible even when local safety grounding is not mandatory, for example on a solar-powered site.
