Lightning strikes happen everywhere and can hit any object. When those objects are part of the infrastructure that provides us with utilities like electricity a single strike will indirectly hit thousands of people. A single direct hit on a substation can put thousands of homes in the dark (and in the heat, especially in summer). Prolonged black outs cause damage to frozen food and loss of productivity for offices of factories in the same area.
