Tag:power=substation - OpenStreetMap Wiki:power=substationHow to Map. Tag a or a as power = substation.Most substations should be mapped as areas. Very small substations such as small transformer kiosks in residential areas may be mapped as substation nodes, or as transformers.. In a few cases, a single substation is split over multiple sites (for example on either side of a road), and should be tagged as a multipolygon relation.
