Three types of supplies : Aircraft, ground and GPU https://www.zurich-airport.com/~/media/flughafenzh/dokumente/das_unternehmen/laerm_politik_und_umwelt/luft/2018_zrh_aircraft-ground-energy-system_20180214.pdf OSM would only describe ground power supplies and obviously not mobile GPU precisely because they move. It's not so desirable to add power_supply=GPU on the airport perimeter or relation because you'll have to deald with electronic appliances charging supplies, industrial supplies or any other numerous kind of supplies in such a complex facility.
