Very few electric customers are served by more than one substation, that substation and the distribution wiring between the substation and the customer are going to be a SPOF, except for the few customers with access to multiple substations.
Some substations don't have redundant feeder power either, although that's more often the case where geography makes it difficult (islands/peninsulas)... But the mention of wiring on a bridge might be an indication that is a geographically difficult area of Berlin?

Most infrastructure is fragile and is one step away from going down. It basically can’t operate without the assumption that people won’t mess it up.
This. Infrastructure as does the whole society, relies on trust.
