An afternoon fault on a 10kV line in the distribution grid plunged the municipalities of Centar and Karposh into darkness. The collateral damage: traffic lights were knocked out at multiple intersections, and the system "Safe City" - the surveillance network run by the Interior Ministry - was completely off the grid. When the technology depends on electricity, one weakened cable is enough to deliver a genuine absence. "Safe City" has been live since February 2026. Its functions include speed recording, red-light running detection, scanning for unregistered vehicles, and logging parking violations. In other words - when the system goes down, you get a few hours of "free-traffic" right in the city centre. Drivers, evidently, notice this fast. The police set up officers at the main intersections in manual mode. EVN deployed teams to isolate the fault and reroute the supply. In the end, the whole operation laid bare something the engineers already know but politicians would rather not say out loud - the "Safe City" system is only as solid as the grid that keeps it powered. The question nobody is asking out loud: if this much software and hardware infrastructure collapses from a single 10kV fault, what happens to "Safe City" on a day when EVN's whole grid in Centar goes down - say, in the next major storm? Safety isn't measured only in days without problems. It's measured in days when the system is supposed to be there, and isn't.
