Just to offer a counter-point, in my experience it's often that they are managed in big groups, and individual control is uncommon.
Quite often at the right time you'll see big swathes of lights turning off, sections of neighbourhoods, as far as you can see down a reasonably straight road, etc.
From what I understand, it's usually just a timeswitch in the circuit breaker box at the side of the road.
- _-___________-_ 7y agoHard to say; it could be time control or ripple control of relays at substations, which would explain neighbourhoods turning on/off at the same time. It's still not fully centralised, and the more "decentralised" (I cringe when I write that word these days) it gets, the cheaper it gets to provide an always-on supply to the lamp post.
