You'd scream bloody murder if your power costs jumped because they needed to have multiple backup routes to connect everything. Similarly, you'd gripe if the power company turned off power for days at a time because they needed to work on something. If anyone is forcing the need to work on live wires its the customers.
You're not really familiar with how the grid works. When you're dumping a few million dollars to string a line out to a small town you're not going to pay for a second line. The jobs that the lineman do with live wires are safe if they are well trained, have good equipment and follow procedure. It's far cheaper and easier to get good people that can do this sort of job safely than it is to string a second line.
Maybe it has to do with geographical location...but the only time we have been instructed to have contractors work on live wire is in emergencies. In all other cases, you have to plan to have to do a switch over with minimal down time. The back up to the back doe snot always exist (smart grids are still new and only a handful of communities have them), but you can always set everything up so down time is minimal. If the goal is to have no down time, then so be it, but it's still a risky adventure that would make even the most experienced shake.
