Yet again you do not understand what is involved in actually turning people off remotely and having to physically visit every single house to do so .
Scenario town of 10,000 gas users in danger of losing its supplies which can result in very dangerous explosive situations and if the town does go off every single house has to be visited twice with roads dug up to disconnect those they cannot get into ,
5,000 smart meter users that can be remotely disconnected with the vulnerable already on the register so they are known about and can be left on or turned back on afterwards if they have been missed.
5,000 dumb meter users that have to be PHYSICALLY visited to turn them off with all the man power involved .
So lets think who they will be turning off first to save the dangerous situation occurring and all the additional man power and services required to feed and provide heaters etc to .
By turning off the 5000 it can make it possible to keep half the town on or essential services such as hospitals etc and if the whole town still needs turned off it is far more manageable to visit 5000 house and not 10,000
And yes towns and districts of cities lose their gas supplies for various reasons several times a year.
