I presume that in the days of mainly coal powered generating stations that
excess electricity would be generated at night. You are not going to shut
down a coal powered fire station to then start it up again the next day.

However, with the move towards greater use of gas powered fire stations, I
imagine they can turn the power on and off pretty much at will.

The problem is not the fires, but the fact that you have to keep the
Alternators turning or they bed down into their bearings and you would
never get them started again.
