That used to be the case... but not true anymore. EPA regs forced many of the NG power pumping stations off-line, to be replaced by electric pumping stations. Don't believe me, look at the Texas ice-storm/blackout several years back. People with NG heat assumed they would be ok as long as they had enough juice to power the blower and control board on their furnace. That was the rude awakening that when the power goes out, so does the natural gas...
Exactly. Plus distribution has to be controlled. The controls are electric.
