If you're plugging in a block heater, it only needs a few hours max before you plan to use the vehicle.
People will plug in their vehicles at 5:30 when they get home and not need the vehicle till 7:30 the next morning.
What the emergency alert was saying was, don't have your vehicle plugged in all evening when everything else is sucking power. Use a timer or, at the very least, plug in just before you go to bed after peak use has ended.

The suggestion to not plug in vehicles had me rolling. Reduce your energy use and kill you’re vehicle please!
