Man. This smells of techie overkill. The utility can make an announcement via radio or broadcast or sms to let you know if the supply is under pressure. Then switch off non essential appliances normally.

I live in a country with a struggling national power grid as people have come online faster than the utility could service old and build new powerstations. The blackouts or load shedding are not as frequent as a decade ago but we've learned to live energy cheap.

Peak and off-peak pricing already exists in many places. Power consumption naturally fluctuates pretty wildly. It is very difficult to make any large scale system that is highly efficient at both 100% capacity and 50% capacity.
