- Use broadband over power lines to communicate with the power company. The power company tells the house a current price for electricity, and possibly what the guaranteed price will be over the next 24 hours.
- Appliances can decide for themselves the best time to run. For example you tell the dishwasher "I want the dishes cleaned by 8am" and then it finds the lowest-priced time to run.
- Of even more benefit to the power companies, you could negotiate with your power company a maximum power usage for your house of X amps. The power company would like to do this because they then know the maximum amount of power they need to plan for when building their infrastructure. Your home-controller would then be responsible for negotiating with your appliances a way to meet this power goal. For example, it may be necessary to shed some unecessary load at peak times (say during a heat wave) and it would be possible for the home controller to turn off whatever appliances are not needed at that time to keep you under your agreed-upon allotment.
