Smart appliances and smart electrical meters with in-home control and 
monitoring panels are already a reality. Our local utility is developing some 
prototype test circuits in a limited number of communities. They just installed 
a smart meter on my house. It can communicate with a control center and 
ultimately with appliances in my house and a control panel. It will bill 
electricity at different rates depending o the time of day (cheaper at night of 
course). In conjunction with the control panel,, it can determine when 
appliances should turn on and shut off. That mans laundry and dishwashing can 
be done in the middle of the night when rates are lower. Standby electronics 
can be switched off  at certain times of the day and automatically restarted at 
programmed times. It will also enable the power company to know when and where 
a failure has occurred. And the network control center will sometimes be able 
to reroute electricity around the failure.
