efficiency of the system”.
But, the present uncertainty about standards is
slowing down the development of smart
Both agree that: appliances …
1. Pricing must provide incentives to manage energy use efficiently and enable
consumers to save money.
2. Communication Standards must be open, flexible, secure, and limited in number.
3. Consumer Choice & Privacy must be respected: the consumer is the decision maker!

1. livello
_____ _______
(avoid niche solutions)
Quinto _______
_____ livello
2. The cost of connectivity must have a very low impact on the industrial
cost of the appliance
3. The appliance must be free from protocol constraints
According to these assumptions, Indesit has developed a
communication technology that:
1. can be used by any household appliance equipped with a digital control
system;
2. is based on the electronic resources already present in the appliance
(no cost added);
3. allows to move the “communication node” from the appliance to an
external adaptor (smart plug)

Pacific Northwest National Lab (PNNL) has
Quarto _______

Quinto _______
_____ livello that can be installed in various consumer (household)
appliances.
The GFA controller senses the grid condition by
monitoring the frequency of the system and provides
automatic response in the time of disruption.
Therefore, the GFA controller can provide demand
response capability to household appliances like
refrigerators, air conditioners, water heaters, etc.
“The GFAC chip can temporarily shift
how smart appliances use power to
soften the blow for utilities during times
of peak demand on the grid.”
