The problem is not in product design, but in its daily operations, is where the challenge is presented. Utilities and Consumers will have to find different paths, but both convergent and this will not be easy, alone, technology may not be able to establish or even bring the expected benefits.

The Utilities will have to show shareholders and consumers that the benefits outweigh the costs to gain approval for new investments. The modern grid can not exist without an effective integrated communications infrastructure, and also can not exist if there is the commitment of all its stakeholders -- Government, Utilities and Consumers.

Several communication technologies are presented daily in the market, but that instead of helping just bringing more uncertainties, and consumers know that the string always breaks toward the weaker, and weaker side is always the consumer.

The Utilities can recognize a good project for AMR and AMI and its integration with the area of IT, but using and sharing it with consumers, they have no idea. The HAN area must be taken now as a priority, because without its implementation, I do not see how we will develop Demand Response. Renewable Energy is also closely linked to the development of HAN and Demand Response.

"Area coverage, capacity and cost are three requirements, but are treated as one, because many solutions require the participation of three. Wireless solutions can meet these two requirements, but the costs of the third. For utilities that require both coverage large footprint, and capacity -- with broadband and real-time applications, cost becomes the tradeoff, that is, Can cost rise dramatically to satisfy the coverage and capacity required".

One of the differences between residential environments and commercial/industrial environments is the level of sophistication and customer participation that can be assumed in configuring premises networks to achieve interoperability of Smart Grid communications. Many homes have one or more data networks linking computers or consumer electronics devices. However, this does not reflect all consumers. Moreover, even in homes that have data networks, consumers may not have the expertise suitable rooms for configuring a home network or may not want to spend time or money setting up a machine as a clothes dryer to communicate through your home network.

It should be possible for consumers to get some kind of benefit of energy savings without the need they have a local area network or expertise in setting data networks.

In the end, what we can all do for the development and deployment of all segments of the Smart Grid is useful and can reach all the intended goals.
