Where the Smart Grid and Internet meet ...

Using the Public Internet - A Matter of Cost

It is not cost efficient for utilities (of any size) to duplicate the Internet, therefore they will have to peacefully coexist - customers will demand it and it is in the best interest of an integrated national grid. Where the line is between the Public Internet and the utility environment is a bit tricky. Some believe that a private neighborhood cellular or WiMAX infrastructure is that, private. While it is likely that significant portions of the traffic will traverse over the Public Internet. This begs the question of how much true private network is cost effective for utilities, and how much should be sent over the Public Internet. In the case of the Public Internet - what security and other considerations are appropriate.

The NIST recently published an interagency report on security and the smart grid. I helped drive a section that created a check list of trades to be investigated in this subject area. The three volume report has many parts. The relevant one to this topic is found in volume 3 in section 7.4.6.
