There are areas of vulnerability, but also enormous advantages. Let me speak about the advantages first.
We saw in hurricane Sandy very strong evidence that the kind of connectivity that you're describing between meters and the grid operators can help speed the restoration of power in very important ways, because all of a sudden the grid operators have a map of which households are missing power and which are up and running. So when you think about where to send your power restoration crews, having this automated flow of information rather than having utility trucks drive around and eyeball where the lights are out, it's enormously efficient and very helpful in speeding power restoration. So the smart grid is helpful for grid resilience.
But as you point out, this kind of connectivity, wireless connectivity, cell connectivity, could provide means of inserting bad data, malware, that electric companies are very mindful of today, and they are building security against those kinds of intrusions. What we need to do is continue dialogue with industry to make sure that best practices are being applied across utilities, that there's a sharing of information between government and industry about the threat signatures that they need to be monitoring, and that we do whatever we can to build protection against these kinds of intrusions.
