some states have utility managers who are competent enough to keep Windows off of their networks
Personally, I don't trust the utility managers, but I do trust the utility engineers. I trust then to keep the "business" side of the house from affecting the "operations" side. Otherwise they will quickly lose their jobs. Normally there is complete isolation of the "operations" network from the "business" network. However, in some cases there is information exported to the "business" computer networks. Some may get alarmed that there is some of the "operational" information available on the "business" networks or even on the Internet (<A HREF="http://www.caiso.com/SystemStatus.html" TITLE="caiso.com">for example</a caiso.com>). However, utility engineers are very careful that these interfaces are unidirectional. For instance it's typical to disconnect the TX conductor altogether to create a physical disconnect when exporting operational information.
