NIST submitted five IEC Smart Grid security and interoperability standards to FERC for rulemaking. The following observations can be made:
-Ā No IEEE, ISA, or even NIST standards were provided to FERC.
-Ā Each of the five IEC standards has existing interoperability concerns. For example, two vendors can both conform to the standards and yet neither be interoperable with the other- that is not āplug and playā.
