SGIP Catalog of Standards (COS) (full-text).
“The CoS is a compendium of standards and practices considered to be relevant for the development and deployment of a robust and interoperable Smart Grid. The CoS may contain multiple entries that may accomplish the same goals and are functionally equivalent; similarly, a single CoS entry may contain optional elements that need not be included in all implementations. In general, compliance with a standard does not guarantee interoperability due to the reasons given above. Though standards facilitate interoperability, they rarely, if ever, cover all levels of agreement and configuration required in practice. As a part of its work program, the SGIP is defining a testing and certification program that may be applied to the equipment, devices, and systems built to the standards listed in the CoS and that, if applied, will substantiate that implementations designed to the respective standards not only have compliance with the standards, but are also interoperable with one another. The CoS entry indicates where test profiles are defined and testing organizations identified for a particular standard.”
