This document includes the comments and responses to inputs received regarding the Report to NIST on the Smart Grid Interoperability Standards Roadmap, prepared under contract by the Electric Power Research Institute (EPRI). Comments were solicited in a notice published in the Federal Register on June 30, 2009. This document contains all comments received as of July 30, 2009, the end of the comment period, as well as associated responses from the contractor team. EPRI also made corresponding revisions to its report to NIST. Submitted to NIST on August 10, 2009, the revised document, along with the original comments, will serve as resources as NIST progresses further in developing Release 1.0 of the NIST Smart Grid Interoperability Standards Framework, which is planned to be available in September 2009.
