This article surveys the status of the international standards of CIM (Common Information Model). CIM is being focused from all power engineers, because the standards will contribute Smart Grid technologies largely. CIM defines the most promising information model to realize CDM (Canonical Data Model). However, task making the complete CDM for transmission EMS needs very large efforts, so that CIM is being on development stage. This Article reports usefulness of CIM and development status of international standards of CIM. Also, an example of utilization CIM, which is an outcome from the NEDO project entitled; Research for Promoting International Standardization on the Technology of Wide Area Situational Awareness (WASA) for Trunk Power System, is expressed.
