This technical specification on the CGMES defines the main rules and requirements related to the CGMES which are mandatory for achieving interoperability with the CGMES and for 
satisfying business processes. In this document requirements are indicated as such in a 
tabular format. Some descriptions are merely used for clarification and are marked 
“Informational”. 
The profiles which belong to CGMES are defined in IEC 61970-600-2:2017. The related 
technical information and documentation (i.e. RDFS, OCL, XMI and HTML) needed for the 
implementation of the CGMES, which is not copyrighted by either IEC or CENELEC, is 
available at the ENTSO-E web site. 
The CGMES is defined using information on the Common Information Model (CIM) available 
in the public domain. 
Future editions of this technical specification will be released to describe following CGMES versions which will reflect additional requirements due to European network codes or 
guidelines.dition 1.0 2017-07 TECHNICAL SPECIFICATION colour inside Energy management system application program interface (EMS-API) – Part 600-1: Common Grid Model Exchange Specification (CGMES) – Structure and rules IEC TS 61970-600-1:2017-07(en) THIS PUBLICATION IS COPYRIGHT PROTECTED Copyright ？ 2017 IEC, Geneva, Switzerland All rights reserved.
