European Transmission System Operators (TSOs), Transmission Capacity Allocators (TCAs), Transmission Capacity Auction Offices and Market Management System (MMS) software providers are invited to participate in this 3rd interoperability test (IOP) to be carried out on the CIM extension for the electricity market (IEC 62325).

The test aims to demonstrate that the IEC 62325-451-3 standard satisfies the information requirements for the transmission capacity allocation and nomination process in the European style market profile. The test will assess the compliance of work carried out in IEC 62325-451-3 versus the business requirements defined by ENTSO-E’s capacity allocation and nomination process (ECAN).

The main objective is to determine whether current ENTSO-E compliant XML instances related to the eight different documents supporting the ECAN process can be processed using the XML Schema Definition (XSD) generated by the CIM.

To take part in the 3rd ENTSO-E IOP “CIM for the Electricity Market” please submit XML instances for each document supporting ENTSO-E’s ECAN process, in separate folders, by 15 August 2013 by email to: Please note that these XML instances should not contain confidential information, as the results of the IOP will be published on the ENTSO-E web site.
