r d plan

Research and innovation clusters: Smart grids and cooperation with DSOs play a major part in the R&D Plan, partly because of the balancing challenge

R&D Plan:

European Electricity Grid Initiative: Program budget - summary

  • Total program cost estimation is around € 2 bn in 9 years (2010 – 2018)
  • The cost estimation of the priority actions that need to start in 2010-2012 is around € 1 bn
  • The results are beneficial for the whole European energy value chain, requiring a comprehensive funding that must involve EC, the Member States, the regulators and industry.
entso e and cim

ENTSO-E needs and wants to have only one data exchange format

ENTSO-E organizes yearly Interoperability tests to ensure right and stable development

The Roadmap for the implementation of next updates of the ENTSO-E CIM Profile avoids frequent changes in the ENTSO-E CIM Profile


Current ENTSO-E CIM/XML Profile

  • Current ENTSO-E Profile is the profile tested in UCTE IOP in March 2009 in Paris. THIS IS THE PROFILE THAT MUST BE IMPLEMENTED BY ENTSO-E MEMBERS.Updates of this profile should follow the approved Roadmap
  • Proposals for changes are welcome and will be discussed within ENTSO-E, IEC and will be tested in the ENTSO-E IOP once agreed among IOP participants.
  • Current ENTSO-E CIM/XML profile is published on ENTSO-E web site (CIM part:
  • ENTSO-E Boundary Set is available here:
  • A draft version of the 2nd edition of the ENTSO-E CIM/XML profile was developed for the ENTSO-E interoperability test in July 2010. It is also available on the ENTSO-E web site (
roadmap for future implementation of cim
Roadmap for future implementation of CIM

The aim: to structure the implementation effort. No yearly implementation. An exception could be only if a change is introduced which is critical for ENTSO-E processes

The implementation process is foreseen to last one year.

On regular basis the implementation effort is foreseen every three years, if necessary.

Next versions of the ENTSO-E Profile have to be approved by System Development Committee (SDC). In case of changes that affect operational data, System Operations Committee (SOC) decision is also required.

SDC or SDC&SOC decision ensures one year implementation period. Coming into force date is fixed and mandatory for TSOs

EXAMPLE: if the updated version of the 2nd ENTSO-E Profile for IOP 2011 is OK:

Approval by SDC and SOC

2012 implementation year

Jan 2013 ENTSO-E switches to 2nd edition of the profile for all exchanges.

entso e iop 2011 test topics
ENTSO-E IOP 2011 – test topics
  • Interoperability using the last Unified Modeling Language (v15 + Dynamics + any modifications agreed among test participants) – new draft of the 2nd edition of the profile
  • Interoperability using 1stand 2nd editions of the profile, including naming convention
  • Model Authority Sets (MAS), file headers, model assembling process
  • Incremental exchange
  • Exchange of short-circuit data according to IEC 60909
  • Exchange of dynamic models (standard models, user-defined models, proprietary models) – Further developments in the part of dynamics are not expected due to lack of the time
  • Diagram layout – 61970-453; GIS data
  • Exchange “operations to planning” – The goal: detailed model to be exported to fit to ENTSO-E profile and imported by planning applications.
  • ENTSO-E Equipment profile is the 452 one. “operational to operational exchange can also be demonstrated”
cim extensions needed
CIM extensions needed

ENTSO-E IOP Report 2010

  • Finalized and published in mid August 2010
  • Available on the ENTSO-E web site:
  • Identified CIM issues were listed in the final report and submitted to IEC WG13 for further discussion. CIM15 resolves most of the issues

ENTSO-E exchanges in CIM – migration process to CIM

  • Two main ENTSO-E processes are subject to CIM migration
  • System development
    • Still in migration period.
    • First data exchanges in CIM started in February 2010.

“Planning exchanges” – required for TYNDP, regional initiatives, i.e. EU 3rd Energy Package

  • DACF process
    • The goal is to complete migration stage by the end of 2011
  • First test exchanges started on 8 June 2010 and finished in the end of August 2010
  • Now the second stage of tests for DACF is running. TSOs are exchanging 6 files per day in CIM (one day in a week) . The goal is to verify the procedures and test Communication channels.
  • TSOs are building their converters to CIM (operational systems to CIM)

Day-Ahead Congestion Forecast process – stable exchange needed to support system operation


ENTSO-E exchanges in CIM – migration process to CIM

Why after two successful IOPs (March 2009 and November 2009) the real interoperability with 1st edition of the ENTSO-E CIM profile is still a very difficult task?


ENTSO-E exchanges in CIM – Lessons learned

  • Testing with real data is necessary. IOP test cases cannot fully represent all modelling approaches
  • More complex test models are needed. The role of CIMug and IEC in test models preparation is to be discussed
  • Some vendors introduced post IOP changes which made real interoperability not possible.
  • More strict rules on interoperability are needed to ensure that commercial products are really fully compliant with the Profile
  • Intensive communication between vendors and users is necessary to ensure right modelling and usage of right tools
  • Vendors should demonstrate their readiness to support ENTSO-E Profile

ENTSO-E exchanges in CIM – What ENTSO-E is doing .....

  • To reach interoperability with 1st edition of the ENTSO-E Profile:
    • TSOs are kept informed on the efforts to be done: ENTSO-E Committees meetings, various workshops
  • Actions have been taken to improve communication between TSO and vendors
  • ENTSO-E Secretariat is contacting involved vendors on daily basis
  • To ensure future interoperability and improve business process:
    • ENTSO-E IOP 2011 will test both 1st and 2nd edition of the profile
    • Strict validation of the naming convention will be done during IOP 2011
    • Vendors will be asked to export test models that they already have and demonstrate interoperability
    • The 2nd edition of the profile is fully based on the 452, 456, 453, 552, etc. standards. Exchange flexibilities are improved. Open issues are clarified
    • ENTSO-E will implement a Network Modelling Database

Network Modelling Database – time schedule, objectives
  • Preparation work and ENTSO-E decisions in 2010
  • EU tender started in Dec 2010; offers assessment is ongoing
  • Contract expected in July 2011;
  • NMD fully operational Jan 2012.
  • Objectives:
  • To adapt ENTSO-E business process to an automatic CIM based data exchange
  • To have a system that supports the official ENTSO-E CIM profile and supports development of next editions of the profile. In Jan 2012 NMD should support 1st and the 2nd (July 2011) editions of the profile
  • Provide automatic model assembling functionalities based on the ENTSO-E CIM profile, i.e. MAS, boundary sets.
  • Allow users to maintain TSO, regional, pan-European models; store scenarios; import/export full, partial, differential files
  • Allow specific queries, etc.

Common CIM Tools used by TSOs

  • CIMdesk
    • Validation, visualization and editing tool developed by PowerInfo LLC, US
  • Provides users with possibilities for direct editing of CIM files and graphical visualization
  • It is not related to the migration process. It will be used and maintained as long as CIM /XML format is used
  • Maintenance contact has been prolonged. A re-licensing rules were agreed with ENTSO-E. Non ENTSO-E members can buy a license of CIMdesk. Requests should be addressed to PowerInfo LLC.
  • Migration converter
    • Developed by EDF R&D, FR
  • Converts from UCTE CIM to UCTE DEF (current version: version 02) and vice versa
  • To be used during the migration stage; useful only for DACF exchanges in the RG Continental Europe
  • Maintenance contract was prolonged until 31 Dec 2011.
