ENTSO-E represents the European Transmission System
Operators
41 TSOs, 34 countries
534 million citizens served
305,000 km of transmission
lines
950 GW generation
3,300 TWh/year demand
440 TWh/year exchanges
ENTSO-E has a significant role in delivering
European energy and climate change objectives
Key activities set out in Regulation 714/2009 (on cross-border electricity
trade, part of the 3rd Internal Energy Market Package)
• Deliver network codes binding to all network users (Comitology)
• Ten-Year Network Development Plan “TYNDP”
• Enable internal market (“market coupling”)
• R&D Roadmap (fully included in EEGI – the SET Plan)
Through its members deliver the infrastructure to:
• Deliverable markets to function
• Secure energy supply
• Meet climate change objectives with RES
Drivers for pan-European grid development
Sustainability
• More renewables far
from loads
• New electricity uses
(mobility with
electricity, heat
pumps...)
Competitiveness /
Market integration
• Optimal resources
sharing
• More long distance
trans-European flows
Security of Supply
• Continuity of supply
of remote/isolated
areas
• Prevent large
disturbances
Milestones for European grid development
Time horizons addressed in the Network Codes:
 Year ahead: outage coordination (NC OPS), Forward Capacity Calculation (NC
FCA)
 Month ahead: Forward Capacity Calculation (NC FCA), Regional Operational
Security Assessment (current business needs)
 Week ahead: Regional Operational Security Assessment (NC OPS)
 Two days ahead: Capacity Calculation for D-1 market (NC CACM)
 Day ahead: Operational Security assessment, model corrections and assessment
of remedial actions (NC OPS), Capacity Calculation for Intraday market (NC
CACM)
 Intraday: Regional Operational Security Assessment (NC OPS)
 Updates for outage plans upon request by Outage planning agents
 Regional security assessment requires at least Common Grid Models for the
whole synchronous area

ENTSO-E and CIM - history
 2004-2006: TSOs identified the need for more detailed exchange;
thinking on improving data exchanges
 2007-2008: interactions with IEC and CIMug and decisions on
direction towards CIM
 2009: 1st profile for network model exchange; In parallel market
effort on CIM are increasing
 2009-2013:
Development process for profile 2 (current CGMES)
Series of interoperability tests
– to prove vendors‘ implementation of profile 1
- to valudate draft standards and support
development
 Dec 2013: Approval of teh Common Grid Model Exchange
Standard (CGMES)
Why CIM is important for TSOs and ENTSO-E?;
ENTSO-E legal obligations
 TYNDP development process requires consistent data
 Network codes require – Common Grid Model
 TSOs exchanges require HVDC, dynamics, operational level
details to be exchanged, etc.
 The data consistency between planning, operation, market
systems will be improved over time if a harmonized common
conceptual model is used
 Better common studies if a common data exchange
language available. Huge benefits for TSO cooperation
 More and more important to have frequent and reliable
exchange in the frame of system operation
Identified gaps/issues and relates measures

Description of profiles; rules

ENTSO-E will work with
OCL rules as much as
possible; clearer profiles
Vendors are not obliged to test
CIM exports/imports when
changing tool version

Standardisation is voluntary

CGMES approval
•
On 18 Dec 2013 ENTSO-E Assembly approved the Common Grid Model
Exchange Standard (CGMES) v.2.4.13.
•
CGMES is approved as a baseline data exchange standard for the EU
operational and market Network Codes
• CACM : Capacity Allocation an Congestion Management
• FCA : Forward Capacity Allocation
• OS : Operational Security
• OPS : Operational Planning & Scheduling
•
CGMES will also be used for system development studies data
exchanges including ENTSO-E Ten Year Network Development Plan
related studies
CGMES content
• CGMES is a superset of draft IEC standards to be issued for IEC CIM16
• CGMES was developed in the last 4 years and covers:
• Bus-branch and node-breaker representation
• Exchange of solved and unsolved load flow models
(combinations of equipment, topology, steady state hypothesis
and state variables profiles)
• Exchange of diagram layout
• Exchange of geographical location (GIS)
• Exchange of dynamics models
Significant update of transformer modeling was done and HVDC
representation was introduced
CGMES documentation
•
•
•
Main page on CIM – link
Version 2.3.13 is available here
Information on CGMES conformity process will be available here
The documentation includes the following:
• Main document – standard, which defines the framework and sets rules
• HTML documents – exported for each profile belonging to the CGMES.
Specific profile rules are defined in these documents
• HTML Enterprise Architect export – identical view of the UML model as in
EA
• RDFS export – RDF schema for each profile belonging to the CGMES
• XMI export – directly exported from EA; contains all profiles
• CGMES issue list – this list should be used to report issues on the CGMES.
Issues should be sent to cgmes@entsoe.eu
Activities related to CGMES implementation
CGMES Implementation Roadmap – internal
document which defines a series of projects and tasks
to implement CGMES and reach a stage when

ENTSO-E IOP site in the CIMug
ENTSO-E Conformity Assessment Program
 Under development – to be ready for IOP – July 2014
 Policy
 Test configurations – “golden” models
 Test procedures and clear assessment rules
 Simplified approach to be applied at first stage
Main stages:
 Vendor issues conformity declaration
 Vendor requests ENTSO-E Conformity Assessment
 ENTSO-E performs Conformity Assessment
 ENTSO-E issues an Opinion which is publicly available
 TSOs use tested tools (which have positive ENTSO-E
Opinion) in the data exchanges
