The Group of International Comparison

of Transmission System Operation Practices


With the objective to benchmark performance and exchange best practice on system operation
…with the Objective to Benchmark Performance and Exchange Best Practice on System Operation

Most important reasons for being a member

  • Performance Measures Database (> 50 data points)

  • Comparing with other TSOs (Benchmark Model)

  • Identification of peers (Company profiles / Activity Lists)

  • Learning from other TSOs (Best Practice)

  • Informal contacts and TSO Questionnaires (Networking)

  • Counter Benchmark to Regulatory Benchmark (Insurance policy)

For benchmark purposes a standard tso with five key system operation processes has been defined

Data collected annually since 2000 validated by kema verified by group

Example of data points:

All data are availableformembers


For each process two benchmark models have been developed
For each process, two benchmark models have been developed…

Environmental Factors(e.g. network size)

TSO Process

Results are consolidated and discussed in workshops

Annual workshops (hosted by member TSO)

  • Data is validated

  • Benchmark Results are discussed and validated

  • Member TSOs present reasons for their positions

  • Learning points are identified by TSOs

Work program 2009-2010 project

  • Consolidation of Database

  • Consolidation of Benchmark Models

  • Enhancement of Performance/Quality factor

  • Comparison of Security Standards

  • System Balancing under influence of dispersed generation (e.g. wind, solar)

  • Comparison of Congestion Management

The Group of International Comparison

All transmission system operators are welcome to join the group
… All Transmission System Operators are welcome to join the group

  • New 24 months project starts in 2009

  • The Fee for a project of a two years’ project is 11,700 Euro, including two workshops

  • Contracts include confidentiality agreements between members and between members and KEMA

  • A project website www.tso-comparison.com contains general project information and members onlypages with confidential project information (databases, benchmark models etc.)
