  1. TSO Comparison Group:Benchmarking System Operation processes for 22 International Transmission System Operators Bart Franken (KEMA Consulting) The Group of International Comparison of Transmission System Operation Practices

  2. The TSO Comparison Group consists of twenty-two globally distributed members… • REN (Portugal) • RWE (Germany) • (Saudi Electricity Company) • Southern China Power Grid (China) • Statnett SF (Norway) • SvenskaKraftnät (Sweden) • Swissgrid (Switzerland) • TenneT BV (Netherlands) • TransEnergie / Hydro Quebec (Canada) • Transpower (New Zealand) • CLP Power (Hong Kong) • Transpower (formerly) E.ON Netz (Germany) • ESB (Ireland) • Elia (Belgium) • ESKOM (South Africa) • EWA (Bahrain) • Landsnet (Iceland) • Fingrid Oyj (Finland) • National Grid Transco (UK) • PJM Interconnection (USA) • PSE (Poland) • Red Electrica de España SA The Group of International Comparison of Transmission System Operation Practices

  3. …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) The Group of International Comparison of Transmission System Operation Practices

  4. For Benchmark purposes a ‘standard TSO’ with five key System Operation processes has been defined.. System Operation The Group of International Comparison of Transmission System Operation Practices

  5. ..and a process which takes into account the remaining differences between TSOs The Group of International Comparison of Transmission System Operation Practices

  6. Data Collected annually since 2000,validated by KEMA, verified by group Example of data points: The Group of International Comparison of Transmission System Operation Practices All data are availableformembers

  7. For each process, two benchmark models have been developed… Environmental Factors(e.g. network size) TSO Process Input(staff, cost) Output(uniform) The Group of International Comparison of Transmission System Operation Practices

  8. ..Here, an example of one of the 10 benchmark models is shown Environmental FactorsEF1: Network Size (circuit ends, generators, interconnectors) EF2: PlannedOutages (Transmission and Generation) Operations Planning InputFTE Output(uniform) Model parameters basedonregression of TSO data The Group of International Comparison of Transmission System Operation Practices

  9. Which results in an assessmentfor each process for FTE and Cost Example of BenchmarkResults Details are availableformembers The Group of International Comparison of Transmission System Operation Practices

  10. Simultaneously differences between TSOs are being investigated… Part of ‘Activity List forOperations Planning process’ Share in IT costs Details are availableformembers The Group of International Comparison of Transmission System Operation Practices

  11. 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 The Group of International Comparison of Transmission System Operation Practices

  12. And summarized in management presentations Sum of fivebenchmarkresults Quality of System Operation(frequency, energynotsupplied, Voltage) The Group of International Comparison of Transmission System Operation Practices

  13. The TSO Comparison Group will continue their work in 2009… 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 of Transmission System Operation Practices

  14. … 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.)  please contact Bart Franken bart.franken@kema.com, or via www.tso-comparison.com.
