  1. Meeting EFET - BFE - ETRANS Status ETRANS / swissgrid Thomas TillwicksCOO Commercial Grid Management Monday, 21st March 2005Airport Conference Center, Zurich-Airport

  2. Agenda • Activities and developments 2004/05 • ETRANS activities • Status of setting up swissgrid

  3. Activites and developments 2004/05 • Co-ordination between ETRANS an GRTN further intensified. • Intensive co-operation between the TSOs of Italy and the countries at the Northern Italian border (France, Switzerland, Austria, Slovenia) regarding cross-border items. • New 380 kV double circuit line between Switzerland and Italy in operation since January 2005. • Experience of new congestion at the Northern border of Switzerland and in Germany.

  4. Congestions in Southern Germany Key points of the latest developments: • Reduced exports of France to Italy, Switzerland during last weeks • France temporary import country (from Germany and Switzerland) • Reasons: low temperatures and the use of electrical heating systems • Germany limits its exports to France: 5600 MW till 1.1.2005. • Since 19.2.2005 Germany reduces programmes to France. • Result: increase of programmes to Switzerland by 1000 MW. • Germany announces at 1.3.2005 a limit of export-programmes to Switzerland of 3000 MW. Since 5.3.2005 reductions take place. • Programmes between Austria and Switzerland increase by 250 MW to 500 MW. Physical flows exceed programmes by more than 1000 MW and are close to the physical limits. • Programmes to Italy are lower than the NTC values. 1.

  11. CH Need of accurate load flow forecasts (DACF) Concepts of DACF: Forecast based onpower plant-schedules Forecast based on import/exportschedules Results depend on quality of input data

  12. Summary • NTC values are schedules and not physical flows. • NTC values are chiefly determined by the generation pattern and the network topology – that can change each hour. • The NTC determination must be performed in coordination with one’s neighbouring countries. • The NTC determination lies at the crossroads between electricity trading and network security (risk management, firm or not firm values ?) • The available NTC forecasts are only very rough because the NTC values can only be checked after the electricity market close (chicken or egg problem)

  13. Agenda • Activities and developments 2004/05 • ETRANS activities • Status of setting up swissgrid

  14. swissgrid the TSO of Switzerland • Responsible for the operation of the Swiss transmission network • Operates one control area in Switzerland • Responsible for the management of cross border schedules • Responsible for cross border congestion management • Represents Switzerland in ETSO and UTCE swissgrid Transmission System Operator

  19. EleG • Art. 18b (neu) • 1 Der Übertragungsnetzbetreiber hat folgende Aufgaben: • Er betreibt und überwacht das gesamtschweizerische Übertragungsnetz und gewährleistet einen sicheren, leistungsfähigen und effizienten Betrieb. Er hat die Verantwortung für die Planung und Kontrolle des gesamten Übertragungsnetzes. • Er stellt die Systemdienstleistungen einschliesslich Bereitstellung von Regelenergie sicher. Die zu diesem Zweck benötigten Kraftwerkskapazitäten sind nach transparenten und diskriminierungsfreien Verfahren zu beschaffen. • Bei Gefährdung des stabilen Netzbetriebs ordnet er die notwendigen Massnahmen an. Er regelt die Einzelheiten mit den Kraftwerksbetreibern, den Netzbetreibern und weiteren Beteiligten. • Er erarbeitet transparente und diskriminierungsfreie Verfahren zur Handhabung von Engpässen. • Er arbeitet mit den ausländischen Übertragungsnetzbetreibern zusammen und vertritt die Interessen der Schweiz in den entsprechenden Gremien. • Er erarbeitet die technischen und betrieblichen Mindestanforderungen für den Netzbetrieb. Er berücksichtigt dabei internationale Normen und Empfehlungen anerkannter Fachorganisationen. • Er stellt die für die Netznutzung nötigen Informationen leicht zugänglich bereit und veröffentlicht die Netznutzungsentgelte, die technischen und betrieblichen Mindestanforderungen sowie die Jahresrechnungen. • Er erstellt Mehrjahrespläne zur Gewährleistung eines sicheren, leistungsfähigen und effizienten Netzes. • Er orientiert die ElCom jährlich über den Betrieb und die Belastung der Netze sowie über ausserordentliche Ereignisse. • 2 Der Bundesrat kann dem Übertragungsnetzbetreiber weitere Aufgaben übertragen. § Guidelines for swissgrid by law EleG ... planning ... operation ... monitoring ... of the CH-transmission network...

  20. Status of setting up swissgrid 1/3 • December 2004: • swissgrid legally founded • Not allowed to become operational due to the investigation of the Swiss Competition Authority (WEKO) • Enlargement of the ETRANS management structure in line with future structure of swissgrid • Since December 2004: • Work on setting up swissgrid continues without delay during WEKO-investigation: • Contractual framework between swissgrid and actual grid operators • Concepts and business processes for future swissgrid activities (schedule management, program responsibilities, congestion management, ….)

  21. Status of setting up swissgrid 2/3 • 17 March 2005: • WEKO agrees to merge the transmission system operation in Switzerland into swissgrid under conditions: • Obligation to allow discriminatory grid access for third parties • Obligation to publish grid use tariffs • Separate accounting for swissgrid and its shareholders • Swissgrid is not allowed to produce or to trade with electricity except for fulfilling its tasks or to hold shares at such companies • Obligations for swissgrid’s management and supervisory board

  22. Status of setting up swissgrid 3/3 • Future steps: • Founding companies to check the WEKO conditions • ETRANS to work further on needed business concepts for swissgrid • Start of implementation projects for new business processes • Establishment of necessary contractual framework between swissgrid and current grid operators • Nomination of swissgrid’s supervisory board • Transfer of responsibilities to swissgrid • Transfer of man power and activities from ETRANS to swissgrid • …

  23. Our goal Swissgrid to become operational and a fully recognized TSO in Europe
