  1. Energy Charter Forum How to better protect energy networks from disruptions The role and importance of international cooperation Bratislava, Slovakia– 10nd of October 2014

  2. Plan of the presentation • GO15 • Overview on major events and theirconsequences • Power network Resilience • International cooperationbeetwenPGOs • Conclusion www.go15.org

  3. GO15 • Voluntary initiative of the world’s 16 largest Power Grid Operators (PGOs) • Representing together more than 70% of the world’s electricity demand • Providing electricity to 3.4 billion consumers on the 6 continents • Responsible for integration of • 2 518 GW of generation capacity into the grid, • Of which 21% is from renewable  energy sources. www.go15.org

  4. Key Statistics www.go15.org

  5. GO15 Cooperation www.go15.org

  6. GO15 members Vision & Objectives To be a leader and a catalyst in the transition of the electric power industry to the power grid of the 21st century. WG : Enhanced Security WG : SOS PGO www.go15.org

  7. Sandy – October 29, 2012 MAJOR EVENTS MAJOR CONSEQUENCES www.go15.org

  8. Hurricane Sandy Damage www.go15.org

  9. Katrina www.go15.org

  10. Storms Lothar and Martin France 1999 www.go15.org

  11. France 1999 damage - details French transmission network is about 100 000 km & 270000towers DamagedTowers and Poles: « 0,5%... But about 10% of the circuits wereaffected www.go15.org

  12. France 1999 damage - consequence s 184 “source” substations (transmission/distribution) could not besuppliedafter the events more than 5 days for some of them www.go15.org

  13. Power System resilience www.go15.org

  14. LT - End user Power security Fuel supply Generation Adequacy Transmission adequacy N-x redundancy Overhead/underground network Mean time to repair Regulated Monopoly Free market www.go15.org

  15. Cascading events and Blackouts • Simultaneous occurrence of multiple threats can destabilize power system • Power system operators trigger “DEFENCE PLAN” to return to stable state • Main measures to reduce and control the load • After stabilization (could be in blackout): activation of “RESTORATION PLAN” • Systematic approach for repowering lost load • In case of severe infrastructure damage: • Restoration can take days to weeks • Deployment of disaster recovery plan, coordination of operational teams, external contractors, consultation with public authorities, priority setting, communication. www.go15.org

  16. Resilience Definition www.go15.org

  17. France 1999 www.go15.org

  18. ROBUSTNESS Mechanicalupgradingpolicy 15B€ 2001 2017 After 1999 storms, a new “technical” law (2001) : 3 “legal” wind pressures are used - Normal wind (in-land) :570 Pa on conductors (+20%) (before 480) - Strongwind (someregions) : 640 Pa • Verystrongwind (coastline/river-crossing) : 720 Pa • “Anti-cascading” towers must beerectedevery 5 km to avoidbigcascadingfailures to allow quick restorationthanks to temporarylines (5 km long) With the goals:Continuity of the supply Restoration of the supply Security of the Public: www.go15.org

  19. RESOURCEFULNESS & RAPID RECOVERY Emergency restoration systems at RTE Catenary 400kV lines Team training Lindsey 400kV lines • Crisis management

  20. INTERNATIONAL COOPERATION BEETWEN PGOS www.go15.org

  21. Coordination for secure operation in Europe 1 November 2013 The European Awareness System www.go15.org

  22. How can GO15 contribute • A network of experts: • Sharing best practices on: • Prevention, increased grid resilience • Training and Crisis simulation exercises • Crisis management • Communication • Sharing lessons learned after incidents • Database with case studies on severe power system failures • Joint Crisis Simulation Exercises among neighboring Grid Operators • Emergency response: • Framework for mutual assistance • Crisis communication protocol www.go15.org

  23. Collaboration Framework for Mutual Assistance www.go15.org

  24. Conclusions • Resilience is on the agenda of GO15-members • Preventive measures are benchmarked, including costs assessments • Experience exchange is extremely important for low probability/high impact events. • Members agreed on a framework for mutual assistance. www.go15.org
