  25. Responsibilities in the area of electricity

  26. Monitoring and imposition of electricity management Normal operation Monitoring (Swissgrid) No OSTRAL VEB Petition to FC Analysis of situation NES Yes

  27. OSTRAL Commission OSTRALservices Supply management Consumption management OSTRAL • Ordinance  Mandate to Association of Swiss Electricity Companies • OSTRAL: Organisation for Power Supply in Extraordinary Situations • Execution

  28. Division of regions for consumption management EC = electricity company • Region North East: (381 EC) • 13 OSTRAL sectors • 6 OSTRAL assigned EC Total: 738 EC • Region Center West: (192 EC) • 2 OSTRAL sub-regions • 14 OSTRAL sectors • 23 OSTRAL assigned EC • Region South West: (77 EC) • 7 OSTRAL sectors • 18 OSTRAL assigned EC • Region South East: (88 EC) • 6 OSTRAL sub-regions • 8 OSTRAL sectors • 31 OSTRAL assigned EC

  29. Supply Consumption Management measures 100 % X % Goal

  30. Prepared measures % shortage Disconnections from grid + rationing Rationing Usage Restrictions Appeals measures
