21 Superstorm Sandy Preparations 21

22 Storm Preparations: Guided by Corporate Coastal Storm Plan Plan triggered 5 days prior based on National Weather Service forecasts Reviewed 24/7 staffing plans Equipment vulnerability Inventories Protection plans for equipment in flood zones Need for outside assistance 22

23 Storm Preparations Restored as much out-of-service equipment as possible Installed sandbags and water dams to protect infrastructure Relocated personnel and supplies to higher ground Deployed thousands of personnel to work 24/7 23

24 Storm Preparations Communicated safety information through press releases, website updates, and blasts to 1.3 million customers Contacted lifesustaining equipment customers, and critical-care facilities to warn of possible service outages Secured initial deliveries of dry and wet ice in anticipation of significant customer outages 24

25 Storm Preparations Activated Logistics Operations Control Center (LOCC) Established Corporate Emergency Response Center (CERC) 25

26 Storm Preparations Staffed Liaison positions within State, County, City and local EOCs Worked with New York Independent System Operator to keep additional electric generating units online 26

27 Storm Preparations Mutual Assistance 4 days prior, began requesting mutual assistance 3 days prior, requested Edison Electric Institute (EEI) to expand our appeal for mutual assistance nationally 1 day prior, doubled number of resources requested Over 5,700 mutual assistance workers and contractors support restoration 27

28 Storm Preparations System Safety Electric System Took three electric networks in low-lying areas out of service to protect equipment and enable faster restoration Preemptively isolated primary feeders in 12 other networks 28

29 Storm Preparations System Safety Gas System Secured gas supply, prepared liquefied natural gas (LNG) facility, and shut down four gas regulator stations 29

30 Storm Preparations System Safety Steam System Preemptively isolated steam mains and shut down the East River generating plant Preemptively isolated 200 steam services 30

31 Impact 31

32 Impact Customer Outages Electric 907,444 Sandy 1,115,294 Sandy and Nor easter Steam 561 services 142 due to electric system issues in lower Manhattan 53 due to availability of steam system capacity 12 due to crane incident Approximately 30 miles of steam mains impacted Steam Plants Preemptive shutdown Remained in service Forced offline (surge) ~60 customers out above 42 nd Street ~500 customers out below 42 nd Street 42 nd Street Gas 391 services representing 4,257 customers Edgewater Park, Locust Point, City Island, Queens, and Westchester 32

57 Back-Office Support 57

58 Back-Office Support Preparation Phase Mutual Assistance Requests / Coordination Equipment Relocation Facility Evacuations Ensure sufficient stock of materials for restoration Public Affairs Press Releases Customer Ops Contact LSE, MEDH, and CLIC customers Activate DESR, LOCC, and GERC 58

59 Back-Office Support Storm Phase Monitor and report on storm status Prepare restoration plans Update outgoing messaging to customers as conditions warrant Continue communications with critical customers and officials Accommodate Storm Riders and mutual assistance crews 59

60 Back-Office Support Restoration Phase Assess damage to computer systems and expedite repairs Dispatch municipal liaisons Outage map updating Support staging area and base camp operations Customer outreach vans Call centers Dry ice distribution Obtain environmental variances Track restoration costs 60

61 Going Forward 61

62 Going Forward Regional Big Picture Reassess coastal flood zones Next generation of storm plans Improve evacuation plans Anticipate gasoline and other resource shortages Evaluate earlier and more extensive shutdown of key facilities, such as transportation, utilities, hospitals 62

63 Going Forward Regional Measures New building codes Raise critical equipment Review waterfront development Rebuild/retreat Real estate industry collaboration Army Corps of Engineers evaluating storm surge barriers 63

64 Going Forward Con Edison Measures Electric Overhead Electric Underground Gas Substations Steam Generating Stations 64

65 Causes of Service Interruptions Wind/Tree Damage to Con Edison Equipment 65

66 Causes of Service Interruptions Submersion of Con Edison Equipment Some equipment preemptively de-energized to minimize damage and expedite restoration Some equipment submerged while energized due to unprecedented storm surge defeating flood prevention measures 66

67 Causes of Service Interruptions Submersion of Customer Equipment Much equipment was submerged in an energized state Additional damage due to corrosion by salt water 67

68 Storm Hardening Philosophy Threat Wind/Tree Caused Damage Coastal Flooding / Storm Surge Approach Protect Infrastructure Harden Components Mitigate Impact Facilitate Restoration 68

69 Electric Overhead System Advanced Equipment Selective Undergrounding Reduce Segment Size Sacrificial Components Enhanced Technology 69

70 Gas Distribution System Tunnel Hardening Water Intrusion Management o Install two additional high flow rate pumps per tunnel o Install backup diesel generators Build Reinforced Concrete Head Houses o First Avenue o Ravenswood o Astoria o Hudson Avenue 70

71 Gas Distribution System Component Hardening Replace cast iron & bare steel in flood prone areas Install Float Check Valves Evaluate options for 62 regulator stations in flood zones Con Edison Developed Float Check Valve 71

72 Substations and Generating Stations Protect Infrastructure Establish new design flood elevation for each station Control flood waters Raise critical equipment Harden operating circuits 72

73 Substations and Generating Stations: Flood Risk at East River 73

74 Substations and Generating Stations: Protect Infrastructure Relay House Critical Panel Critical Panel New Pump Build Barriers Around Key Components Seal Panels and Conduits Install Marine Pumps 74

75 Substations and Generating Stations: Protect Infrastructure Sandy Water Mark 75

76 Substations and Generating Stations Elevate Critical Components Con Edison Designed Enclosure Lift 76

77 Transmission Substations: Flood Barriers Before After 77

78 Storm Hardening Benefits Reduce customer impact in flood zone networks Minimize preemptive feeder outages system-wide Faster restoration times for network shutdowns Reduce costs associated with damaged equipment 78

79 Fortifying the Future Review all options Collaborate with key stakeholders Continue to improve communications Remain focused on strengthening our systems to withstand extreme weather 79
