Overview of Hurricane Sandy Hurricane Sandy caused widespread

damage along the East Coast

• Overall, more than 9 million customers lost power during the event

• While the New Jersey and New York coast lines were the hardest hit, there was significant impact to southeastern Pennsylvania

• The Pennsylvania Department of Transportation reported that more than 200 bridges and roads were closed because of downed trees, power lines and flooding,

7

Overview of Hurricane Sandy

In excess of 1.2M PECO customers lost power. Over 840,000 customers experienced a sustained outage and 465,000 were out of service concurrently at the storm peak.

Sandy was the most damaging storm in company history.

Sandy caused approximately 3,500 primary events, 90% more events than Hurricane Irene

8

Overview of Hurricane Sandy Over 4,700 employees and

contractors worked around-the-clock to repair damage and restore service

Workers from as far away as Louisiana, Mississippi, Florida, Tennessee and Kentucky, as well as ComEd and BGE crews, helped with the PECO effort

Safety, as always, is PECO’s highest priority. We worked closely with our local emergency responders and communicated with our customers regarding safety through multiple communications channels

Coordination between PECO and governmental entities was essential to our emergency response strategy

Preparation During the week of 10/22, PECO recognized the

potential of the storm and began developing a specific storm response strategy• Modeled on previous Hurricane responses, including

Irene of 2011• Work schedules and accommodations for essential staff

were put in place• Foreign crew resources were identified and secured• Operations sub-centers were opened and staffed• Materials and supplies were staged• The distribution system configuration was normalized• All IT system work was suspended and systems stabilized

On October 26 Governor Tom Corbett declared a state of emergency on October 26 to speed overall preparations• All travel limited to essential personnel only

9

10

Preparation Initiated Pre-Event Planning and Preparations Five Days Prior to Storm

• Held Pre-Event Conference Calls to Discuss Preparations and Planning

• Around the Clock Staffing Strategy was Organized• Mobilized 1,670 PECO Operations and Support Personnel

Secured More Than 3,030 Additional Personnel for Assistancewith Restoration and Tree Trimming

Conducted Interviews and Briefings with Media to Discuss Storm Preparations, Planning and Customer Outage Expectations

Conducted Outreach with Elected Officials and Local Governments• State Regulatory and Elected Officials• County 911 Centers Outreach and Staffing• Municipal and County Governments

11

Using Lessons Learned from Irene

Utilization of Established Hurricane Plan

• Utilized a 200 point plan produced as a result of Lessons Learned from Hurricane Irene

Advanced Planning Keys• Activated EOC (Emergency

Operation Center) on Thursday morning (10/25) and remained open through 11/16 for system restoration and recovery work

• Early identification and requests for external support.

12

Using Lessons Learned from Irene

Staging of Crews• Followed Sub Center model: Staffed

centers, mobilized storm kits and material, accommodation arrangements, etc.

• 240 Crews were on the ground and ready to mobilize before the storm hit

Communications to Employees• Media and communications positions

were double-staffed and followed protocol established during Irene.

13

Using Lessons Learned from Irene Road Closures

Dedicated External and Operations Coordinators, and up to 8 field teams. PECO cleared 305 roads (~200% over Irene)

Used new system event codes to accelerate ID and dispatch

Customer Communications Regarding Restorations Proactive outbound calls to most impacted customers Four On-Site Command Centers to provide face-to-face communications

opportunities and information sheets for customers in most impacted areas Launched website to provide customers with outage information on mobile

devices

Permitting for Foreign Crews PECO coordinated with PEMA, PENNDOT, the Governor’s Office and the

Turnpike Authorities, as well as officials in other states, to expedite the ability of crews to reach the PECO service territory and support restoration efforts

3,150 • Customers restored prior to ETR - 48.2%• ETR Reach - 68.9%• Service Level - 92.6%• PECO Field and Gas Mechanics/Foreman - 868• Foreign Crews/Contractors – 2,055• Tree Trimmers – 849• Office - 928

16

Sandy Outages and Restoration Specific Issues Impacting Restoration

• High winds resulting in down trees• Road closures• 40+ MPH winds that required crews to

stand down for 5 hours• Some localized flooding

Damage to Distribution System (as compared to Irene)• Cross Arms – 2,875 (+37%)• Fuses – 16,522 (+31%)• Poles – 750 (+141%)• Transformers – 390 (+57%)• Wire and Cable – 141 miles (+60%)

Responded to almost 2,600 police, fire and wire down jobs

Polling locations• Due to pending election on Teas. 11/6,

approximately 2,100 polling locations had to be verified to determine outage status, and expedite response as required.

17

Number and Percentage of Customers Restored

Restored within 24 hours of outage 524,000 62.4%

Restored within 48 hours of outage 678,468 80.6%

Restored within 72 hours of outage 764,801 90.8%

Restored within 7 days of outage 849,830 99.98%

Sandy Outages and Restoration

Customer Restoration Timeline

Restoration Strategy• Restore service to any affected substations/unit substations• Perform switching to re-route power to customers when possible• Restore power to critical care customers • Restore customers with attention given to circuits based on number of affected

customers – cut and run initially• Restore power to smaller neighborhoods and individual services

18

Lessons Learned from Sandy

A full review of our Hurricane Sandy preparations and response was conducted within departments and as an organization

Successes to be Replicated:• Pre-Planning and early activation set us up for success• Utility Mutual Assistance again played an essential role in ensuring our

ability to respond to the event - PECO joined S.E.E. after Irene• AMR meter pinging prevented approximately 6,100 truck rolls,

accelerating our restoration efforts by 2 to 3 days• Effective communications focused on safety • Our sourcing strategy fully met our needs - No significant material issues• Having ALM’s, Supervisors, and Asplundh at Sub-Centers was very

effective

19

Lessons Learned from Sandy

New Opportunities (Sandy Lessons learned, in conjunction with Emergency Preparedness Standardization Initiatives, through Exelon Utilities):

• ETR determination and communication strategy review• Sub-Center/Sub-Station process review• Sub-Center communications and dispatch capabilities review• Damage Assessment best practice review• More “seamless” sharing of Exelon resources

• Lock Out / Tag Out consistency between the 3 utilities• Ability to view circuit maps between companies• Electronic Work Packages• Enhanced utilization of GPS

• Further enhancements to Road Closure process• Expand use of social media • Further enhancing our Storm Center website

20

Lessons Learned from Sandy

Additional opportunities:- Electronic work packages

o GPS prints on CD or flash drive- Clarify and communicate the “sub-center” process

o Enhance sub-centers to be self-sufficient- Improve process for PECO material clean-up after work is

complete- Establish air card process- Lock Out / Tag Out for Annuitants- Create PECO service territory information booklet for

contractors and foreign crews
