City of Leesburg Electric UtilityEarned the APPA Reliable Public Power Provider
designation 2006 and 2008 (valid for 2 years) Criteria: Reliability, Safety, Workforce Development, System Improvement
History of assisting other utilities:Homestead 1992: Hurricane AndrewMount Dora 1993: The Storm of the CenturyKey West 1998: Hurricane GeorgesNext?: We are prepared and willing to help

System Design & Hardening StandardsConstruction meets NESC 100 mph wind contour
Harden all new and replacement Feeder poles
Underground facilities along major arterials
Participate in Public Utility Research Center wind and overhead to underground research through FMEA
5
System Design & Hardening StandardsMinimal exposure to flooding and storm surge
located 60 miles inland
Facilities constructed along front lot lines
Ensure “foreign” utility attachment design standards and inspections

System Maintenance & Inspection8 Year inspection cycle for 16,500 poles
10,200 wood (62%) and 6,300 concrete (38%)
6,220 (38%) poles inspected during CY 2007 0.05% Priority reject poles (3 poles) 2.6% Failed minimum strength and replaced (160 poles)
1,300+ (8%) poles in be inspected May-June 2009

Pole Inspection BenefitsHistory of wood pole inspection & treatment since
1970s – poles installed during 1940s still in service
Wood pole inspection and treatment is cost effective 18-24” Excavation Plus Sound and Bore and Supplemental Treatment together with Visual
inspection will identify ≈ 98% of reject and priority poles. (Note 1) Recommended to repeat inspection every 6 to 10 years
External and Internal treat as needed to preserve remaining strength and prolong service life
Priority poles reported to utility each day and assigned to crew to replace
Inspector also replaces pole tags and guy markers, repairs pole ground, and reports observed safety hazards
Note 1 : Industry estimate

System Maintenance & InspectionVegetation management – 4 year trim cycle for
feeders and laterals (10 foot clearance)CY 2008 Vegetation outages
7 Outages (20%) caused 175,020 CMI (87%) 27 Outages (80%) caused 26,971 CMI (13%)
(CMI = Customer Minutes Interrupted)
Added 4th Tree Crew during 2008
Budget: $400,000 (8% of Distribution budget)

Early Preparation ActivitiesReview Lake County and City Storm Plans
Revise Electric Department Storm Plan, Plan Coordination meetings, Assignments, and Dry Run
Confirm local motel, restaurant agreements
Update Mutual Aid contact information
Confirm all employees completed appropriate National Incident Management System training
10
Annual Planning Activities“Prepare for the Worst… Hope for the Best”
Coordination involves the entire community:Verify material storm stock levelsConfirm Contracted ServicesElectric Department Initial Damage Assessment assignmentsAssist Public Works “First Push” to clear arterial roadwaysVerify additional communications equipment availabilityAssist Telecommunications utility repair damaged fiber facilitiesCoordinate and confirm Building Department repair permitConfirm retiree, utility construction and ROW clearing contractor
availability
11
Pre-Storm ActivitiesInitiate activities based on projected storm trackComplete Pre-storm department checklists and create
restoration work ordersPrepare mobile generators for deploymentComplete personal preparations and confirm personnel
assignmentsConfirm appropriate local motel, restaurant needsConfirm Local and FPSC reporting needs & scheduleMaintain restoration activities until wind gusts make work
unsafe (35 mph)“Hunker Down” or other appropriate activity
12
Post Storm Restoration ActivitiesPerform Initial Damage Assessments
Data sheet and picturesRequest additional resources or offer assistance to
others Prioritize initial restoration activities
Public safety and health facilitiesFeeders, portions of feeders, and priority laterals
Dispatch ROW & Distribution CrewsPrepare initial restoration forecastsMaintain accurate periodic reporting statisticsEnsure restoration activities are progressing without
labor, material, or equipment shortages13
Concerns & VulnerabilitiesWe surveyed our members for ideas Over-subscription of resources for restoration:
Workforce – Independent line crews and tree trimming crewsSupplies – PolesHousing – Hotel/motel rooms, with utilities reserving rooms 2-3 days
ahead, before storms approach Suggestion: Create ad hoc committee through ESF-12 at State
Emergency Operations Center with representatives from each investor-owned utility, and the municipal and cooperative associations to share information and needs as they arise during emergency events.
14
Concerns & VulnerabilitiesTransmission system vulnerability
Most municipal electric utilities are transmission dependent – they purchase power from other utilities and receive electricity via the high-voltage transmission system. The most storm-hardened local distribution can still go dark if a transmission line fails.
Keys Energy – Health care after evacuationsKeys are evacuated frequently, along with medical personnelKeys management is reluctant to allow lineworkers to work without an
active emergency room nearbyHave been working with Agency for Health Care Administration to keep
medical personnel in area (storm hardened facility), but to no availResult – restoration in Keys may be slower than expected
15
Concerns & VulnerabilitiesKeys Energy – Storm Hardening – Electric vs. Telecom
About 12,000 poles in Keys Energy service territory 9,000 owned by Keys Energy 3,000 owned by AT&T Poles are intermingled throughout system, and most are joint use
Keys Energy designs distribution system to NESC standard of 150 mph extreme wind load
Local communications company, AT&T, is not required to do soWhen AT&T replaces a pole, Keys Energy has agreed to pay incremental
cost from standard wood pole to storm-hardened concrete pole. AT&T continues to own pole.
Keys Energy asks “Is it fair that only they are required to pay the cost of storm hardening when facilities are so obviously intermingled and jointly used?”
Issue may exist elsewhere across Florida
