Introduction & Opening Remarks

Hurricanes of 2004 & 2005 highlight the need for a fresh look at these issues

We support this effort and will be active participants

Help shape infrastructure strategy that works for Florida

Be clear what we’re trying to improve; make sure any change is for the better

2004 Hurricane Season – Distribution and Transmission Equipment Repaired

• Distribution– 10,379 FPL poles– 960 miles of OH conductor– 590 miles of OH service conductor– 1 million OH splices– 30 miles of UG cable– 100 miles of UG service cable

• Transmission / Substation– 174 structures– 15 miles of conductor– 3 substation transformers– 10 regulators– 39 breakers

5

Lessons Learned from 2004• Hired 3rd party consultant to help evaluate system

performance and restoration processes– Key findings

FPL met or exceeded standard utility restoration practices

FPL’s distribution, transmission, & substation facilities performed well

FPL’s transmission system was restored effectively

– Areas of opportunity Enhance customer communications by providing lower level ETR’s

Establish critical infrastructure priorities with local EOC’s

Establish partnerships to improve resource acquisition capabilities

• Internal reviews– Distribution

Introduced forensic team to perform detail analysis

Streamlined processes for underground conversions

– Transmission/Substation Reviewed remainder of system from lessons learned

Implemented plans accordingly 6

2005 Hurricane Season – Distribution and Transmission Equipment Repaired

• Distribution– 12,632 poles (FPL & non-FPL)– 930 miles of OH conductor– 570 miles of OH service conductor– 1.1 million OH splices– 30 miles of UG cable– 100 miles of UG service cable

• Transmission / Substation– 100 structures– 7 miles of conductor– 1 substation transformers– 7 regulators– 16 breakers

Lessons Learned from 2005

– Distribution Performance

– Distribution Standards

– Quality Processes

– Pole Maintenance

– Transmission Performance

– Substation Performance

– Weather Assessment

– Industry Benchmark

Retained independent outside consultant (KEMA) to examine the performance of FPL facilities during Wilma in an attempt to better understand whether transmission and distribution structures performed appropriately

Key Finding

FPL’s transmission, substation and distribution systems are designed to meet or exceed all required safety standards, and, during Wilma, performed as expected and in accordance with FPL standards

Most of FPL’s poles are designed 50% stronger than required by the NESC

9

Next Steps

• Evaluate recommendations from KEMA study

• Develop infrastructure hardening plan –”Hardening Roadmap”. Items under consideration:– Strengthen Poles

– Shorter Spans

– Conductor Size

– Undergrounding of Facilities

– Vegetation Management

– Other Design Considerations

– Substation Facilities
