March 1, 2007 Report
An Overview
October 30, 2006 – Staff Workshop
2
Presentation Topics
Goals Increase efficiency while increasing the scope of subject
matter being reviewed Promote self-critical reviews
Old v New March Reporting Step through Vegetation Management as an
example Normalizing reliability indices
“Actual” – adjustments = “Adjusted” Report appendices: all the various metrics
3
What is our goal?
Storm Hardening efforts first discussed at the November 29, 2005 Internal Affairs
Storm Hardening Goals – are general public interest goals Minimize damage due to major
weather related events Minimize restoration times
following major weather events Minimize the number and
magnitude of rate increases Reliability activities affect non-
storm days and storm days. Efficient use of resources Promote utility self-critical
review through reporting
4
Old Report Process(Storm Hardening, Pole Inspections & Other Reliability
Indices)
File summary data – without utility self-critical discussion or analysis Staff requests selected detailed data Trends in detailed data discussed/disputed with
utility Interpretations of trends in data
discussed/disputed with utility Management Audits Drill-down audits of data records supporting
summary reports.

2006 Reliability Performance(Rule 25-6.0455 F.A.C)
Discuss overall performance absent adjustments (Form 102) Describe the level of detailed reliability data the Company tracks Describe Company efforts to increase critical review of detailed
reliability data Describe the process used by your company to identify and
select the level of detailed reliability data Discuss adjustments

15
Generation Events - Adjustments (Rule 25-6.0455 F.A.C continued) Discuss EACH generation event that resulted in customer
outages Address whether the event was localized or system-wide Describe the Company’s efforts to avoid or minimize any similar
events in the future in terms of the level of costs incurred and outage duration
(Appendix) Provide the 2006 service reliability data for each generation outage event that is excluded from your Company’s 2006 Annual Distribution Reliability Report pursuant to Rule 25-6.0455 A table Electronic file Date, C, CMI, CI, Total Repair Cost, Replacement KW & KWH
