2004 - 2005 Record Breaking Storm Seasons
• 2004 was unprecedented
– 3 back-to-back storms
within 36 days
– Nearly 47,000 workers from
39 states and Canada
• 2005 is most active and
destructive season on record
– 4 hurricanes affected customers
– Nearly 45,500 workers from
36 states and Canada
• Wilma alone had the largest
impact to our infrastructure
– Largest workforce ever
assembled
– Quickest deployment to the
field after a major hurricane
– Significant impact on electrical
infrastructure

2005 Storm Season Review - Lessons Learned
• Infrastructure “hardening” is needed in the design,
construction and operation of electric systems
– Evidence of more active multi-decade hurricane cycle
– Growing customer base within territory
– Customer expectations higher
• Storm Secure Plan developed to strengthen
electrical grid for future hurricanes
