2004 – 2005 Hurricane Season What We Did Post Storm
Decentralize the restoration process Decision making ability is at the substation level Distribution assessments and restoration begin as soon as it is
safe to report to work
Draw upon Southern Company affiliates for assistance as needed
Perform “sweeps” – slide 29

2004 – 2005 Hurricane SeasonWhat Is In The Future Underground Help with vegetative management in right of way Evolving specifications Increased data from our mapping system Distribution Assessment Teams

2004 – 2005 Hurricane SeasonWhat Is In The Future Vegetation Management Pole Inspections
maximize plant facility life gather information necessary to manage and prioritize
needs and resources minimize unscheduled or emergency maintenance by
performance of preventative maintenance NESC and Specifications
10
Vegetation Management Work performed by contractors Clearance at the time of pruning based on NESC
requirements Program performance indicators
Vegetation SAIDI Customer satisfaction - justified PSC complaints on tree
trimming Public Safety – number of documented accidents related
to vegetation
11
Vegetation Management (cont.) Program utilizes a mix of maintenance pruning on
entire circuits, targeted spot pruning on portions of circuits, and spot pruning in response to customer call ins.
Annual work plans developed from Forestry Services field inspection data, outage data, customer call ins, and field engineering reports
100% of transmission field inspected each year – all hazardous situations corrected (i.e., leaning or dead trees)
12
Distribution Line Inspections 249,802 wooden poles as of December 2005. 10 year inspection cycle for all distribution poles Gulf started its 2nd inspection cycle in 2003. All poles are inspected using one of the following
inspection types: Visual Sound and Bore Partial Excavation Full Excavation
13
Transmission Line Inspections 12 year inspection cycle for all transmission poles
and structures Aerial patrol of system at least 4 times per year All structures are inspected every 6 years using one
of the following inspection types: Ground Inspection Wood Ground Line Treatment Inspection Steel Ground Line Treatment Inspection Comprehensive Walking Inspection Comprehensive Aerial Inspection Routine Aerial Patrol
