Vulnerability Concerns
• Coastal Flooding - Raised pad mounted
equipment
• Insufficient Outside Crews - Enter storm
restoration contract
• Heavy Right-of Way – Increased clearances
on distribution lines in rural wooded areas
• Multiple Storms – Conversion allows for
back feed of any substation (80 %
completed - 4 yr. completion)

conditions caused by the disaster.
– Limit damage to Cooperative property.
– Provide for the orderly restoration and repair of
the Cooperative’s transmission and distribution
system.
