• Primary drivers of higher costs:
— Much more expensive equipment and materials

Ho w is the additional cost co vered ?
• Build to overhead standard — most cost
effective
• Cost for overhead service is reflected in our
cu rrent rates
• Cost difference for underground service paid by
those who benefit

— Applicant provides written request to FPL
— FPL provides non-binding ballpark estimate
— Applicant secures easements and pays engineering
deposit
— FPL performs detailed engineering and determines cost
— Engineering deposit applied to total cost if project

Conversion Process
• Conversions from overhead to underground are
challenging
— Require private easements for above ground
equipment
— Rearranging customer service entrances require an
electrician
• May trigger additional improvements to meet
updated code requirements
— Involve other facilities (telecommunications and
cable)
— Trenching will require customers to restore
landscaping, sidewalks, driveways
— Disruption to ingress / egress _
• Limited experience with large sca vers�ons
