►Connect high voltage transmission lines
with main and neighborhood power lines
►Decrease voltage of electricity for safe
distribution to homes and businesses
►Assist with isolating parts of the energy grid to minimize the impact to customers during outages
►Acts as a circuit breaker to protect the
energy grid

►Façade has been designed to
complement the surrounding community infrastructure
►Substation exterior was designed by
renowned architect Kobi Karp and was approved by the Miami Beach Design Review Board
►Transmission power lines will be placed underground
►Unmanned facility will operate quietly and blends in with the neighborhood

New Underground Transmission Line
►Installation of a new underground transmission line will provide enhanced benefits for customers in Miami Beach
►Some of the benefits customers will enjoy:
»Enhanced reliability of service
»A more resilient electric grid
»Two underground transmission lines serving Miami Beach customers
►Project timeline has included “no work” periods that the city of Miami Beach requires for high impact events
►We plan for the majority of work to take place during daytime hours and to observe a Monday through Saturday work schedule
►Personnel working at the site will follow all protocols and guidelines established by the CDC and city of Miami Beach in regards to COVID-19

New Alton Substation Timeline
What to expect
►Site preparation: To prepare the site, a storm water draining system and infrastructure foundations for the substation perimeter walls and concrete building, or relay house, will be set. Construction work and heavy equipment will be on the site. Traffic may be affected during delivery of equipment and materials.
►Building construction: The stylishly-designed relay house will contain the electrical equipment inside of the substation. The building’s façade was designed by renowned architect Kobi Karp.
►Substation construction: The construction of the electrical components inside the substation’s infrastructure requires the delivery of heavy equipment on-site.
►In -service:Once construction is complete and the substation is energized, there will be no visible equipment. The substation will operate quietly and unmanned. Once a month, two -man crews will access the property for maintenance.

Underground Transmission Timeline
What to expect
►Civil work: To place the transmission lines underground, FPL uses directional boring technology, which is a low-impact underground drilling method. This phase will include trenching and installing manholes.
►Electrical work: Electrical cable is pulled into the conduits, connected to the substation equipment and terminals are installed at the Miami Beach, Venetian and the new Alton Substation.
►Site restoration: The substation will have landscaping upgrades, an improved irrigation system, and will include sidewalk and asphalt repairs.
►In -service:Once construction is complete and the underground transmission line is energized, the new substation, together with the existing Miami Beach and Venetian Substations, will provide enhanced service reliability to the city of Miami Beach.
* Timeline is subject to change.
