City, FPL Break Ground on New Underground Transmission Line

Published on October 19, 2021

The City of Miami and Florida Power & Light Company (FPL) broke ground today for a new underground power line that will help meet growing energy needs and improve service reliability for approximately 50,000 customers in downtown Miami and the surrounding area.

“Miami – and our downtown area in particular – continues to see incredible growth in terms of new residents, new businesses and new developments,” said Mayor Francis Suarez. “We welcome the timely investment by FPL in strengthening our power supply and doing so in such a way that the impact on our neighborhoods is as low as possible.”

The new underground transmission line will run underground along the Metrorail corridor from FPL’s Coconut Grove substation to a location near the Simpson substation in Brickell. FPL will also be building its new Dolphin Substation in the area to provide more customers with reliable power.

“We are excited to be working with the City of Miami on this new underground transmission line that will help us further strengthen and improve our system and serve our customers reliably for years to come,” said Manny Miranda, senior vice president of Power Delivery at FPL. “Part of our commitment to delivering America’s best energy value – clean, affordable, and reliable energy that our customers can count on in good and bad weather.”

The project’s unique location in an area with existing subway lines allows FPL to connect to existing facilities and provide the city of Miami with additional savings while providing reliable power to customers.

Construction of the underground transmission line is expected to be completed in December 2023. FPL is committed to working safely and respectfully in the community before, during, and after the project and will keep customers and the community informed throughout the construction if necessary. For more information on the project, customers can call 800-693-3267.
