FPL proposes 500 kV Andytown–Oasis transmission corridor; preliminary route touches Southwest Ranches

Summary
Florida Power & Light outlined a proposed 500 kV transmission extension from the Andytown substation toward a planned Oasis substation in south Miami‑Dade, saying a preliminary corridor crosses roughly 1,000 feet of Southwest Ranches and that certification filings will proceed under the state's transmission line siting process.
Florida Power & Light presented details of a proposed transmission expansion it calls the Andytown–Oasis project, telling the Town of Southwest Ranches council the plan would extend a new 500 kilovolt transmission line from the existing Andytown substation south into Miami‑Dade County to a planned Oasis substation.
"We chose what we refer to as a preliminary preferred corridor," FPL External Affairs Initiatives Director Baldwin English said, showing maps of a study area and a corridor FPL identified after weighing environmental features, existing linear facilities, schools and land ownership. English said the magenta conceptual center line is illustrative and that the yellow preliminary corridor is where the line could ultimately be sited. "About 1,000 feet of it actually touches on Southwest Ranches," he said.
Project manager Craig Coughlin explained the company has filed a need determination with the Public Service Commission and plans to submit an application under the state's transmission line siting process later this month. He said design and permitting are expected to take about three years (2026–2028) with construction starting in 2029 and lasting a couple of years.
Council members asked technical questions about the corridor alignment and whether the new line would be east or west of existing wires; FPL staff clarified the magenta line was conceptual and the corridor could move within the yellow study area. English said the blue area on the presentation maps represents predominantly FPL‑owned property and that the route would also pass near the Quarry and Levy substations.
FPL described the project purpose as meeting projected load growth arising out of Miami‑Dade County and said it will seek state certification. The company committed to follow up with the town on specifics about local undergrounding and other ongoing local projects when officials requested a schedule update.
The presentation did not include a final route, specific parcel easements, or a formal local permitting decision; those elements will be developed during design and the state certification process. FPL said it would provide additional details to the town’s undergrounding team and respond to follow‑up questions about timelines for nearby undergrounding projects.
What happens next: FPL will file for siting certification; town staff said they will continue to seek updates from FPL about local impacts and the undergrounding schedule for residents.
