Florida Keys Electric uses helicopter to inspect transmission lines, about two weeks

Florida Keys Electric Cooperative launched its annual helicopter-based aerial inspection of high-voltage transmission corridors along U.S. 1 in the Middle and Upper Keys the week of March 2, 2026. The cooperative says the aerial survey will operate roughly 7:30 a.m. to 5 p.m., Monday through Saturday, with the helicopter’s daily location between Marathon and the Ocean Reef Club determined by wind and traffic conditions.

FKEC described the project as large in scale: more than 1,600 transmission poles to survey, including about 11 miles over water and many land-based poles in hard-to-reach places. FKEC is using a helicopter contractor to execute the visual inspection and said the work complements routine drone surveys, with FKEC officials noting, “While FKEC does use drone technology to survey power equipment, highly trained line workers on the helicopter remain the most effective way to complete a project of this scale.”

There is variation in published timelines for the work. FKEC’s current advisory states, “The work is estimated to take until May 19 to complete depending on weather conditions.” A local weekly described the inspection as starting the week of March 2 and estimated the active flying in local zones could last about two weeks, weather-dependent. FKEC and the local outlets emphasize the project is weather-sensitive; FKEC’s May 19 date reflects the broader official window while the shorter two-week figure appears to refer to more limited, area-by-area helicopter activity.

Business owners and residents along U.S. 1 have been given a specific safety advisory: “Business owners and residents along U.S. 1 from the Monroe County line to Marathon are asked to secure any loose, unattached items such as furniture, plants or other goods displayed near or below the main transmission lines.” FKEC also issued a motorist caution, saying, “FKEC reminds motorists to drive safely while this inspection is in progress and to keep their focus on the road and not the helicopter overhead.” The cooperative reinforced that crews will adjust daily flight paths for wind and traffic considerations.

FKEC frames the inspection as preventive maintenance intended to protect service reliability, writing, “The aerial inspection increases the reliability of our local electric service and ultimately prevents power outages through regular system maintenance.” Members with questions can call FKEC Member Service at 305-852-2431. The cooperative’s Tavernier office is listed at 91630 Overseas Highway, Tavernier, FL 33070. Residents along the corridor should secure loose items and expect intermittent helicopter flights during daytime hours through the spring, weather permitting.
