NASHVILLE, Tenn. – Nashville Electric Service crews will blast cannons three times per night in an attempt to scare off pigeons roosting at a downtown substation.
NES officials said the sound cannons will be used at the Central Substation once per hour between 7 and 9 p.m. for the next several weeks.
"There will be a loud noise that will go off. Basically it disrupts their roosting pattern so they don't want to come back and roost at our equipment," said NES spokesperson Laurie Parker.
The cannons produce a loud noise similar to firecrackers and disrupt the nesting pattern of the birds roosting at the substation.
"We've had crews that have been noticing more and pigeons that are starting to roost at that substation, and that creates problems, said Parker.
If the birds get into the substation, they could possibly cause a power outage.
"Because they're roosting there and over time it builds up, and it can corrode the switches and it can actually cause the equipment to fail, resulting in an outage," Parker explained.
"We have not experienced any recent power outages, but the potential is there because of the increased number of birds in the substation,” Jack Baxter, NES Operations Manager, said in a statement. “The cannon should scare the pigeons and make them find someplace safer to roost.”
The Central Substation provides electricity to one-third of the downtown area.
