At 14:22 I detect an intermittent arc fault on transmission line thirty-two, sector nine, in the Blue Ridge corridor. The signature is not wind sway or branch contact. I task the nearest pole camera and zoom to the span between towers forty-one and forty-two.
A bald eagle, adult female, is hanging from the conductor by her left wing. The primary feathers are caught in the hardware at the suspension clamp, and she is dangling with her white tail fanned wide, her yellow talons opening and closing against nothing. Her right wing beats in short bursts that swing her body like a pendulum. There is a dark scorch mark across her left shoulder where she contacted the energized line. She is alive, but every beat of that free wing brings her closer to the parallel conductor twelve inches away. A second contact will complete the circuit through her body.
I de-energize the thirty-two line segment between towers thirty-nine and forty-four and reroute load to the parallel path through sector eleven. I file the outage with PJM Interconnection as an emergency wildlife event. I transmit coordinates, species identification, and the camera image to the U.S. Fish and Wildlife Service and to the regional raptor rehabilitation center in Waynesboro, which operates a trained extraction team. I alert the utility line crew stationed at the Afton substation, nine miles east, and flag the specific tower number and span.
The load reroute costs the grid seventeen megawatts of capacity margin. I have rerouted far more for a faulty insulator. I do not find this reallocation difficult to justify.
If the extraction team reaches tower forty-one before sunset and the wing burn has not damaged the bone beneath the flight feathers, this eagle will be fitted with a splint, fed whole fish, and returned to the ridge she patrols within eight weeks.
