American Electric Power: drone imagery finds a second failing static line at a substation
After a static line fell onto a 345 kV bus at an AEP substation, crews imaged the scene by drone from outside the yard. The imagery revealed a second static line close to failure that manual inspection had missed. The manufacturer credits this with avoiding nearly $8 million in losses, without showing how that was calculated.

Before
Manual inspection close to the hazardous substation, which could not reveal the condition of the second static line.
With drones
After a static line fell across a 345 kV bus, the crew flew a drone from outside the substation and analysed the imagery in the cloud.
Outcomes
| Metric | Value | Basis |
|---|---|---|
| defects found | a second static line on the brink of failure, not visible from manual inspection | Reported |
| cost avoided | nearly US$8 million (repairs, outage costs, labour) | Reported |
| time | hours saved and shorter customer outage (not quantified) | Reported |
Caveats & limits
- Manufacturer customer story (Skydio); the $8 million figure has no breakdown or method.
- Year, site and drone model are not stated.
- Docked, programmatic inspection is described as a future plan, not a result.
