Utilities face mounting pressure to inspect ageing infrastructure, mitigate wildfire risks, and reduce costly outages—especially in remote or hard-to-reach locations. Traditional methods like helicopter surveys or ground crews are slow, expensive, and increasingly insufficient in the face of worsening climate conditions and rising demands for reliability.
Nomadic Drones, a startup originally formed at GUC Berkeley and now based in Munich, has developed a unique solution: self-charging, autonomous drones that live directly on high-voltage power lines. Using the lines’ electromagnetic field, the drones perch and recharge without returning to base. This innovation enables near-constant surveillance of grid infrastructure with minimal human intervention.
These lightweight aerial units, weighing around 4.4 pounds, are equipped with high-resolution cameras and sensors. While stationary, they monitor conditions such as cable temperature and line sag. Once fully charged—typically within two hours—they resume their patrol duties. The drones are designed to operate independently, significantly reducing the need for on-site personnel.
Driven by the destructive California wildfires in 2018, the founders envisioned using aerial systems to spot potential failures before they spark disasters. Initial interest from utility companies encouraged further development. In Europe, Nomadic Drones partnered with firms like Westnetz to test and refine the concept under real-world conditions. The current focus is on improving material durability for long-term deployment in outdoor environments.
To process the massive data these drones collect, the company is also developing software that uses AI and machine learning to analyse images and sensor outputs. This platform flags issues such as mechanical wear, heat anomalies, or structural weaknesses—accelerating response times and freeing human inspectors from hours of data review.
In the U.S., regulatory challenges around drone operations—particularly autonomous, beyond-visual-line-of-sight flights—remain. However, utility corridors often lie in restricted or isolated airspace, which may allow some exemptions. Nomadic Drones is currently preparing pilot projects with contractors supporting Pacific Gas & Electric (PG&E), aiming for eventual large-scale adoption.
The long-term vision is a fleet of permanently deployed drones living on the grid, not just inspecting it. With a fleet of 100 to 1,000 drones, a utility like PG&E could maintain real-time oversight across vast infrastructure networks. Despite their close proximity to critical assets, the drones present minimal risk to equipment, offering a low-impact, high-benefit solution to one of the grid’s most pressing challenges: visibility.
