T&D World Podcast: Cleared for Takeoff: Navigating UAS Regulations in the Power Sector
Listen Now!
In this episode of the T&D World Live podcast producer Christina Marsh sits down with Nate Ernst, president of the Tactian Group, to explore how unmanned aircraft systems (UAS) are reshaping electric utility operations.
Ernst talks about how utilities have traditionally relied on helicopters for tasks such as power line inspections and vegetation management in difficult terrain. Around 2010, innovators began adapting commercial drones to handle many of these same functions, offering a safer and sometimes more efficient alternative. What began as simple visual inspections has expanded to include thermal imaging, LiDAR mapping, and digital twin modeling for entire transmission corridors.
Regulatory Milestones
Early drone operations required the FAA’s 333 exemption, a stopgap that allowed commercial flights on a case-by-case basis. The introduction of Part 107 regulations in 2016 standardized training and certification for small drones under 55 lbs, opening the door for utilities to launch internal UAS programs. Many utilities now operate their own fleets, using drones for routine inspections and data collection.
Part 108
Looking ahead, the FAA’s proposed Part 108 rule, which would allow beyond-visual-line-of-sight (BVLOS) operations and the use of heavier drones — up to roughly 1,300 lbs — under a “corporate-centric” operational model. This shift would enable drones to cover longer distances and carry out more complex tasks, but it will also require more robust safety management systems and multi-person flight operations. Public comments on the proposal are under review, with final rules possibly arriving within a few years.
Opportunities and Advice for Utilities
Ernst believes UAS will not replace helicopters and bucket operations entirely but will increasingly complement them, reducing risk and enhancing data quality. He urges utility leaders to evaluate the business case carefully, learn from early adopters, and attend industry conferences to gather real-world insights. With BVLOS operations on the horizon, he sees now as the time for utilities to plan scalable drone strategies that can improve safety, lower costs, and expand capabilities.
