The Tennessee Valley Authority (TVA) is successfully operating the Tecnam P2012 Sentinel special mission platform (SMP) to protect and maintain its vast electricity grid. Equipped with cutting-edge Light Detection and Ranging (LiDAR) and high-resolution multispectral cameras, the P2012 SMP is transforming how TVA evaluates threats to transmission lines across its network.

The primary threat to the region's power system, the backbone that allows local utility companies to provide electricity, comes from large trees and vegetation. To mitigate these risks, especially ahead of severe weather seasons, TVA utilises the P2012 SMP to conduct an annual survey of its infrastructure. The advanced onboard systems create precise 3-D models of the earth's surface and comprehensive topographical maps.

The aerial programme, fully implemented in 2025 following five years of research, has yielded staggering efficiency gains. While traditional ground crews can survey up to five miles of transmission corridors a day, a two-pilot crew in the P2012 SMP surveys approximately 450 miles a day, a 90-fold increase in productivity.

Flying at 120 mph, the P2012 SMP captures data at an astonishing rate of three and a half acres per second. The system's resolution is so powerful that it can zoom in on a single leaf, giving TVA unparalleled situational awareness to identify vegetation growing into the right-of-way before it causes an outage. Out of the TVA's 16,500 miles of transmission lines, more than 5,000 miles are part of this critical vegetation management cycle.

Francesco Sferra, Tecnam P2012 special mission platforms sales and business development manager, comments on the success of the programme: “The P2012 SMP was engineered exactly for this kind of demanding, high-endurance aerial work. Seeing the TVA utilise the aircraft's exceptional payload capacity, stability and twin-engine reliability to seamlessly integrate complex LiDAR and camera systems is a true testament to the platform's versatility. We are incredibly proud that Tecnam aircraft are playing a vital role in keeping the lights on for 10 million people while significantly enhancing the safety and efficiency of TVA's operations.”

The programme not only protects critical infrastructure like hospitals, schools and nursing homes from outages, but it also significantly reduces maintenance costs, allowing TVA to reinvest in infrastructure for fast-growing regions.

“We're able to inspect much faster, much safer with a great level of detail,” adds Will Sanders, TVA right of way programme manager. “We really support our people so that they're able to get out there and make decisions on what is a real threat.”
