Ameren Corp. has completed an industry-leading 60 mile beyond visual line of sight (BVLOS) drone flight to inspect transmission lines. The company has worked with Black & Veatch and Collins Aerospace to complete drone flights. The flight demonstrated the maturing technology’s promise of more efficient monitoring of utility assets, especially in remote rural stretches. In 2017, a BVLOS drone was used to inspect nearly 10 miles of Ameren’s power lines near Newton, Illinois. The 2018 flight, featuring a special use vertical take-off and landing drone, went six times the distance of last year’s flight.
