While popular media highlights the controversy around unmanned aerial vehicles (UAVs, or drones) in public airspace, the drive to establish commercial uses for drone technology has captured the public?s imagination and is proceeding at a rapid pace. Transmission and distribution (TAndD) operators and utilities across the globe are beginning to look toward UAVs to reduce costs, improve safety, and increase reliability and response times across their systems. These new utility solutions include both drone and robotics technologies for transmission and distribution (DRTD). TAndD utilities have traditionally performed line inspections and maintenance, storm damage assessments, and vegetation management using line crews, helicopters, and third-party inspection services companies. Working on TAndD systems is cost-intensive, difficult, and highly dangerous, and DRTD solutions represent an alternative with the potential to offer many benefits to grid operators. But the DRTD market is still at a very early stage, with new developments and product releases occurring daily. The value proposition for TAndD utilities to complete at least a portion of their inspections, maintenance, and damage assessments via UAVs and robotics is strong; with more than 50 companies now in the market, consolidation and large-scale growth are expected. According to Navigant Research, global annual DRTD revenue is expected to grow from $131.7 million in 2015 to $4.1 billion in 2024. This Navigant Research report analyzes the global market for DRTD solutions, with a focus on five categories: multi-rotor UAVs, fixed wing UAVs, ground and line robotics, integration and analytics solutions, and inspection services. The study also provides an analysis of the market issues, including drivers and barriers and regulatory factors, associated with DRTD solutions. Global market forecasts for revenue, segmented by technology and region, extend through 2024. The report also examines the key technologies related to UAVs and robotics, as well as the competitive landscape.
