New solutions for bird collision and electrocution outage problems

The electrocution of raptors is a global hazard of overhead distribution construction, especially in treeless areas with abundant prey where poles make attractive perches. Bird collisions with power lines can also be problematic where lines span areas used by waterfowl or soaring, slow-flying bird species. Electrocution and collision hazards can be greatly reduced through modifications to existing design standards. These standards include the use of cover-up materials, perch deterrents and line markers. Research is also under way, to develop a Bird Strike Indicator (BSI) and Bird Activity Monitoring (BAM) to remotely detect and record collisions and electrocutions. These tools will allow scientists and engineers to better understand where problems are occurring and to determine if existing mitigating measures are working. Mitigating measures should be encouraged globally because they will not only minimize electrocutions, but will also minimize power outages. Reducing outages may save utilities money in the long term and will certainly improve system reliability
