Since 1987 the Tennessee Valley Authority (TVA) has had access to real-time data on cloud-to-ground lightning strikes in its service area through the Lightning Detection Network (LDN) operated by the State University of New York at Albany (SUNYA). Lightning data are displayed in real-time on personal computer workstations connected to SUNYA via satellite link and are recorded for later analysis. TVA is using these data to analyze transmission line outages (real-time and historical), provide warning of approaching lightning to line crews, develop ground flash density maps to replace isokeraunic maps previously used in designing transmission lines for lightning protection, and to learn more about lightning and its effect on TVA's transmission system. Lightning flashes that cause particular line outages have been identified and their current and multiplicity characteristics studied. This information may be used to allow more cost-effective transmission line design in the future.
