American Transmission Co. Improves Response Time, Accuracy with Esri Technology

Redlands, California—As the owner and operator of the high-voltage electric transmission grid serving a four-state area, American Transmission Co. (ATC) needs to quickly dispatch field crews to the exact locations of power-flow disruptions to minimize outage times and help keep the lights on for homes and businesses. The company accomplishes this by viewing utility data, Bing Maps, and weather in one interactive, company-wide map, using server-based geographic information system (GIS) technology from Esri.

"The simple-to-use, GIS-based Web application helps system operators quickly deploy restoration or maintenance crews to the exact fault location, resulting in shorter response time and, ultimately, minimizing unplanned restoration outages," says Eric Fowler, asset applications development lead with ATC. "With GIS technology, ATC operators are able to manage the system with real-time information and link directly to our asset information."
