To maintain their assets and provide better customer service, more public- and investor-owned electric utilities are integrating their core business systems with GIS. A centralized system with a consistent, accurate landbase gives utilities the power to manage geographically distributed facilities and to streamline a broad range of company workflow processes from outage and work management to engineering analysis, document management, and customer billing. If the system is hosted over the web, all authorized users—executives, operators, field staff--can quickly access one source for standardized data, maps, and applications, with only a browser and Internet connection. The considerable work efficiencies realized in-house translate to faster outage response and reduced outage durations in the field, lowered restoration costs, and improved public relations and customer satisfaction.
