Motives for GIS base creation are depicted as basis for network operation improvement and loss reduction. Improvements of software for network planning and analysis that include GIS elements are described, specially those related to future loss reduction application. Conception of loss reduction based of collected GIS and energy data in Serbian distribution networks is presented. Presentation is gradual: from the most detailed data set to the least detailed but necessary data set collected in distribution utilities.
Keywords: Low voltage network, loss reduction, GIS, BIS.
