GIS provides a useful way to visualize it as a set of map layers or themes, all over laid together to a common map base. In the last few decades, the electric power sector has been developing power substations, transmission, high voltage and low voltage lines to keep up with the rapid growth of the power demand. On the other hand, the suitable routes for new substations and transmission lines has been getting restricted, due to development of rural areas and the growing concern over environmental issues. One of the target of vision 2030 is to have 2000,000 new customers added to the power grid in addition to the existing 2,000,000 existing customers and also to reduce system losses, increase grid coverage and improve quality power supply .Power company consequently has to keep track of numerous poles, circuits, power lines, and transformers and customers and have ways of performing load study analysis and manage power outages. Information of location voltage and distribution of electricity of these facilities seem to be very overwhelming.

GIS effectively manages information on the distribution of electricity to customers and information describing the attributes of each customer such as
