Reliable and sufficiently detailed data is required to facilitate decision making in all activities and Distribution System Management. Controlling costs improve efficiency and reducing down time has become essential for a utility in order to be successful in the highly competitive environment of today where private utilities / distribution companies are coming into distribution. With the huge connected networks, number of spur lines and alternative feeds from sources the creation, updating and management of distribution data is a Herculean task the data of distribution systems is maintained through hand-drawn maps with facilities data printed in text form on them and available with the JE/linesman in charge of the feeder. These maps are rarely updated. The use of advanced information technology tools for maintaining a coherent database thus becomes very essential.
Geographic Information System is a system of mapping of complete electrical network including low voltage system and customer supply points with latitude and longitudes overload on satellite imaging and/or survey of Indian maps. Layers of information are contained in these map representations .the first layer corresponds to the distribution network coverage. The second layer corresponds to the land background containing roads landmarks, buildings, rivers, and railway crossings etc. The next layer could contain information of the equipment viz poles conductors transformers etc. Most of the electrical network /equipment have a geographical location and the full benefit of any network improvement can be had only if the work is carried out in the geographical context. Event while doing something as relatively simple as adding a new service connection, it is vital to know that users of the system are not affected by this addition. GIS in conjunction with system analysis tools helps to do just that.

[...] The efficacy of the GIS is largely dependent on the accuracy and the timely availability of the System data. The BRPL and BYPL face the biggest challenge in creation of a comprehensive geographic database of its Assets and the consumers. The rapid changes in the network because of implementation of schemes like HVDS, LT modernization and the system expansion make this task even more complex and laborious. So the GIS system has to be implemented in phases so as to meet the current and future needs of the utility. [...]
[...] Database Management and Update After data are collected and integrated, the GIS must provide facilities, which can store and maintain data. Effective data management has many definitions but should include all of the following aspects: data security, data integrity, data storage and retrieval, and data maintenance abilities. Geographic Analysis Data integration and conversion are only a part of the input phase of GIS. What is required next is the ability to interpret and to analyze the collected information quantitatively and qualitatively. [...]
[...] Visual communication is one of the most fascinating aspects of GIS technology and is available in a diverse range of output options Scale All maps, whether on a paper or inside GIS, are reduction in size of the earth. A primary purpose of any map, especially thematic map is to allow us to view important detail, for a large region at a single glance without the distractions of inconsequential or extraneous detail. The amount of reduction is primarily a function of the level of detail we need to examine our area. [...]
[...] Complexity of electricity distribution system is a good reason for introducing new information technology GIS (Geographic Information System) that together with an electrical network analysis package carries out complex power system analysis in acceptable amount of time. Load Forecasting Forecasting is the prediction of both the amounts and location of future electric load growth in a manner suitable for distribution planning considering customer load characteristics in a region for planning a new distribution network or extensions to the existing one.
