Indian power distribution company pins hope on GIS mapping

India, 13 May 2007: Having faced complaints of frequent power cuts and inflated billing from dissatisfied consumers and reprimands by the Delhi Government for taking inadequate steps to improve the power situation in its area, power distribution company BSES is now hoping to improve its services by opting for GIS mapping.

The discom is hopeful that the Rs.25-rore project, which has been implemented in some parts of its distribution area, will “bring about a quantum leap in operationally efficiencies”. Sources said GIS mapping would help the discom reduce Aggregate and Technical Commercial losses (AT&C), reduce the time for installing new connections, and pin down the problems on a real time basis. “It will help increase efficiency, check power thefts and help in load shedding forecasting,” sources said.

The monitoring tool will allow the discom to provide a common facility through which the entire organisation can access facilities and information necessary to manage, operate, maintain and plan the expansion of its electrical distribution system.

“Through GIS mapping the discom will get an accurate geographical representation of assets spread over its distribution area. All the grids and sub-stations have been covered and marked on the GIS map along with the details of assets installed including transformers and circuit breakers,” discom sources said, adding, “the entire network including grid stations, cables, transformers, poles and street lights are being mapped”.

A BSES official said at present GIS mapping in the Capital is limited to R. K. Puram, Nizamuddin and Mayur Vihar Phase-I and II. He said the system, which would be extended to the entire area of distribution by March 2008, is fully compatible with the SCADA system and along with Distribution Management System (DMS) is expected to improve the technical losses by at least 1 to 2 per cent. The technology’s potential to curb power theft was also pointed out. “With proper energy auditing and proper survey of consumers, an additional improvement in the commercial losses resulting from theft is also expected,” sources said.

GIS mapping, which is already in use in some parts of North Delhi Power Limited distribution area, also helps in quick identification of fault locations, thereby reducing response time.
