GIS for Distribution Loss ReductionEstimates of Implementing GIS at DelhiInitiatives taken by GIS group established at Central Technical Services of the company are as follows -

Development of Functional Requirements and Data Model. Updating of Reliance Corporate Land base Maps. Capturing the entire EHV/HV network. Capturing the entire LV network. Capturing Consumer Information. In House Digitization and field QC. Consultancy Services by REL

GIS for Distribution Loss ReductionUpdating of Reliance Corporate LAND base Maps Integrated large scale corporate land base map prepared based on RICs data requirements with base data as IKONOS imagery imported from Space Imaging. IKONOS imagery digitized by RDWL team through network of digitization vendors. Maps supplemented with field survey information conducted by contractors identified by RDWL.

Flaw in above system Information updated by RDWL was insufficient for locating Electrical network and individual Consumer Service points.

Solution * Updating of all buildings with service line feeding * Including all new transport features including road, railway, flyovers.

GIS for Distribution Loss ReductionCapturing Consumer InformationNon-availability of accurate consumer records had been one of the main reasons for commercial losses.

GIS based consumer indexing has been carried out by many DISCOMS / SEBs, without much of a fruitful result.

At BSES, Delhi it is at a conceptual; stage and different models are being evaluated for collecting consumer information

The consumer data being collected will be integrated with its building id for its spatial location and network connectivity with its feeding structure id in GIS. Cost Estimates for Consumer Data Collection

GIS for Distribution Loss ReductionEstimated Benefits of GIS As per estimation, GIS will benefit by decreasing both Commercial and Technical losses. Based on assumption for 0.5%, 1.5% and 2.5% increase in MU billed for the first, second and third year respectively by reduction of losses and better O & M.

Benefits after GIS Implementation Note: From the table, increase in revenues with prevailing tariff is 175mn, 265Mn and 450Mn respectively for three years.

1Attending NO SUPPLY complaints.Consumer NO SUPPLY complaints are received and recorded at the Receiving Stations ( called as COMPLAINT CENTRES).

The complaint is then passed over to the district for rectification. A district is manned by one / two linesman gangs on 8 hrs. shifts throughout the day and are provided with cycles / motorcycles for mobility.

On rectification of a complaint, an acknowledgement in the form of a signature of the consumer is taken as a token of satisfactory attendance of the complaint

In case of fault, the linesman isolates the fault, restores supply as far as possible and informs the details to the Controlling Station to make appropriate arrangements to attend the fault.

If the meter of the consumer is found faulty, a request for providing direct supply to single-phase residential and water-supply meters is available in the form of a request letter which is pre-printed on the reverse of the complaint form. In other cases,

The linesman reports back to the Complaint Centre the details of the complaint and the rectification work done.
