GIS Usage

North Delhi Power Limited (NDPL) distributes power to North and North West Delhi. For any

utility company, effectively managing network distribution requires good network maps. With

the help of quality maps, one can plan and utilize resources better. That’s exactly what NDPL

has done.

NDPL has used GIS (Geographic Information System) to capture ground maps. After

implementing GIS, it became a communications platform for various operations of NDPL.

1. Asset Information : GIS has enabled NDPL’s employees to know the details of

each district, zone, grid station, and even of each consumer, at the click of a button.

E.g.: For instance, if a consumer faces a power cut problem and brings it to the notice of

the NDPL authorities, they can trace it out sitting their desk. They can ascertain the power

grid from which the consumer is connected and can also determine the exact transformer

from where he/she gets power. This helps in resolving problems faster than ever before.

2. Disco Network Planning: Similarly, if a customer wants to increase the power load

for their residence, GIS helps NDPL employee to determine whether it can be done

from the same transformer or whether they need to get another line from a different

transformer.

3. Control on Restoration : Another interesting feature enables NDPL to determine

the shortest route to plant a new electrification network.

Eg : For instance, if NDPL wants to expand their existing electricity network, they can

determine the shortest route between two end points through the system, without actually

going out to the field, which was the case earlier. This has improved the efficiency of NDPL

and has also helped them to cater to the needs of the consumers faster.

These benefits helped NDPL to save a huge amount of money, a whopping 1.26 crore in the

very first year of GIS implementation.

4. Customer Information Index: GIS also provides a detailed list of all NDPL

consumers. Hence, if there is a scheduled power cut at a specific location, they can

get the data about affected consumers within that specified location and inform them

in advance. All NDPL users have access to it and it can serve 200 concurrent users.

They have used software called GE Small World and the data is stored in the GE

small world application server.

5. Interfacing to others : GIS also acts as an input to other enterprise software such

as SAP and SCADA. But the extensive use of information makes it a unique project

in itself. For people going to the field to lay a network or to check faults in any of the

transformers, the system provides invaluable help.

Eg: They can download the GIS map of the area to a PDA and carry it with them, hence

making their life much simpler and work much faster.

6. Trouble Call Management System : As complete customer information is available

in SCADA via GIS, hence in case of any power failure, the same can be forwarded to

Call Centre for information

One of the key challenges for them was data creation. With no prior knowledge and lack of

availability of a good consultant or agency, it was a challenge to gather such extensive data.

The key benefits of this project were faster service to consumers and faster and more cost-

effective new network layouts.

Senior management can also monitor the development sitting right at their desks. All this

has reduced costs to a great extent, which indirectly benefits consumers too.

In the next phase, NDPL plans to integrate the GPS system in their recovery van so that they

can monitor it on the GIS map itself. This will help them provide faster and planned solutions

to power failure problems.

They also plan to integrate other applications such as remote meter reading into a single

application, which will help them get more productive results
