Main tracks 9

Loss reduction achieved through 9

Roll out of networks

9

Enhancement of billing net.

9

Adopting the right metering system

9

Installing electronic meters.

9

Focused drive on collection.

9

Containing theft by enforcement raids on consumers identified thru’ 9 Transformer loss analysis drilled down to cluster Analysis & Other sources 9 Data analysis

Data Analytics: Smart Way To Identify Theft

4

Data analytics - Process 9

This initiative was undertaken at Delhi, with the strategic intent of providing inputs on potential

cases of theft to the Enforcement teams 9

Since its inception, the team has provided a large number of successful leads to BSES Delhi.

9

This initiative has been identified as one of the key drivers for AT&C loss reduction .

9

Comprehensive approach is the right method

9

-

Consumption analysis

-

meter download analysis

-

Survey data

Key Drivers -

Tamper Analysis

Consumption Analysis

Billing Database Analysis

Tamper Analysis

6

Tamper analysis

9

Tampers result in under recording of energy

9

Various circuits inside the meter or wiring at the terminal box is manipulated

9

-

Current circuit

-

voltage circuit or

-

Switching off power supply (SMPS)

Tampers logged by meter along with load profile is analyzed to identify theft

7

Types Of Tamper 9

Voltage Circuit tamper (Low & Off) -

9

Power supply switched off -

-

To check if there are periods of Power supply failure logged by meter beyond supply failure

Current circuit tamper (Shunting) -

9

This is easily detectable

This is the trickiest one to detect due to issue of false alarms

Load imbalance -

Certain current circuit tampers are not detected at times.

-

Load imbalance comes handy at these times

8

Remote Operated Relays

9

A very common methodology in Delhi

9

This may not be detected when we check consumption using Accucheck

9

Remote circuits are used in following ways:

9

-

For opening or bypassing current circuit

-

For altering voltage circuit

-

For switching on and off power supply

Can be detected from study of tamper events / load profile and instantaneous parameters

9

10

Electrostatic discharge (ESD)

9

This is a novel method used to manipulate the electronic meters.

9

When subjected to ESD , meter would get into sleep mode till the time it is waken up by a power supply interruption.

9

This method would leave few symptoms in the data stored in the meter through which one can detect such cases.

11

Consumption Analysis

12

Consumption Analysis: Key Focus

9

Surveyed 1.0 lac consumers contributing to 60 % of company’s revenue -

Nature of Activity

-

Collected information to calculate their consumption

9

Establishing benchmarks for different commercial / industry segments.

9

Examples: -

Commercial Categories –

Fast Food joint: 10 units per month per Sq Ft

–

Shopping Malls: 3.5 to 4.5 units per month per Sq Ft

13

Case Study: CNG Pumps 9

Complete list of CNG outlets was taken up for Analysis from Secondary Source 9

Many CNG outlets in Delhi consume 10,000 units (monthly). While CNG outlets in Mumbai typically consume upwards of 50,000 units

9

Reason for difference Delhi CNG outlets use gas turbine for powering compressors.

9

We decided to continue our drive for those CNG pumps that had not shifted to Gas Turbines. 9

This led us to infer that “lot of CNG outlets were involved in theft”

14

Case Study: Hotels 9

Hotels nailed based on Consumption Analysis 9

Found some budget hotels consuming 200 units per A/C room per month. ~~ Almost 50% of normal.

9

Checked – Key parameters –

Room Tariff rate

–

Occupancy

–

Effectiveness of cooling in each case

Raid conducted - Booked 20 economy hotels for thefts.

15

Billing Database Analysis

16

Database Query Logic - Examples

9

9

Units Consumed (Monthly) / Maximum Demand Recorded -

Units Consumed (Monthly) / Sanctioned Load is another parameter on which we can analyze

-

Often this is due to premise not being used

Residential load greater than -

15 KWatts in low income locations or > 30 KWatts at any location

-

Above will be suspect for tariff misuse

9

Faulty / Burnt meters that have been replaced

9

Drop in consumption

9

Reading being developed for more than certain duration -

Consider cases > 4 months

-

Check for sanctioned load vis a vis units being billed

New trends

9

Due to effective monitoring the following are in the raise. 9

Burnt meters : ƒ 22 % of meters removed from site are burnt meters.

9

Theft of meters : ƒ The stolen meter complaints is showing an increasing trend

Conclusion 9

Technology help can only control theft.

9

The more the technology , the more advanced are the theft techniques.

9

Theft is a social evil.

9

The only way to eradicate theft is by social awareness & the society as whole taking the responsibility for containing theft.
