BRPL BYPL
A loss journey from 61.89% ( BYPL) and 47.47% ( 53% - BRPL) to almost 10% ( FY 17-18).
BSES – Electricity Loss strategy
What is meant by 60% AT&C loss ??
If we buy 100 units and bill & collect money for 40 units, then our AT&C loss is 60%
How 60% loss can happen in a DESCOM ??Is major reason theft ?
It can happen if 60% consumers are involved in theft
It can happen if 100% consumers are involved in theft and are doing 60% theft !!
A loss reduction from 60% to 20% means sale up from 40% to 80% OR consumers will pay double !!!In 2004, BSES Delhi felt – it is “some thing Else”
– Need More Data

Major Loss Components
Technical loss
Energy which cannot be metered and billed due to loss in network
Prime reason is network quality and loading characteristics
Process loss
Energy accounting loss due to improper consumer registration, metering issue, meter reading and finally billing
Need Process strengthening
TheftLoss
Theft of electricity either by dishonest abstraction of energy through meter tempering or by direct theft of power.
a) Theft through meterb) DT- direct theftc)Accessories tampering
In order to reduce the loss, it is important to work on all three aspects.
Initial Strategies …….
100% Metering
100% consumer static metering.
All EHV, HT feeder metering with AMR ( 15 min data)
Meter on DT
Only static meters
Ease of new connectionSimplified documentation
Door step service
Vigilance investigation for case delayed / refusal
Consumer increased input decreased
Door to door survey
Basic assumption: Every body need power. Why some one is not taking power connection.
Found many cases of connection refusal, DT and unbilled meters.
DESCOM are used as law enforcing agencies., spl while releasing new connection. Need to take firm stand !!
BSES Metering Road Map
Metering System – The Guiding principles
Meter Replacement is a massive exercise –ensure long USEFUL life
The revenue loss due to faulty meter can be more than meter cost
Although Basic purpose of meter is Tariff implementation.But it generates lot of information
Energy meter is final interface with consumer
Meter is also called as cash box of Utility. Has to be planned properly

DT meter installation in BSES initiated in Year 2007
Present Key meter parameters– Phase wise Loading in kW or Amps– Loading values (monthly and 1/2 Hr slot wise)
Other parameters– Location of overload and underload DTs on GIS – Pole connectivity between DT
Analysis– Identification of DT with >80 % and >100 % loading– Overloading and underload at same location– LT Connection between overload and underload DTs– Scope of swapping of DTs (kVA rating dependent)
Additional meter parameters: a) Duration of loading
b) Monthly Loading (phase-wise)

Role of Meter in Loss Control
A BSES Concept
26Theft prevention and theft detection
Theft is both ART and Science
BSES Philosophy – Electricity Theft
What thief will try ………..
• Without damaging the meter• Without Detection• Theft can be done on “will”• Theft for a considerable Quantity• Theft which can not be proved
What is Theft?A deliberate attempt to steal “Considerable amount of energy” by ensuring no / low energy recording in the measuring device.
BSES Philosophy – Electricity Theft
How to control?
Study impact of theft rather than method of theft.
All theft leave evidence. Co-relate method with symptoms.
Theft Theory ………..Any Abnormal condition resulting to
• Slowing of meter• Switching OFF of meter• Can lead to data change
Are potential methods of theft
Kick Start ………..
As Abnormal conditions can result to meter tampering, It can also damage the meters.
Analysis of damaged / field removed meters can give vital clues.

So far…….
To prosecute tempering we need evidence !!
Yes ! As tempering means some abnormalities. If we can detect then we can detect tempering.
Every meter can be tempered. Important is can we catch all tempering.
There are thousand of method. Every day people find new method
By doing some abnormal action, one can do electricity theft
Analytics - How to Identify Theft ?
What is Analytics……To find Objective from Reality is the Analytics
•Meter do measurement
•Meter log events
DESCOM objective :
•Loss reduction•Network health• Reduce outage•Power quality
Meter Data is reality
Do Analytics forobjectives
Analytics - How to Identify Theft ?
AnalyticsTo study data to identify theft
Energy meter data analysis
To study of consumer meter data for abnormalities
Consumption analysis
To study the consumption trend
Billing database analysis
To study billing parameters
Secondary database analysis
To study the survey data
Analytics Philosophy
42
In Energy distribution business .. Healthy network, consumer getting
reliable & quality supply is NORMAL.
The OBJECTIVE of Analytics is to detect and study “ABNORMALITIES”.
For example: The Analytics OBJECTIVE is to find “Consumers not getting 230 +/-6% Volt rather, who all
are getting Rated voltage of 230V”.
Once Abnormalities are detected then determine CAUSE.
Successful theft creates abnormalities Basic electrical/ Voltage principal
Load related abnormalities Consumption pattern
Power Availabilities relatedOther sensor observationsMeter memory Data RelatedOther meter parameters
Behavior related
Using Analytics – Abnormalities can beidentified and cause (theft) can be detected
List of Abnormalities –Theft Detection

success rate
Theft Analytics – Maturity level 04Instantaneous Parameter
• Meters also log instantaneous parameters such as voltage, current, PF, power on/off etc.
• Analyze the instantaneous parameters pattern and variations to identify theft.
• Key is Logics - Relation between theft method and its impact on meter parameters.
• Once relations are established then it is easier to filter the cases.• Extensive knowledge of metering and electrical engineering is required.• Very high strike rate -- Wider acceptance by judiciary.
Today BSES has 132 LOGICS

Theft Analytics – Maturity level 05
Based on principal of Artificial Intelligence :Electricity theft is born out of human behavior, which is reflected in the consumption and electricity pattern recorded.
key question - can we use this concept for theft detection?when all we have is Just numbers??? The answer is - yes we can.
The 5th Maturity level is based on 2 basic principals:• For 2 events, having similar trend then it is expected that their outcome
will also be similar.• Utilities by now hold huge banks of meter data, consumption data,
secondary data information on successful and unsuccessful leads as identified through levels 1-4 of analytics.
Five Maturity Level of AnalyticsLevel 05
• A system born from experience and continued analysis.• A flexible system which learns from past issues, predicts the likely trends for future/unforeseen issues and
keeps learning from its experience.
Scope of Artificial Intelligence - concept can beextended
• To identify faulty meters & quality problem etc.• To identify consumers who may default• Consumers who will increase their load requirements etc.

Voltage drop in network
Key parameters
Voltage at Grid/DT end Voltage at Tail end consumer
DT & consumer location on feeder Analysis
Voltage drop represent the technical loss in network.
Higher voltage drop means network under stress
Variation of Vdrop with load change– input for Vregulation
Voltage drop is the easiest way to estimate technical loss & voltage regulations
Network Stress – comparing Tail end voltage
58
By controlling instantaneous voltage – MW Demand can be controlled
Typical thumb rule – 1% V effects 1.3% power consumption
PrincipalTypical consumer voltage 220
