BSES Philosophy – Electricity Theft
How to control?Theft Theory ………..Any Abnormal condition resulting to
Study impact of theft rather than method of theft.
All theft leave evidence. Co-relate method with symptoms
• Slowing of meter• Switching OFF of meter• Can lead to data change
Are potential methods of theft Co relate method with symptoms.Are potential methods of theft
Kick Start ………..
As Abnormal conditions can result to meter tampering,
It can also damage the meters.g
Analysis of damaged / field removed meters can give vital clues.
Theft policing !!! key enablers

BSES has installed AMR modems for all premium consumers
Presently 15,000 consumers are covered through AMR
Plan to further extend AMR to 0.1 Million consumers

Secondary data collected from various sources.
Secondary Data Analysis
The data available in the secondary data are reconciled in billing database to conclude unbilled cases.
For example , through internet sites of Reserve bank of India & all For example , through internet sites of Reserve bank of India & all other banks operating in India, list of all bank branches operating in our service area was obtained.
This list was reconciled with the billing database to confirm that all b k b h b i bill dbank branches were being billed.
To our surprise we found around 1% of the bank branches were not in the billing net.
Secondary data analysis – a useful tool for tariff misuse
Logics development is a continuous exercise
