1. Making mapping / Data of Distribution Line

Mapping of complete primary and secondary distribution system with all parameters such as conductor size, line lengths etc.

Compilation of data regarding existing loads, operating conditions, forecast of expected loads etc. Preparation of long-term plans for phased strengthening and improvement of the distribution systems along with transmission system.

2. Implementation of energy audits schemes

It should be obligatory for all big industries and utilities to carry out Energy Audits of their system.

Further time bound action for initiating studies for realistic assessment of the total T&D Losses into technical and non-technical losses has also to be drawn by utilities for identifying high loss areas to initiate remedial measures to reduce the same.

The realistic assessment of T&D Loss of a utility greatly depends on the chosen sample size which in turn has a bearing on the level of confidence desired and the tolerance limit of variation in results.

In view of this it is very essential to fix a limit of the sample size for realistic quick estimates of losses.

3. Mitigating power theft by Power theft checking Drives

Theft of electric power is a major problem faced by all electric utilities. It is necessary to make strict rule by State Government regarding Power theft. Indian Electricity Act has been amended to make theft of energy and its abatement as a cognizable offense with deterrent punishment of up to 3 years imprisonment.

The impact of theft is not limited to loss of revenue, it also affects power quality resulting in low voltage and voltage dips.

Required to install proper seal management at Meter terminal Box, at CT/PT terminal to prevent power theft. Identify Power theft area and required to expedite power theft checking drives. Installation of medium voltage distribution (MVD) networks in theft-prone areas, with direct connection of each consumer to the low voltage terminal of the supply transformer.

All existing unmetered services should be immediately stopped.

4. Replacement of Faulty/Sluggish Energy Meter

    It is necessary to replacement of Faulty or sluggish Meter by Distribution Agency to reduce un metered Electrical energy.
    Required to test Meter periodically for testing of accuracy of meter. Replacement of old erroneous electromechanical meters with accurate Electro static Meter (Micro presser base) for accurate measurement of energy consumption.
    Use of Meter boxes and seals them properly to ensure that the meters are properly sealed and cannot be tampered.


5. Bill Collection facility

    Increase Bill’s Payment Cells, Increasing drop Box facility in all Area for Payment Collection.
    E-Payment facility gives more relief to Customer for bill Payment and Supply agency will get Payment regularly and speedily from Customer.
    Effectively disconnect the connection of defaulter Customer who does not pay the Bill rather than give them chance to pay the bill.


6. Reduce Debit areas of Sub Division

Recovery of old debts in selected cases through legal, communication and judicial actions. Ensuring police action when required to disconnect connection of defaulter Consumer.

7. Watchdog effect on users

Users must aware that the distribution Agency can monitor consumption at its convenience. This allows the company fast detection of any abnormal consumption due to tampering or by-passing of a meter and enables the company to take corrective action.

The result is consumer discipline. This has been shown to be extremely effective with all categories of large and medium consumers having a history of stealing electricity. They stop stealing once they become aware that the utility has the means to detect and record it.

These measures can significantly increase the revenues of utilities with high non-technical losses.

8. Loss Reduction Programmed

The increased hours of supply to Agriculture and Rural domestic consumers have resulted in higher loss levels
