1.5.3 Distribution
2004-05. It would be seen that both the maximum and minimum
frequencies have been brought closer to the standard figure of 50 Hz.
With the separation of electricity distribution function from APTRANSCO,
four DISCOMs came into existence from the year 2000. Several improvements
have been noticed in the performance of the Utilities after restructuring.
The companies have achieved considerable reduction in distribution losses. The
position in the last four years is shown below:
Reduction in Distribution Losses
DISCOM
Distribution Losses (%)
2001-02 2004-05
SPDCL 21.31 18.12
NPDCL 26.81 19.20
CPDCL 27.10 20.17
EPDCL 17.90 15.30
After restructuring of APSEB, the failure rate of distribution transformers
(DTs) has been brought down substantially. This is evident from the table
given below:
Distribution Transformers Failure Rate (%)
DISCOM 2001–02 2002–03 2003–04 2004–05
SPDCL 14.16 9.26 8.45 7.01
NPDCL 24.42 18.83 15.81 11.72
CPDCL N.A. 16.27 11.87 9.48
EPDCL 13.87 9.48 7.25 N.A.
Since a large number of DTs have been added in the system and High Voltage
Distribution System (HVDS) has also been adopted, the failure rate is likely to
go down further. Addition of new DTs will also result in relieving the
overloaded DTs.
The improvements made in metering by the DISCOMs are:
• All categories of services, except agricultural, are provided with meters.
Almost 100 per cent services in these categories have been metered.
• Metering of agricultural services is 21 per cent in SPDCL, 8 per cent in
EPDCL and 2 per cent in the other two DISCOMs.
