Study on `Impact of Restructuring of SEBs’
It can be seen from the above that there is a significant improvement in the
power supply position in recent years. At present, there are no load shedding
and also there are no restrictions on industrial consumers.
4.3.2 Distribution losses
The reduction of losses in the distribution system (both technical and
commercial) are shown in the following table:
Distribution Losses (%)
Reduction of
DISCOM
2000-01 2001-02 2002-03 2003-04 2004-05
Losses in last four
years (% point)
SPDCL N.A. 21.31 21.22 19.34 18.12 3.2
NPDCL 26.81 23.28 21.24 20.24 19.20 7.6
CPDCL N.A. 27.10 23.29 20.63 20.17 6.9
EPDCL 17.90 17.30 16.80 15.30 N.A. 2.6
It is observed that the losses in all the four DISCOMs are coming down
gradually. The loss levels in NPDCL and CPDCL are high and the reduction in
the losses achieved is also substantially high at around seven per cent. The
losses in the EPDCL are the lowest at 15.3 per cent. SPDCL has brought down
the losses from 21.31 per cent in 2001-02 to 18.12 percent in 2004-05. All the
DISCOMs have brought down the distribution losses.
4.3.3 Transformer failures
The transformers failure rate (%) in the DISCOMs are as indicated below:

Power transformers N. A. N. A. N. A. N. A.
Distribution transformers 14.16 9.26 8.45 7.01
NPDCL

Distribution transformers 24.42 18.83 15.81 11.72

EPDCL
Power transformers 6.13 5.61 2.03 N.A
Distribution transformers 13.87 9.48 7.25 N.A
It can be seen from the above, that there is a reduction in the transformer
failures (both power as well as distribution transformers) in the DISCOMs. In
the case of NPDCL and CPDCL, though the reduction in distribution
transformer failures is substantial, the percentages of failures at the end of
