Synopsis of State Reports (Vol.-IV)
Study on `Impact of Restructuring of SEBs’
been noticed in the performance of the Utilities after the restructuring. The
same are analysed hereunder:
(a) Power Supply Position: There were severe peak demand shortages
(ranging from 800 to 1,100 MW) and energy shortages (ranging from 560
to 2,300 MU) in APSEB before 1998-99. This resulted in load sheddings,
leading to load restrictions on industrial consumers in addition to
unscheduled interruptions. The situation has largely improved in view of
the scaling down of the peak demand and energy shortages by way of
capacity additions and improved plant performance. In the postrestructuring
scenario, peak demand shortages range from 4 to 110 MW
and energy shortages from 25 to 500 MU in different years.
(b) Distribution Losses: The DISCOMs have achieved considerable
reduction in distribution losses (both technical and commercial). The
losses for the years 2001-02 to 2004-05 are shown in Table below.
Table 1.7: 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
(c) Transformer Failures: There is substantial reduction in the failure rate of
DTs after the restructured Utilities came into existence. The position is
indicated below:
Table 1.8: Distribution Transformers Failure Rate
DISCOM
Distribution Transformers Failure Rate (%)
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.
