Study on `Impact of Restructuring of SEBs’
APTRANSCO would manage only the transmission function. Though the
distribution function has been separated from APTRANSCO, the company is
still exercising control over the four DISCOMs, which is diluting the principle
of separating distribution function from transmission.
4.2.1 Reduction in Transmission Losses
APTRANSCO has achieved appreciable results in reducing transmission losses
as can be seen from the table below:

Reduction in losses over
1999-2000 (percentage points)
- 0.04 0.80 1.43 2.87 4.07
Reduction in losses from 8.98 per cent in 1999-2000 (i.e. the first year after
restructuring) to 4.91 per cent in 2004-05 indicates the significant efforts made
by APTRANSCO in this vital area. Strengthening of the transmission network
did not receive adequate attention in the integrated set-up of APSEB. After
restructuring, APTRANSCO has been able to pay better attention to
strengthening the transmission network. This has resulted in sizeable reduction
in transmission losses.
4.2.2 Operational Efficiency
Operational efficiency of the transmission system in Andhra Pradesh has
improved after restructuring, as can be seen from the reduction in transmission
losses in the last five years. The maximum and minimum frequency levels have
improved during the same period from 51.12 Hz and 47.80 Hz to 50.84 Hz and
48.62 Hz respectively.
The maximum and minimum voltages recorded at 132 kV level in 1999-2000,
(i.e. the first year after restructuring) were 129 kV and 92 kV respectively. By
2004-05, the maximum and minimum voltages at 132 kV level have improved
to 140 kV and 121 kV respectively. This indicates the improvement in the
voltage levels of the transmission system.
The availability of the transmission system and the cost recovery after
restructuring are indicated in the table below:
