Synopsis of State Reports (Vol.-IV)
Study on `Impact of Restructuring of SEBs’
The efficiency improvements, after restructuring, are as under:
• Plant load factor (PLF) of thermal power stations improved from 77.6 to
89.7 per cent;
• Plant availability has improved from 84.8 to 92.5 per cent;
• Secondary oil consumption level has come down from 1.7 ml/kWh to 0.50
ml/kWh;
• Auxiliary consumption in thermal power stations has come down from
9.17 to 9.09 per cent;
• Annual electricity generation has increased from 27,000 MU to 29,000
MU; and
• APGENCO has been registering profits right from its inception. The profit
after tax (PAT) for 2002-03, 2003-04 and 2004-05 have been Rs 55.73
crore, Rs 10.46 crore and Rs 51.64 crore respectively.
During 2003-04, the profit came down on account of the poor inflows into the
Srisailam and Nagarjuna Sagar reservoirs.

APTRANSCO is one of the best performing transmission companies in the
country. It has made sizeable investments to strengthen the transmission
network.
