History

The government reforms in power sector led to the formation of APGENCO on 28 December 1998 and commenced operations from 1 February 1999.[2] The imbalance of the revenues against the cost of production, no significant reduction in technical losses and energy thefts, high cost purchases from IPP's, other SEB's gradually worsened the financial position of APSEB.

APSEB division

Government of Andhra Pradesh realizing the declining tendency of the financial position of APSEB and considering the recommendations made by committee it was unbundled into Andhra Pradesh Power Generation Corporation (APGENCO) & Transmission Corporation of Andhra Pradesh Limited (APTRANSCO) on 1 February 1999 by AP Electricity REFORMS ACT.[3]

APTRANSCO was further unbundled w.e.f. 1 April 2000 into "Transmission Corporation" and four "Distribution Companies" (DISCOMS). From Feb 1999 to June 2005 APTransco remained as single buyer in purchasing and selling of power to DISCOMs.[3]

APGENCO formation and split

Later, on 2 June 2014, when the state was bifurcated, APGENCO distributed all the assets, liabilities and power stations to both the states and Telangana Genco (TSGENCO) was formed for the newly formed Telangana state and APGENCO remained for Andhra Pradesh in accordance with the Andhra Pradesh Reorganisation Act, 2014.[4]

Power plants

The total installed capacity of APGENCO, after the formation of TSGenCo is 4559.6 MW comprising 2810 MW Thermal, 1747.6 MW Hydro and 2 MW Wind power stations.[5] The Power Plants of APGENCO include thermal, hydel and wind based plants.[6][7]

Operational performance
See also: Srisailam Dam §  Power generation optimization
See also: Nagarjuna Sagar Dam §  Power generation

Though the performance of APGenCo thermal power stations in terms of reliability, availability and maintainability (RAM analysis) is one of the best in India,[9] its hydro power stations performance is satisfactory.monsoon season.[10] The thermal efficiency (heat rate) of thermal power stations is quite remarkable. Operating the thermal power stations in the range of 75 to 100% capacity in 'frequency follow mode' with good part load efficiency is the needful strategy in surplus electricity grid except during peak demand hours. Also Hydro power stations should perform well meeting all the functions such as power factor correction, peaking power generation, pumping water in pump mode and secondary power generation during monsoon season utilising total available water. This can be achieved by maintaining hydro power stations at availability more than 95%.[11]
