The '''Andhra Pradesh Power Generation Corporation Limited (APPGCL)''' is power generating organization in [[Andhra Pradesh]]. It undertakes operation and maintenance of the power plants and also setting up new power projects alongside upgrading the project's capacity,<ref name="overview">{{cite web|url = http://apgenco.gov.in/inner.asp?frm=corporate_profile|title = APGENGO overview|accessdate = 19 June 2014|publisher = APGENCO|archive-url = https://web.archive.org/web/20140714175220/http://apgenco.gov.in/inner.asp?frm=corporate_profile|archive-date = 14 July 2014|url-status = dead}}</ref> under the recommendations of Hittenbhayya committee setup by TDP Govt.

==History==

The government reforms in power sector led to the formation of APGENCO on 28 December 1998 and commenced operations from 1 February 1999.<ref name=overview /> 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.<ref name=apseb>{{cite web|title=History of APSEB |url=http://www.npli.in/transco/about-us/about-aptransco |archive-url=https://web.archive.org/web/20140714181001/http://www.npli.in/transco/about-us/about-aptransco |url-status=dead |archive-date=14 July 2014 |publisher=Transmission Corporation of AP |access-date=19 June 2014 }}</ref>

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.<ref name=apseb />

== 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 State Power Generation Corporation Limited|Telangana Power Generation Corporation Limited]] (TGGENCO) was formed for the newly formed [[Telangana]] state and APGENCO remained for Andhra Pradesh in accordance with the [[Andhra Pradesh Reorganisation Act, 2014]].<ref name="power plants">{{cite web|author1=Sudheer Goutham|title=Power plants division between Andhra Pradesh and Telangana|url=https://www.deccanchronicle.com/140530/nation-current-affairs/article/existing-power-plants-be-divided-between-andhra-pradesh|work=Deccan Chronicle|access-date=7 June 2014|date=30 May 2014}}</ref>

== Power plants ==
The total installed capacity of APGENCO, after the state's bifurcation is 6389 MW comprising 4210 MW Thermal, 1747.60 MW Hydro and 405.40 MW Solar 
power plants.<ref>[http://www.aptransco.gov.in/transco/docs/Salient-Feb-15.pdf Salient features of AP TransCo.

Though the performance of APGenCo thermal power stations in terms of reliability, availability and maintainability ([[RAMS|RAM]] analysis) is one of the best in India,<ref>{{cite web |url=http://www.apgenco.gov.in/|title=  APGenCo website main page|access-date=23 June 2014}}</ref> its hydro power stations performance is satisfactory.monsoon season.<ref>{{cite web |url=http://www.siasat.com/english/news/power-house-srisailam-submerged|title=  Power house at Srisailam submerged|access-date=23 June 2014}}</ref> 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 '[[Load following power plant|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%.<ref>[http://www.indiawaterportal.org/articles/managing-historic-flood-krishna-river-basin-experience-averting-catastrophe-apwrdc Managing historic flood in the Krishna river basin in the year 2009]</ref>
