Prasad Sr. Assistant Professor, Department of EEE, GMR Institute of Technology, RAJAM, Srikakulam District, Andhra Pradesh, INDIA ABSTRACT Andhra Pradesh State Electricity Board (APSEB) similar to other SEBs in the country, was formed on 01 April, 1959 under the provisions of Electricity (Supply) Act 1948, had been responsible for power generation, transmission, and distribution and for the overall development of the power sector in A.P. Andhra Pradesh State Electricity Board was restructured as Andhra Pradesh Power Generation Corporation (APGENCO) to look after generation and Andhra Pradesh Power Transmission Corporation (APTRANSCO) to look after transmission and distribution and sale of electricity in the state of Andhra Pradesh from The Eastern Power Distribution Company of AP Limited (APEPDCL) came into existence from April 1 st, 2000 as a result of dismantling of vertically integrated Andhra Pradesh State Electricity Board (APSEB) into functionally distinct entities undertaking Power Generation, Transmission and Distribution. The present study aims primarily to evaluate the profile and performance of APEPDCL. The study also focuses on the origin and development of power sector in Andhra Pradesh. Keywords--- APEPDCL, Power Sector, Sale of Energy, Revenue I. INTRODUCTION The power sector has registered significant progress since the process of planned development of the economy began in Hydropower and coal based thermal power have been the main sources of generating electricity. Nuclear power development is at slower pace, which was introduced, in late sixties. Indian power sector is witnessing major changes. Growth of power sector in India since its independence has been noteworthy. Over the years, Andhra Pradesh has been experiencing severe power shortages and more than half of the additional capacity being established in Andhra Pradesh is from Independent Power Producers who need to finalize financial closures with national and international financiers for securing adequate finance for their projects. These developers have, in the past, been seeking resource to a State Government guarantee and Central Government counter-guarantee to cover the Andhra Pradesh State Electricity Board s (APSEB) payment obligations. However, given the sheer magnitude of the power purchasing liability, and the existing constraints on the state s financial resources, which are expected to persist over the near and medium term, it is inconceivable that the comfort of guarantees as above can continue to be extended. It, therefore, became imperative to radically restructure the APSEB to convince financiers and lending agencies, of its financial sustainability over the medium and long term. In line with these developments, the State Legislative Assembly has enacted the Andhra Pradesh Electricity Reforms Act, 1998, which has received the President s assent and has become effective from February 1, Under the provisions of the Reforms Act, APSEB will initially be restructured into two functionally focused entities Andhra Pradesh Generation Corporation Limited (APGENCO) for generation activities and Transmission Corporation of Andhra Pradesh Limited (TRANSCO) for transmission and distribution activities. To provide functional autonomy and transparency, GENCO and TRANSCO are incorporated under the Companies Act. II. OBJECTIVES OF THE STUDY The present study aims: To study the evolution of power sector in Andhra Pradesh. To give a brief profile of APEPDCL. 539 Copyright Vandana Publications. All Rights Reserved.

RESEARCH METHODOLOGY This study is based on the secondary data which is collected from the various reports and websites of APTRANSCO, APEPDCL, Ministry of Power (GoI), research papers, journals, magazines, periodicals, newspapers and internet etc. IV. POWER SECTOR IN ANDHRA PRADESH In Andhra Pradesh, private energy establishments started to supply power from the middle of 1950 s to Visakhapatnam, East Godavari and West Godavari districts. In Krishna District, Vijayawada and Machilipatnam were electrified in 1930 and 1933 respectively while Guntur was electrified in 1932, Narasaraopet in 1936 and Ongole in APSEB has started to supply electricity to all these places since Private Power Establishments had supplied Electricity to Nellore from 1934, Thermal Power Station from 1950, Machkund from 1956 and Tungabadra from Though low electric supply had been provided to Anantapur from Mysore since 1933, it got gradually improved by Electricity was supplied to Hindupur from 1958 and to all taluks of Anantapur from Electricity from Private Sector was first provided to Proddutur in 1936 in Cuddapah (Now called Kadapa) District; later Hydel Power was supplied from Tungabadra in 1957, while Pulivendula, Badvel and Rajampet were electrified in 1955, Kamalpuram in 1957 and Nandyal in By 1965 all the towns in Cuddapah with L.T. and H.T. had been supplied power. Government took over electric supply to Kurnool from Jog falls in Markapur and Cumbum had been provided electricity from the diesel power stations established in 1957, Srisailam was electrified by 1963, and by 1965 power was extended to 216 villages. In Chittor a private power supply company brought power from Vellore to Chittor and by 1965 hydel power stations of Tungabadra started supplying power to the entire district. Power supply had enormously increased to Hyderabad from 35,000 K.W. to 72,000 K.W. by Extension of power to villages was started in 1956 reaching 221 villages by March Nizamabad had power supply from 1933 with its extension to Nizamsagar in Adilabad had been supplied power from Sirpur Paper Mill Ltd. from , till it was connected to Ramagundam Thermal station in Medak had no power supply until , which was supplied by Rural Electrification Corporation in 1955 and by March 1960 the entire district had been provided with power supply. Nalgonda had no power supply until Warangal was electrified in 1936 getting power supply from Azamshahi Mills, later from Kothagudem Super Thermal Station with its four stations at Warangal, Janagam, Mylaram and Marripeda. Khammam had been electrified in 1950, when a Diesel Power Station was established it was later connected to Kothagudem Thermal Station. Another Diesel Power Station was established in 1950 in Karimnagar to supply electricity, which waslater connected to Ramagundam in Mahabubnagar had been supplied electricity from Narayanapet during , till APSEB took over it in with three small diesel generators, extending power supply to all taluk headquarters by V. ANDHRA PRADESH STATE ELECTRICITY BOARD (APSEB) Andhra Pradesh State Electricity Board (APSEB) similar to other SEBs in the country, was formed on 01 April, 1959 under the provisions of Electricity (Supply) Act 1948, had been responsible for power generation, transmission, and distribution and for the overall development of the power sector in A.P. But, due to various unpredicted and undesired reasons, the power sector in A.P. had got deteriorated. However with the implementation of reforms recommended by Hitten Bayya Committee (1995) and later with the comprehensive report A.P. Agenda for Economic Reforms (1997) suggested by the World Bank, the dwindling state of APSEB has got set right. Andhra Pradesh State Electricity Board was restructured as Andhra Pradesh Power Generation Corporation (APGENCO) to look after generation and Andhra Pradesh Power Transmission Corporation (APTRANSCO) to look after transmission and distribution and sale of electricity in the state of Andhra Pradesh from APGENCO is engaged in the business of generation of electricity apart from the execution of the ongoing and new power projects under capacity addition programme and taking up renovation and modernization works of the old power stations. The installed capacity of APGENCO as on was MW comprising MW thermal, 3132 MW Hydro and 2 MW wind power stations and contribute about 60 per cent of the total power system demand. APGENCO occupies the third position in India as far as the thermal power generation is concerned with a plant load factor of 86.3 percent. Further, unbundling of APTRANSCO into APTRANSCO and 4 Distribution Companies (APEPDCL, APSPDCL now it is TSSPDCL, APCPDCL and APNPDCL now it is TSNPDCL) under Second Transfer 540 Copyright Vandana Publications.
