Power sector of Andhra Pradesh
Power sector of Andhra Pradesh is divided into 4 categories namely Regulation, Generation, Transmission and Distribution. Andhra Pradesh Electricity Regulatory Commission (APERC) is the regulatory body.
Under the program of installing 500
The newly formed Andhra Pradesh Green Energy Corporation Limited (APGECL), a 100% subsidiary of APGENCO, will be the trading agency/licensee for the 10 GW solar project in a phased manner and for connecting it to the grid.[14] The 10 GW solar projects would be used to meet the entire agriculture power consumption which will be met during the day time for nine hours duration daily.[15] Andhra Pradesh is also leading in installation of solar power /off grid agriculture pump sets.[16] A renewable energy export policy for Andhra Pradesh was also announced to facilitate the setting up of 120 GW solar, wind and solar-wind hybrid energy parks by using 0.5 million acres of land.[17] New & Renewable Energy Development Corporation of Andhra Pradesh (NREDCAP), a state owned company, is actively involved in promoting renewable energy projects in the state.[18] Roof top solar power cost/unit in the state are falling below the domestic power tariff.[19]
The total installed utility power generation capacity is nearly 24,854 MW in the state as of 31 March 2020
Short term power purchases
APDisComs purchase regularly from the energy exchange, etc. to meet the peak load and energy shortages. As the power purchases/sales are done on daily basis without proper planning and optimum utilization of APGENCO power generation capacity, APERC has given guidelines to the DisComs for implementation while making short term (less than one year duration) purchases and sales in the year 2022.[26][27]
Non-renewable
Thermal power
Currently operating coal based thermal power plants in Andhra Pradesh are listed below.[29][30]
Gas fuel-based
The following are the list of presently installed combined cycle gas turbine power plants and diesel engine power plants in the state. However many of these power plants are not operating due to non-availability of natural gas and high cost of liquid fuels.[32]

Pumped storage hydroelectricity projects
The water reservoir of a PHES is created by building
Polavaram right bank PHES: A 103,000
Srisailam right bank PHES: A 77,000 MW PHES project is feasible with an upper reservoir, located on the right bank side within 1000 m distance of Srisailam reservoir, with 87 tmcft live storage at 650 m msl FRL. The reservoir bunds are constructed on 500 m msl contour line by 155 m high and the water surface area of the upper reservoir is nearly 20 km2. The adjacent Srisailam reservoir at FRL 270 m msl with 185 tmcft live storage is the lower reservoir with perennial water source. The average water head available is 340 m with provision to draw water from the Srisailam reservoir by the PHES units located in semi open or underground power houses. The PHES project can produce 308 billion KWh at 4000 hours/year or 12 hours/day operation in generation mode. Only 43.5 tmcft (50%) reservoir storage is used for power generation on daily basis and the remaining half kept as buffer storage to compensate the loss of storage in downstream reservoir due to PHES by releasing water once in a year in to the Srisailam reservoir to meet irrigation water requirements. The buffer storage is replenished later at the earliest during the monsoon/floods. This PHES can also moderate the severe floods by utilizing empty volume kept in the lower reservoir or operating in pump mode (maximum 10 lakh cusecs) to fill the upper reservoir.

The stored water is also used as carryover storage to meet water shortages in drought years. The PHES pumps flood water @ 23,000 cusecs from the Vamsdhara river during the monsoon months and works as PHES the rest of the year. Buffer storage 0.5 tmcft included.

Notes: Power potential (MW) is in generation mode, MDDL→ Minimum Draw Down Level or lowest bed level of the reservoir, FRL→ Full Reservoir Level, m msl→ meters above mean sea level. The total water storage includes nearly 432 tmcft of irrigation components. PHES water storage is 793 tmcft only. The PHES land requirement is nearly 1% of the land required (41,250 km2) for equivalent electricity generation by Solar PV power plants.[55] The power potential doubles in case of pumping operation for six hours in a day for the same water storage.
Solar
The state is endowed with vast photovoltaic power potential on its marginally productive lands.[73] The state has total installed solar power capacity of 4,116.01 MW as of 30 June 2021.[38][74][75][76][77]
The state is planning to add 10,050 MW solar power capacity to provide power supply to farming sector during the day time.[78][79] Out of 10,050 MW, 6,400 MW capacity at 10 sites were offered for bidding. The winning tariffs are Rs 2.50 per unit which are at least 25% more than the earlier awarded tariffs of Rs 2 per unit in November 2020 even after reducing scope of work (no HV transmission line construction outside the solar park), state providing the land on lease, giving state guarantee for the timely payment for the power sold, allowing the state guarantee as security to get financial assistance at lower interest rates, disregarding higher solar power potential at these sites compared to Western and northern regions, etc.[80][81] The AP high court has stayed the award of contracts to the successful bidders on the grounds that these contracts are excluded from the jurisdiction of APERC in contravention of the electricity act, 2003.[82][83]
The state has offered five Ultra Mega Solar Power Projects with a total capacity of 12,200 MW to developers under renewable power export policy outside the state.[84][85][86][87][88]
