Power sector of andhra pradesh – wikipedia electricity will not generally cause


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. [1] APGENCO deals with the electricity production and also maintenance, proposes new projects and upgrades existing ones as well. [2] The APGENCO also set up a Special Purpose Vehicle (SPV), named as Andhra Pradesh Power Development Company Limited (APPDCL), a joint venture company of APGENCO (with 50% equity) and IL&FS (50% equity) to set up Krishnapatanam thermal power project (2×800 MW). [3]

APTRANSCO is set up for transmission of power. [4] Power distribution in the state is divided into two divisions, namely Eastern Power Distribution Corporation Limited (EPDCL) and Southern Power Distribution Corporation Limited (SPDCL), which distributes the power to the households and the industries. [5] APGENCO, APPDCL, NTPC and other private firms contribute to the generation of power in the state of Andhra Pradesh. [6] [7] Andhra Pradesh has become the second state in India to achieve 100% electrification of all households. [8] Weighted average cost of power generation and purchases is INR 3.16 per kWh which is highest in the country. [9]

The total installed utility power generation capacity is nearly 23,051 MW in the state. [10] APtransCo has made long term power purchase agreements for 17,303 MW as of 28 Febrauary 2018. [11] The per capita electricity consumption is 1085 units with 55,160 million KWh gross electricity supplied in the year 2016–17. [11] [12] The performance of Krishnapatanam thermal power station (2X800 MW) with super critical pressure technology is not satisfactory even after one year commercial operation as the units rarely operate at rated capacity forcing the state to purchase costly power from day ahead trading in IEX. [13] [14]

The state has well spread transmission system. APTransCo / DisComs owned and operated transmission lines from 400 kV to 11 kV are 231,127 circuit kilometres excluding the HT lines owned and operated by PGCIL in the state. [37] [38] For importing and exporting power, the state grid is well interconnected with adjoining western and eastern regional grids in addition to adjoining state grids. [39] The spread of high voltage transmission lines (≥ 11 kV) is such that it can form a square matrix of area 1.93 km 2 (i.e. on average, at least one HT line within 0.7 km vicinity) in 160,205 km 2 total area of the state. DisComs owned and operated LT lines (below 11 kV) are 292,158 circuit kilometres. It represents that there is at least one HT or LT line availability on average within the vicinity of 306 meters in the entire state area. The state has 3183 nos substations (≥ 33 kV) which represents one substation in every 50.33 km 2 area on average (i.e. one substation with in 3.6 km distance on average). [11] However the maximum peak load met is 8909 MW as of 28 February 2018. [11] Huge installed capacity of the transmission network and the substations is being underutilized with low demand factor.
