Power Generation - An Overview
A thermal powerplant in Kolkata. India's largest super thermal powerplants have capacities of over 2,000 MW each.
India is the fifth largest electricity producing nation in the world. Power generation has grown over 100 fold since independence to 967 bn KWh in 2013-14. Nevertheless, power shortages (approx. 10 % of total demand) prevail due to inadequte utilization of capacity, loss making state utilities, lack of comprehensive inter regional transmission links and high transmission losses mainly due to theft. Thermal powerplants generate the bulk of the electricity produced in the country. Nuclear power capacity, currently at 4 780 MWe, is expected to be augmented in the future. The power sector has seen vast reforms especially after the passage of the Electricity Act 2003 including the formation of independent regulators like CERC.
Power Grid Corp. (PGCIL) operates the largest (95,000 circuit kms as on Jun 30 '12) grid sytems in the world and transmits over half of the total power generated (excl. captive) in India. India's captive power plants generated 68.2 bn kWh of electricity during 2003-04. Large captive power users include the aluminium, petrochemical and iron and steel industrial sectors.
17 825 MW of new power capacity was added to the grid in 2013-14. Renewable sources of energy, mainly wind and small hydro, contributed seven per cent of total electricity generation in 2006. The 2012-17 Five Year Plan set by the Government of India calls for an additional 88,500 MW of generating capacity in which the private sector will play a major role.
Over 82 per cent of the nearly 600,000 villages spread across India have been electified at the end of Aug 08.

Nuclear power generates less than 3 per cent of India's total electricity consumption. NPCIL, a public sector unit, operates 20 reactors at six nuclear plant sites across India. The total nuclear power capacity amounts to 5780 MWe and 32.5 billion kWh were generated in 2011-12. Seven reactors with a capacity to generate 5300 MWe are under various stages of construction. BHAVINI is constructing a 500 MWe Fast Breeder Reactor at Kalpakkam. Fast breeder technology uses spent fuel of plutonium and uranium from the Pressurised Heavy Water Reactors (PHWR, elsewhere known as CANDU) of the the other NPCIL plants. Uranium is mined by the Uranium Corp. of India Ltd. in Jaduguda, Jharkhand. The Nuclear Fuel Complex at Hyderabad fabricates the required nuclear fuel assemblies for the eventual generation of electricity. Thorium, due to large reserves in India, is also used used as nuclear fuel. New nuclear power plant clusters are plannedin collaboration with potential nuclear vendors such as Areva NP, GE-Hitachi, Westinghouse Electric and Atomstroyexport.

A small windfarm with four installed turbines with a capacity of about one MW at Frasergunj, along the West Bengal coast.
The NRSE (New and Renewable Sources of Energy) sector is set to provide 10 per cent of the installed capacity by 2012 although harnessing NRSE to its full potential would mean a capacity addition in the range of 100,000 MW. India has the fifth largest wind power generating capacity (~7 % global market share) in the world with an installed capacity of 19 881 MW at the end of Sept 2013, behind only China, USA, Germany and Spain. Tamil Nadu, Maharashtra, Karnataka, Gujarat and Rajasthan have the largest installed capacities of wind power facilities in India. Wind power potential is largest in the states of Andhra Pradesh, Gujarat, Karnataka, Rajasthan, as each has a potential to generate wind power in excess of 5,000 MW.

Other Renewable Sources of Energy (RES)
Other renewable sources of energy include small hydro projects (incl. tidal), solar, biomass gas, Biomass power and urban industrial waster power. The total generating capacity (incl. wind power and off-grid/captive power) amounted to 29 465 MW at the end of Sept 2013. Although wind energy holds a lion's share in the production of electricity among renewable sources of energy, bio-based power (agro residues & plantations), bagasse (sugar cane fibre residue) cogeneration and small hydro power plants (upto 25 MW) feed substantial amounts of electricity into the power grid. Solar energy based projects are being taken up at a rapidly increasing pace and it is projected that upto 1750 MW of solar power capacity (total capacity 2080 MW as at end of Sept 2013) will be added to the grid in 2014. The Jawaharlal Nehru National Solar Mission envisages 20 000 MW of solar power capacity in the national grid by 2020.
