The fifth largest source of electricity in India is Nuclear Power after thermal, hydroelectric and renewable sources of electricity. Currently, there are 22 Nuclear Power Plants in India operating in seven states with 6780 MegaWatt (MWe) out of which 18 reactors are Pressurised Heavy Water Reactors (PHWRs) and 4 are Light Water Reactors (LWRs). The responsibility for generating nuclear power in India lies with the Nuclear Power Corporation of India Limited (NPCIL), a public sector enterprise headquartered in Mumbai. NPCIL functions under the administrative control of the Department of Atomic Energy, Government of India.
Nuclear Power Plants in India
Nuclear Power Plants in India play an important role in energy resources which ensure a balanced and sustainable power supply.
