The Nuclear Power Corporation of India Limited (NPCIL) is an Indian public sector undertaking based in Mumbai, Maharashtra.

It is wholly owned by the Government of India and is responsible for the generation of electricity from nuclear power.

NPCIL was created in September 1987 under the Companies Act 1956, "with the objective of undertaking the design, construction, operation and maintenance of the atomic power stations for generation of electricity in pursuance of the schemes and programmes of the Government of India under the provision of the Atomic Energy Act 1962."

NPCIL was the sole body responsible for constructing and operating India's commercial nuclear power plants until the setting up of BHAVINI Vidyut Nigam in October 2003.

As of December 2024, the company had 24 nuclear reactors in operation at seven locations, a total installed capacity of 8180 MWe.
