The Department of Atomic Energy reports that nuclear power generation in India accounts for approximately 3% of the total electricity generation, with 3.1% recorded in 2024-25. The initial slow expansion was attributed to technological embargoes and limited resources. Currently, India's installed nuclear power capacity is 8.78 GW (excluding RAPS-1, 100 MW). The plan is to increase this to 22.38 GW (excluding RAPS-1, 100 MW) by 2031-32 through the deployment of indigenous 700 MW reactors and 1000 MW reactors with international cooperation. The government has set a Nuclear Energy Mission target of 100 GW by 2047. Foreign Direct Investment (FDI) is currently prohibited in atomic energy, but the government intends to amend the Atomic Energy Act, 1962, to enable private sector involvement.

Nuclear power generation in the country has kept pace with the overall generation of electricity in the
country, and thus has consistently remained at about 3%. The nuclear share in total electricity generation
in the country in 2024-25 was about 3.1%.
The main reason for slow expansion of nuclear power capacity in the early days was the technology
development phase that had to be gone through in an international embargo and technology denial regime,
coupled with limited availability of resources. Therefore, although India operates the sixth largest nuclear
reactor fleet in the world, the present installed capacity of nuclear power is 8.78 GW (excluding RAPS-1,
100 MW). Now indigenous PHWR technology has matured for larger size reactor, i.e 700 MW. With the
deployment of indigenous 700 MW reactors and 1000 MW reactors with international cooperation, the
present capacity will increase to 22.38 GW (excluding RAPS-1, 100 MW) by 2031-32 on progressive
completion of projects at various stages of implementation. Further, the Government has also announced
the Nuclear Energy Mission of reaching 100 GW by 2047.
As per the current policy, foreign direct investment (FDI) in atomic energy is prohibited. Government is
proposing to amend Atomic Energy Act, 1962 to allow private sector participation in atomic energy.
