India has 22 reactors at seven nuclear power plants located both inland and along the coast. The majority of reactors are indigenously-designed pressurized heavy water reactors (PHWRs).

In April 2023 the government announced plans to increase nuclear capacity from 6780 MWe to 22,480 MWe by 2031, with nuclear accounting for nearly 9% of India's electricity by 2047.

Two VVER-1000 reactors at the Kudankulam nuclear power plant, located in Tamil Nadu, began commercial operation in 2013 and 2017, respectively. Four additional VVER-1000 units are under construction at the site: units 3&4 began construction in 2017; unit 5 in June 2021; and unit 6 in December 2021. All four units are expected to be completed by 2027.

Kakrapar is an indigenously-designed plant in India's Gujarat state with three operating reactors and one under construction. Unit 3 – India’s first PHWR-700 – was connected to the grid in January 2021 but has still not reached commercial operation (as of June 2023). Units 3&4 began construction in 2010 and 2011, respectively.

Two further PHWR-700 units are under construction at Rajasthan 7&8 and in May 2023 a ‘supplementary joint venture agreement’ was signed between NTPC – the country's largest power company – and Nuclear Power Corporation of India Ltd (NPCIL) for the development of six PHWR-700 units: two at Chutka in Madhya Pradesh and four at Mahi Banswara in Rajasthan.
