India - World Nuclear Performance Report

India has 23 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 July 2023 the first Indian-designed 700 MWe pressurized heavy water reactor (PHWR), Kakrapar 3, entered commercial operation. In February 2024 the second 700 MWe PHWR at the site, Kakrapar 4, was connected to the grid. India has a further two 700 MWe PHWR units under construction at Rajasthan, and the government has sanctioned construction of a further ten: Kaiga 5&6 in Karnataka; Gorakhpur 3&4 in Haryana; Chutka 1&2 in Madhya Pradesh; and Mahi Banswara 1-4 in Rajasthan. 

In April 2023 the government announced plans to increase nuclear capacity, with nuclear accounting for nearly 9% of India's electricity by 2047, up from around 3% currently. In August 2023 the Minister of State said the government is exploring options for small modular reactors but that large-size plants remain the mainstay of the country’s plans to expand capacity.
