India nuclear operable reactors, share of generation

India has 24 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 March 2025 the third Indian-designed 700 MWe pressurized heavy water reactor (PHWR) was connected to the grid at Rajasthan. This follows the first two PHWR-700 units that commenced operation at Kakrapar in 2021and 2024. India has a further 700 MWe PHWR unit 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 2025 an EPC (engineering, procurement and construction) contract for Kaiga 5&6 was awarded to Megha Engineering & Infrastructure, and in May India’s regulator gave siting consent for the four units planned at the Mahi Banswara site. Four Russian-designed reactors are also under construction at Kudankulam. 

In April 2023 the government announced plans for nuclear to account for nearly 9% of India's electricity by 2047, up from around 3% currently. In February 2025 the country’s Minister of Finance Nirmala Sitharaman said that this would require the “development of at least 100 GW of nuclear energy by 2047.”

The government is also pursuing SMRs. In January 2025 NPCIL issued a request for proposals from private entities to finance and build a fleet of SMRs. In February 2025 a "nuclear energy mission for research & development of small modular reactors (SMRs) with an outlay of Rs. 20,000 crore,” [about $2.3 billion] was announced with the aim of developing at least five SMRs by 2033.
