New Delhi, July 23: India’s largest nuclear power station at Kudankulam in Tamil Nadu is set to expand its capacity significantly, with four additional reactors under various stages of construction, according to Dr Jitendra Singh, Union Minister of State (Independent Charge) for Science & Technology and Atomic Energy. The information was provided in a written reply in the Lok Sabha on Wednesday.
Currently, Kudankulam Nuclear Power Plant (KKNPP) operates two units (Unit 1 & 2), each with a capacity of 1000 MW, contributing a total of 2000 MW to the national grid.
Current Power Allocation from KKNPP Units 1 & 2

Future Expansion: Units 3 to 6
Four new reactors—KKNPP Units 3, 4, 5, and 6 (each 1000 MW)—are currently under construction. Once operational, they will increase the site’s total capacity to 6000 MW, further strengthening India’s clean energy infrastructure.
Decisions regarding power allocation from these upcoming units will be taken by the Ministry of Power at an appropriate time.
The Kudankulam project, a joint venture between India and Russia, represents a major step in India’s pursuit of nuclear energy as a clean and reliable power source, contributing to the country’s energy security and climate goals.
