The first two 1,000 MW VVER reactors of the Kudankulam Nuclear Power Project (KKNPP), built with Russian technical knowledge, have generated over 1.22 lakh million units of electricity till December 2025. Besides, the KKNPP administration has achieved 83% physical progress in the ongoing construction of the third and fourth reactors coming-up on India’s largest ‘Nuclear Park’ in the district.
Delivering the Republic Day address at Anu Vijay Township, the residential colony of the KKNPP officials in Chettikulam on Monday, Site Director of KKNPP B. Sathish Kumar said the plant’s Unit-1, commissioned in October 2013, had generated 68,156 million units of power, and Unit-2, after being commissioned in October 2016, had produced 54,080 million units of clean energy during the period between the first synchronization and December 2025.
Hence, the total quantum of power generated by both reactors has crossed 1,22,236 million units till December 2025, indirectly preventing the release of around 106 million tonnes of carbon dioxide into the atmosphere, he said.
Mr. Sathish Kumar contended, “With excellent operational capacity, KKNPP’s reactors one and two will achieve record generation and capacity factor during the financial year of 2025-26.”

SPECIAL ARRANGEMENT
Regarding the construction of reactors three and four, which were being built at an outlay of ₹39,849 crore, he said work was in full swing. The overall physical progress was 83% as of December 2025, with the completion of major milestone achievements such as commencement of pre-stressing activities in Unit-3, inner containment dome concreting in Unit-4, turbine generator, including condenser erection completion, in Unit-3, commissioning and charging of a 220-KV gas insulated substation and extending power supply, commissioning of the desalination and demineralizing plants, and transfer of demineralised water to Unit-3 for taking up process system commissioning.
Mr. Sathish Kumar said KKNPP reactors five and six, which would be built at a cost of ₹49,621 crore, had achieved physical progress of 41%, with civil works of all major structures such as reactors, turbines, and safety buildings progressing well. A package contract for mechanical and instrumentation work has been awarded.
“All these could be achieved by the dedicated contribution of the strong KKNPP team, with the support of the headquarters team, Russian specialists, our contractor partners, and family members of the KKNPP team,” the Site Director said.
Mr. Sathish Kumar said KKNPP was very keen on the development of its neighbourhood and an amount of ₹132 crore had been spent so far for infrastructure developments in education, medical, water supply, clean energy, and various other public utilities under its Corporate Social Responsibility (CSR) programme for the benefit of the local residents.
“Nuclear energy is a symbol of progress, innovation, and sustainability. It represents our commitment to providing clean, reliable, and affordable energy to the nation while addressing the pressing challenges of climate change and energy security. Over the years, our dedicated team has demonstrated exemplary commitment to excellence, ensuring the safe, reliable, and efficient operation of this facility,” Mr. Sathish Kumar said.
