India's Nuclear Power Corporation of India Ltd (NPCIL) has successfully synchronised a 700 MW unit at its Rajasthan Atomic Power Project (RAPP) in Rajasthan (north-western India) with India’s Northern Grid. After complying with all pre-requisites including those stipulated by Atomic Energy Regulatory Board (AERB), the RAPP-7 reached first criticality in September 2024 and it will continue to ramp up its power level in steps to full power, in line with the regulatory clearances.
The unit constitutes the third reactor of 700 MW series of sixteen indigenous Pressurised Heavy Water Reactors (PHWR) being set up in India, which could generate about 5.2 GWh/year of clean electricity (at 85% Plant Load Factor) thereby averting about 4.5 MtCO2e emissions annually. Its twin unit, the RAPP-8 is expected to be operational in 2025-2026.
The Rajasthan Atomic Power Project already has six units with a total capacity of 1180 MW, with the RAPP-7 and the eventual addition of the RAPP-8, the power plant should increase its total installed capacity to 2,580 MW
NPCIL operates 25 reactors with a total capacity of 8,880 MW. In addition, the company has over 13 GW under development to be launched by NPCIL in the future to contribute about half of India’s 100 GW nuclear power capacity by 2047 target.
