What This Article Covers

1.Project cost of KKNP Units 3-6 increased from ₹89,470 crore to ₹1,38,330 crore (55% rise) since Russia-Ukraine war.

2.Units 3&4 cost rose 72.9%, Units 5&6 by 39.9% over their respective sanctioned costs.

3.Similar cost escalations at Kaiga, Gorakhpur, and Rajasthan projects threaten competitiveness of nuclear power in India's price-sensitive market.

The Big Picture
Prelims · HighMains · High

Cost of four under-construction nuclear reactors at Kudankulam has risen by 55% to ₹1,38,330 crore, driven by Russia-Ukraine war. This poses a challenge to India's ambitious nuclear expansion plans and could increase electricity tariffs, especially as the government opens the sector to private participation.
