UPSC asked three “none of them” claims about India’s coal power plants. All three turned out to be false.
🏛️ Must Know
Three “None of Them” Claims, All Wrong
- Some Plants Do Use Seawater Some coal-based thermal power plants in India genuinely use seawater for cooling. The Tata Mundra Ultra Mega Power Project in Gujarat is one example.
- Many Sit in Water-Stressed Districts Roughly 40% of India’s thermal power plants are located in regions facing significant water stress.
- Many Are Privately Owned India’s roughly 269 thermal power plants split nearly evenly. Around 131 are owned by the private sector and 138 by the public sector.

Why Water Access Is a Real Constraint
- Cooling Needs Huge Water Volumes Coal thermal plants need enormous volumes of water for steam generation and cooling. This makes water access a genuine operational risk.
- Coastal Plants Turn to Seawater Coastal plants like Tata Mundra use seawater specifically to reduce pressure on scarce freshwater sources nearby.
- A WRI-Documented Risk Research by the World Resources Institute has documented how many Indian thermal plants sit in water-stressed regions.

UPSC CSP 2023 — None of These “None of Them” Claims Hold Up
- UPSC 2023 All three “none of them” statements are actually false. Some plants use seawater, many sit in water-stressed districts, and many are privately owned. See UPSC CSP 2023 GS Paper I, Q66. View this question.

Why This Question Style Is Tricky
- Triple-Negative Statements Statements phrased as “none of them” are easy to misjudge. A reader must know a real counterexample exists for each one.
- A Genuine Water-Energy Tradeoff India’s coal fleet illustrates a real tension between energy demand and water security, a recurring UPSC theme.
- Connects to Other PYQ Facts This same water-stress angle also comes up in UPSC questions on India’s groundwater withdrawal and irrigation dependence.
