UPSC Prelims 2008 Q53: Indian Economy – Infrastructure & Industry
Which of the following pairs in respect of current power generation in India is/are correctly
matched? (Rounded Figure)
1. Installed electricity generation capacity : 100000 MW
2. Electricity generation : 660 billion kWh
Select the correct answer
using the code given below:
- (a) 1 only
- (b) 2 only
- (c) Both 1 and 2
- (d) Neither 1 nor 2
Answer: (b) 2 only
Explanation
Checking two figures on India's power generation
These statements test specific rounded figures for India's electricity generation capacity and output around this period.
| Statement | Verdict | Reason |
|---|---|---|
| 1. Installed electricity generation capacity: 100,000 MW | Incorrect | India's actual installed capacity at the time was higher than 100,000 MW, making this figure an understatement |
| 2. Electricity generation: 660 billion kWh | Correct | This figure is roughly consistent with India's actual electricity generation around this period |
Correcting the capacity figure:
| Point | Detail |
|---|---|
| Installed capacity (actual) | Higher than the stated 100,000 MW |
| Electricity generation | ~660 billion kWh — accurate |
Answer: (b) 2 only.
Why each option is right or wrong
- (a) Incorrect. The installed capacity figure understates the actual figure, so '1 only' is wrong.
- (b) CORRECT. The generation figure (660 billion kWh) is roughly accurate; the capacity figure is understated.
- (c) Incorrect. Statement 1 is inaccurate, so 'both' cannot be correct.
- (d) Incorrect. Statement 2 is accurate, so 'neither' is wrong.
Key point
India's electricity generation figure of ~660 billion kWh checks out — but the installed capacity figure of 100,000 MW understates the actual installed capacity at the time.
Remember
India's electricity generation (~660 billion kWh) checks out; the installed capacity figure of 100,000 MW understates the actual figure.
Common mistakes
- Accepting a rounded capacity figure without comparing it to the actual contemporary installed capacity.
- Confusing installed capacity (MW, a power rating) with generation (kWh, an energy output over time).
- Assuming both statistical claims in a question must be either both true or both false.
Exam tip
Installed capacity (MW) and generation (kWh) are different metrics — always verify each numeric claim against the actual contemporary figures separately.
