Q. Consider the following regarding the challenges faced by the Indian power sector:

1. Low energy efficiency
2. High load factor
3. Low utilization factor
4. High Aggregate Technical and Commercial (AC & T) losses

Which of the above are significant challenges in India's power industry?
Answer: Only 1, 3 and 4
Notes: Major challenges in India's power sector include low energy efficiency, low utilization factor due to irregular fuel supply, and high technical and commercial (AT&C) losses (about 32%). High load factor is not a challenge; low load factor is. Over 65% of installed capacity is thermal, often operating below potential. Thus, statements 1, 3, and 4 are correct.
