Question

In which Indian state is Asia's first underground hydroelectric project located?

Hint:

Look for a hilly northern state known for steep rivers and hydroelectric projects built inside the mountain.

Answer 1

The answer is Himachal Pradesh.

1. Himachal Pradesh lies in the Himalayan belt, with rivers that drop steeply and carry strong water flow.
2. Engineers placed the turbines and generators inside rock caverns below the surface instead of building an open power house.
3. This was a new method in Asia at the time, so the project earned the title of the first underground hydroelectric station on the continent.
4. The underground design also keeps the machines safe from heavy snow and landslides that affect hill states.

This is why Himachal Pradesh is linked with this achievement in general knowledge questions.
