Where are Tapovan and Vishnugad Hydroelectric Project located?

Answer: (c) Uttarakhand

Tapovan–Vishnugad (520 MW) is on the Dhauliganga in Chamoli, Uttarakhand.

The idea

A hydropower project is tied to a specific river valley and State. Its town names are stronger location clues than a broad “Himalayan power” association. Uttarakhand had already separated from Uttar Pradesh by the 2008 exam year.

Elimination technique

The Chamoli–Joshimath valley is in Uttarakhand. Apply the post-2000 State boundary rather than the older Uttar Pradesh label to resolve the location options.

Also know

The Dhauliganga of the Alaknanda basin meets Alaknanda at Vishnuprayag near Joshimath. A different Dhauliganga drains towards the Kali in eastern Uttarakhand; the names must not be confused. Tehri is on Bhagirathi, while Vishnuprayag is an Alaknanda project. River and project names can share a confluence label without being identical sites.
