Q. With reference to the Lower Subansiri Hydroelectric Project (LSHP), consider the following statements:

1. It is a storage-based hydropower project located entirely within Arunachal Pradesh.
2. The LSHP is being developed by the National Hydro Power Corporation (NHPC).
3. The Subansiri River, on which LSHP is being constructed, is a tributary of the Brahmaputra.
4. The project involves installation of Pelton turbines due to high head requirements.

Which of the above statements is/are correct?
Answer: 2 and 3 only
Notes: Statement 1 is incorrect as LSHP is a run-of-the-river project and is located on the border of Arunachal Pradesh and Assam, not entirely within Arunachal Pradesh. Also, Statement 4 is incorrect as the project uses Francis turbines, not Pelton turbines. Francis turbines are suitable for medium-head conditions, therefore option B (2 and 3 only) is the correct answer.
