A.Gujarat
B.Maharashtra
C.Karnataka
D.Tamil Nadu

Answer 1

Hint: Hydroelectric power is electrical energy that is produced by the power of moving water or power that is acquired through the movement of water. Hydroelectric power plants draw energy from the forces that move water and use this energy for useful purposes.

Complete answer: Option A: Kadana Dam is a dam on the Mahi River in Mahisagar district of Gujarat, India. The dam which was constructed between 1979 and 1990 is also a pumped-storage hydroelectric power-station. The first two generators were commissioned in 1990 and the second two were commissioned in 1998. The dam is 66 m in height and the capacity of the hydro plant is 240 MW.
Option B: The Koina Hydropower Project is India's largest completed hydropower plant. It is a multifaceted project with four dams as well as the largest dam on the Koyna River, Maharashtra hence its name Koyna Hydroelectric Project. The project site is in the Satara district with a total capacity of 1960 mw.
Option C: Karnataka Power Corporation Limited (or KPCL) is a state-owned Karnataka government- company that oversees power generation, and KPCL has 34 dams and 24 power plants across the state with power generation capacity from 0.35 MW to 1035 MW.
Option D: The Tamil Nadu Generation and Distribution Corporation Limited is a company that oversees the generation and distribution of power in the state of Tamil Nadu.

Therefore the correct answer is Option B Maharashtra.

Note: The most common method of generating hydropower is by establishing hydroelectric dams. Usually, a dam is built to block river water and to create a large reservoir of water. The water from the reservoir is allowed to flow over the dam in such a way that the water falls on turbines and the turbines turn, generating electricity.
