MH SET - 2025, SET Exam - 2025,
Answer: A
The criterion that is not primary is altitude.
What a hydroelectric site needs is a reliable flow of water and a usable head, the difference in level between the reservoir and the turbines. The absolute altitude of the site above sea level does not matter; a low-lying site with a large drop between the dam and the powerhouse can be excellent.
The other options are primary site criteria. Water availability decides how much energy can be generated through the year. A large catchment area feeds that water into the reservoir. Rocky land, meaning sound rock foundations, is needed to support the dam and resist seepage.
