Q. Consider the following statements:
1.Pumped Storage Hydropower (PSH) can store excess energy generated during peak production times and release it when needed.
2.At present, India does not have installed pumped storage capacity.
3.PSH can operate independently of the grid.
How many of the statements given above are correct?
Answer: A
Notes:
Explanation –
Statement 1 is correct. Pumped Storage Hydropower (PSH) works by pumping water to a higher elevation during times of excess energy production and releasing it to generate electricity when needed, effectively storing and releasing energy as required.
Statements 2 and 3 are incorrect. India has installed pumped storage capacity. For example, the Tehri Dam in Uttarakhand includes a pumped storage component, and there are other such facilities in the country. PSH systems are typically integrated with the grid. They store energy when there is excess generation and release it during periods of high demand, thus supporting grid stability and reliability.
