Consider the following statements regarding pumped storage plants:1.A pumped storage plant is a base load plant.2.The starting time of a pumped storage plant is very short.3.Reversible turbines and pumps are highly suitable for pumped storage plants.Which of these statements are correct?

Correct Answer: B - 2 and 3 only

Quick Concept Explanation

Pumped-storage hydro stores energy by pumping water to an upper reservoir during low-demand periods and generating during peaks. Its rapid start and reversible pump-turbine equipment make it valuable for peak support, balancing and reserves rather than as a conventional base-load plant. Key relation: Stored potential energy≈ρgH·volume.

Exam focus: Pumped storage shifts energy in time; it does not create net energy. Common trap: Do not classify it as a normal base-load plant.

Statement-wise Verification

• Statement 1 - Incorrect.
  A pumped storage plant is a base load plant.
  Pumped storage is typically used for peak support, balancing and storage rather than continuous base load
• Statement 2 - Correct.
  The starting time of a pumped storage plant is very short.
  Pumped storage shifts energy in time; it does not create net energy.
• Statement 3 - Correct.
  Reversible turbines and pumps are highly suitable for pumped storage plants.
  Pumped storage shifts energy in time; it does not create net energy.

Core Concept

Pumped-storage hydro stores energy by pumping water to an upper reservoir during low-demand periods and generating during peaks. Its rapid start and reversible pump-turbine equipment make it valuable for peak support, balancing and reserves rather than as a conventional base-load plant.

Formula / Key Relationship

Stored potential energy≈ρgH·volume.

Why the Other Options Are Wrong

Option A is incorrect because it includes incorrect statement(s) 1 and omits correct statement(s) 3. Option C is incorrect because it includes incorrect statement(s) 1 and omits correct statement(s) 2. Option D is incorrect because it includes incorrect statement(s) 1.

Exam Shortcut / Approach

Pumped storage shifts energy in time; it does not create net energy.

Common Mistake

Do not classify it as a normal base-load plant.

Quick Revision

Pumped Storage Operation is linked with Pumped Storage, Power Plants and Power Systems. Pumped storage shifts energy in time; it does not create net energy.
