Energy storage, particularly pumped-hydro storage, is incredibly important for grid integration because it provides flexibility and stability. It allows hydropower to act as a large-scale battery, absorbing excess energy during low demand and releasing it during peak demand, thereby balancing intermittent renewable sources like solar and wind.

Question 13

What is cavitation, and how do you prevent it in turbines?
Answer:
Cavitation is the formation and collapse of vapor bubbles in a fluid, typically occurring at low-pressure points within a turbine. It causes pitting and erosion, reducing efficiency and lifespan. Prevention methods include careful turbine design, selecting appropriate operating ranges, maintaining adequate submergence, and ensuring proper water flow conditions.

Question 14

How do you approach risk management in hydropower projects?
Answer:
My approach to risk management involves identifying potential risks early in the project lifecycle, such as hydrological uncertainties, geological surprises, or regulatory changes. I then assess their likelihood and impact, develop mitigation strategies, and establish contingency plans. Regular risk reviews are also crucial to adapt to evolving conditions.

Question 15

Describe your experience with project scheduling and budgeting.
Answer:
I have managed project schedules using tools like Primavera P6 and Microsoft Project, ensuring tasks are logically sequenced and milestones are met.

Answer:
Environmental flow refers to the quantity, timing, and quality of water flows required to sustain freshwater and estuarine ecosystems and the human livelihoods and well-being that depend on these ecosystems. It’s crucial for maintaining biodiversity, supporting fish populations, and ensuring ecological health downstream of hydropower facilities.

Question 19

Can you explain the concept of pumped-hydro energy storage?
Answer:
Pumped-hydro energy storage uses two reservoirs at different elevations. During periods of low electricity demand, excess grid power is used to pump water from the lower to the upper reservoir. When demand is high, water is released back to the lower reservoir, flowing through turbines to generate electricity, effectively storing and releasing energy.

Question 20

Where do you see the future of hydropower in the broader energy landscape?
Answer:
I see hydropower continuing to be a cornerstone of the global energy mix, particularly as a flexible and reliable baseload power source that can also integrate with intermittent renewables.
