How does pumped storage hydropower technology contribute to the stability of the power grid?

• It helps to balance supply and demand by storing and releasing excess energy.

• It has no impact on the stability of the power grid.

• It contributes to air pollution by releasing excess energy into the atmosphere.

• It causes fluctuations in energy supply by storing and releasing excess energy.

Explain the concept of peak shaving in the context of pumped storage hydropower technology.

• Pumped storage hydropower technology is not related to managing peak electricity demand

• Pumped storage hydropower technology is used to store excess electricity during off-peak hours

• Peak shaving in pumped storage hydropower technology refers to reducing the efficiency of electricity generation

• Pumped storage hydropower technology helps to shave off peak electricity demand by releasing water from the upper reservoir to the lower reservoir and generating electricity during periods of high demand.
