PUMPED STORAGE HYDROELECTRIC SCHEMES AND WATER

Once the water has run through the turbines it is discharged back into the river below the power station to continue its course. Because it is necessary to pump the water back after use, pumped storage power stations can only provide energy for limited periods of time. In addition they are more expensive to operate than conventional

Pumped Storage Plant

Thus, pumped storage plants can operate only if these plants are interconnected in a large grid. Principle of Operation. The pumped storage plant is consists of two ponds, one at a high level and other at a low level with powerhouse near the low-level pond. The two ponds are connected through a penstock. The pumped storage plant is shown in fig. 1.

Pumped hydro storage for intermittent renewable energy

Globally, communities are converting to renewable energy because of the negative effects of fossil fuels. In 2020, renewable energy sources provided about 29% of the world''s primary energy. However, the intermittent nature of renewable power, calls for substantial energy storage. Pumped storage hydropower is the most dependable and widely used option
