Types of Hydropower

Figure 1: Hydropower plant with main components ‍ Hydropower systems. There are four main types of hydropower projects. These technologies can often overlap. For example, storage projects can often involve an element of pumping to supplement the water that flows into the reservoir naturally, and run-of-river projects may provide some storage

Pumped Storage Power Station (Francis Turbine)

During the day, power is in demand and electricity prices are high. At night, power is not in demand and electricity prices are low. Pumped storage power plants purchase power at night to pump water up to the upper reservoir, they then generate power and sell it back to the grid during the day, when the demand -and price- is higher. Example 1

Pumped Storage Hydropower: Advantages and Disadvantages

Releasing water from the upper reservoir through turbines generates power. This process is crucial during peak electricity demand periods. Design Efficiency: The design of dams in pumped storage systems is tailored to maximise energy storage and generation efficiency. This involves considerations of dam height, water flow, and storage capacity.
