The main types of hydropower systems are:
1. Run-of-the-River (diversion)

b. Typically installed for small hydropower systems.
c. Flowing water is channelled from the river through a canal or penstock to spin a
turbine to produce electricity.
2. Impoundment (Reservoir/dams)
a. These systems use a dam to store water in a reservoir.
b. Typically installed for large hydropower systems.
c. Water is released from the reservoir through the penstock to spin a turbine
which activates a generator to produce electricity.
