Run-of-river power plants
These are located on the banks of rivers and use the water’s energy to produce electricity. The water returns to the river downstream of the plant.
The power plant is referred to as High Head when the water is delivered from a high level to a power plant located several dozens of metres lower down via a penstock.
These power plants are present where the flow of water is slow and there is a significant difference in height.
Conversely, low head power plants are characterised by a strong water flow and a relatively small height difference.
