What are Run-of-River Hydro Projects?
- Run-of-river hydro projects use the natural downward flow of rivers and micro turbine generators to capture the kinetic energy carried by water.
- Typically, at a high point along the river a dam is constructed to create a headpond in front of the dam.
- From the dam water is diverted from the river through a pipeline ('penstock') which leads to a downstream powerhouse.
- The water level in the headpond is to ensure that the intake to the penstock remains under water.
