Run-of-River Hydropower Flows

A run-of-river hydropower facility (ROR) generates hydropower from a fixed head on the river (see Hydropower Calculations for details). It does not have any storage nor does it remove water from the river. The flow out of the facility equals the flow in from upstream, plus demand site (DS) and treatment plant (TP) return flows that come in at that point. (See Hydropower Calculations for details of hydropower generation.)
