The following page lists hydroelectric power stations that generate power using the run-of-the-river method. This list includes most power stations that are larger than 100 MW in maximum net capacity, which are currently operational or under construction. Those power stations that are smaller than 100 MW, and those that are only at a planning/proposal stage, may be found in regional lists, are listed at the end of the page.
Run-of-the-river hydroelectricity
Run-of-river hydroelectricity (ROR) or run-of-the-river hydroelectricity is a type of hydroelectric generation plant whereby little or no water storage is provided. Run-of-the-river power plants may have no water storage at all or a limited amount of storage, in which case the storage reservoir is referred to as pondage. A plant without pondage is subject to seasonal river flows, thus the plant will operate as an intermittent energy source. Conventional hydro uses reservoirs, which regulate water for flood control, dispatchable electrical power, and the provision of fresh water for agriculture.
