11.8.2. RUN-OF-RIVER POWER PLANTS
These plants can be classified as either without pondage or with pondage. A run-of-river plant
without pondage has no control over river flow and uses the water as it comes. These plants usually
supply peak load. During floods, the tail water level may become excessive rendering the plant inopera-tive. A run-of-river plant with pondage may supply base load or peak load power. At times of high water
flow it may be base loaded and during dry seasons it may be peak loaded.
