A run-of-river power plant is used on rivers with a very small fall in elevation and a high flow rate of water. The turbines operate nonstop, meaning they can produce electric power continuously and have very low operating costs. The river water flows through a turbine, which drives a generator, thus producing electricity. An effective head of a few meters is sufficient for run-of-river power plants, but the pressure difference is low. That’s why Kaplan turbines are often used as tubular turbines (horizontal installation) in these cases. They sometimes also have high-speed gearboxes (pit turbines).
