Hydropower without dams
WebHydropower plants based on water flow. Storage hydropower plants: This is the most widespread system. By building one or more dams, reservoirs are formed that store large amounts of water and, in this way, regulate the flow that passes through the turbines to generate electricity. This means energy production can be stable throughout the year. WebHydropower without dams and reservoirs means producing at a smaller scale, typically from a facility designed to operate in a river without interfering in its flow. For this reason, many consider small-scale hydro a more environmentally-friendly option.
