Sustainable Hydropower & Non-chemical Water Treatment

How Run-of-the-River Power Plants Work?

A Run-of-the-River Hydroelectric power station generates electricity from a flowing river. This type of power station belongs to the renewable energy group and has an operating efficiency far higher than other renewables such as wind and solar power. Run-of-the-river power stations utilize Kaplan or Francis turbines.

Water from the river is diverted by a dike to the power station penstock. The water then passes through a turbine runner and the runner begins to rotate. A generator is connected to the runner on a common shaft and electricity is generated as the generator rotor rotates within the stator.

Electricity is then fed through switchgear to an electrical transformer where the voltage is increased. Increasing the voltage reduces electrical losses that would be incurred during transmission and also allows the distribution cables to have a smaller diameter. After the transformer, the current is fed to the open-air switchyard and into the national grid.

Hydropower modernization

We develop a new hydropower design based on a "Run-of-River" - diversion concept, as it does not require the use of a dam. Our priority is to let rivers flow at their natural rate to preserve the ecosystem and its biodiversity for long-term sustainable hydropower.

A diversion facility channels a portion of a river through a canal and/or a penstock to utilize the natural decline of the river bed elevation to produce energy. A penstock is a closed conduit that channels the flow of water to turbines with water flow regulated by gates, valves, and turbines.
