Product Details

Units and Power Estimations

Power: watts [W] or Kilowatts [kW] 1 kW = 1000W
Flow: 1 m³/s = 1000 l/s
Gross heat: height difference the water "falls down"
Net head: a little smaller than gross head. Gross head deducted by energy loss due to friction in penstock


Potential power ('electric)' is calculated as follows:
Power [W] = Net head [m] x Flow [ l/s] x 9.81 [m/s²] (est. gravity constant) x 0.8(turbine/generator efficiency)
Potential power is estimated as follows:
Power output [W] = height [m] * flow [l/s] * 8


More accurate estimations take into consideration:

●  exact net head (intake to powerhouse)

●  exact flow (constant during the years)

●  combined efficiency of turbine and generator (depends on quality, est. 60% = 0.6)


Hydropower plants can be classified in three categories according to operation and type of flow:

1.      Run-of-river (RoR), 
Small and micro hydropower utilizes water that runs of a river and avoids big environmental impacts.

2.      Storage (reservoir)

3.      Pumped storage hydro power plants (HPPs) work as energy buffer and do not produce net energy.

4.      In-stream Hydropower Schemes use a rivers natural elevation drop without to dam a river.


●    RoR plant produce energy from the available flow and the natural elevation drop of a river

●    It is suitable for rivers that have at least a minimum flow all year round.

●    The water to powers the turbine is diverted and channeled into a penstock and then returned to the river

●    RoR plants usually have no or only small storage, allowing for some adaptations to the demand profile.

●    As bigger the storage capacity is as higher the environmental impacts are

●    Power generation is dictated by local river flow conditions and thus depends on precipitation and runoff and may have substantial daily, monthly or seasonal variations


●   Hydropower projects with a reservoir (storage hydropower) store water behind a dam for times when river flow is low

●   Therefore power generation is more stable and less variable than for RoR plants

●   The generating stations are located at the dam toe or further downstream, connected to the reservoir through tunnels or pipelines

●   Type and design of reservoirs are decided by the landscape and in many parts of the world are inundated river valleys where the reservoir is an artificial lake

●   Reservoir hydropower plants can have major environmental and social impacts due to the flooding of land for the reservoir


●    Pumped storage plants are not energy sources, instead they are storage devices

●   Water is pumped from a lower reservoir into an upper reservoir, usually during off-peak hours, while flow is reversed to generate electricity during the daily peak load period or at other times of need

●    Although the losses of the pumping process make such a plant a net energy consumer, the plant provides large-scale energy storage system benefits

●   Pumped storage is the largest capacity form of grid energy storage now readily available worldwide
