Hydropower: Turbine Power | Energy Reservoir Power Station

Reservoir Power Station Energy Calculator

Calculates the energy of a reservoir power station from height and volume. A reservoir power station produces energy from water flowing down from a reservoir above. If the water also can be pumped up, it is a pumped storage power station.
The formula for the energy calculation is E = η * ρ * g * h * V, almost the same as for hydropower. At a reservoir power station, the calculation is done with volume, not with volumetric flow, so the energy produced by an amount of water is calculated, not the power.
Please enter height and volume to calculate the hereby produced energy.

Example: a modern reservoir power station with an efficiency factor of 85% has a potential energy height of 100 meters. If 10000 cubic meters of water flow down, about 2.3 megawatt-hours of electricity are produced.

A reservoir power station of the company Bosch in Blaichach, Bavaria (Germany).

Storage power plants store potential energy in a reservoir in the form of water that has been raised to a height. If the water is drained through the outlet, it flows downwards. At the lower end it drives turbines that convert the kinetic energy of the flowing water into electrical power. This is a reliable technology that has been tried and tested for a long time and is usually very efficient. This technology is also an important part for the energy transition, in order to store electricity when a lot is being produced and to access the electricity again when production is low. The disadvantages are the large space requirement and the environmental impact required for construction. Only areas with a relevant difference in altitude are suitable for construction; such storage power plants cannot be built in lowlands.
