Reservoir Power Station Energy Calculator

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.
