Hydro power production can be modelled at reservoirs and run-of-river hydro power stations. The produced energy is computed based on the hydro-power station characteristics and the actual water levels upstream (reservoir water level) and downstream (tail water level).

Firm energy production forms one of the water using activities in the basin and is fully taken into account in the water management options.
