Optimal use of hydropower plants depends on detailed knowledge of water resources. Based on quantitative forecasts for precipitation and temperature, Powel Inflow is well suited to predict inflow. This information makes it possible to improve reservoir usage and thus allows for a more efficient and profitable operation of the hydropower
system. Correct reservoir usage is vital for hydropower plants with low regulation capacity, when water level in the reservoir reaches highest or lowest regulated water level. Powel Inflow is also well suited in situations where the desire to increase net head must be balanced against the risk of increased spillage or flood.
