Basically a power producer gets punished if his production deviates from the scheduled production. The power plant is paid for the actual production: if too much power is produced that the price for the excess power is low. Even worse if too little power is produced the power plant has to pay a fine. If such deviation occurs it is very important to identify components/systems that are responsible in order to adjust the controller or replace the faulty equipment. This paper describes the first step in problem solving, by presenting the development of a model of a hydro power plant that shows differing power production. The modelling part was done in Modelica using the HydroPlant Library1 of Modelon AB. The model was parametrised using construction data and validated using data from test and operation runs. ## Site Description Modelon is revolutionizing the engineering design industry by offering technologies and services that enable customers to leverage system simulation.
