In 2009 a new price system for the produced power was introduced for Norwegian hydro power plants. 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 HydroPlant Libra of Modelon AB. The model was parametrised using construction data and validated usindata from test and operation runs.
