A method for controlling a power assembly comprising a fuel cell unit and an electric energy storage system for storing excess electric energy produced by the fuel cell unit. The method comprises predicting a power demand from the power assembly over a prediction time horizon, obtaining a state-of-charge and/or power capability of the electric energy storage system, based on the predicted power demand and the obtained SoC and/or power capability, identifying a time period during which the power assembly is expected to be able to deliver power in accordance with the predicted power demand with the fuel cell unit shut down, or is at least expected to be able to deliver power at a minimum power level determined with respect to the predicted power demand, controlling the power assembly to shut down the fuel cell unit during at least a part of the identified time period in response to the identified time period being larger than a time threshold.
