A-priori estimation of the impact of measures in power generation, e.g. by using simple rules of thumb, can lead to erroneous conclusions because an interconnected power system is too complex to seize in an "average" system. The new boundary conditions (such as the liberalisation of the power markets and greenhouse-gas emission reduction targets) even add to the complexity of the context. Therefore, this paper discusses a simulation strategy for the correct qualification and quantification of power generation in a set of interconnected zones. As an example of this approach, this paper discusses two hypothetical case studies for power generation in eight interconnected EU countries. Starting from a standard test case, two variations are simulated. The first example studies the impact of the cross-border trade limitation imposed by the limits of the transmission lines between zones. The second example studies the effect of a CO2 tax. Both examples demonstrate that it is not straightforward to a-priori predict all separate effects and the interaction between them.
