Planning task D: Impact estimation

The goal in the previous C-tasks was to identify the possible alternatives to the planning problem and the most relevant criteria to compare among these alternatives. We saw that criteria have to be assigned with measurement scales in order to make the comparison among the alternatives possible.

This planning task focuses on the estimation of how alternatives analysed perform in respect to the different planning criteria. Impact estimation provides thus the means for comparison of alternatives. The impacts are not absolute figures – these are figures calculated based on the information available in planning, and considering all identified uncertainties. Often, additional information about alternatives considered might shed new light into the impacts that specific alternative have in some criteria, and this implicitly may change the rank of this alternative on the chosen measurement scales. 

Different tools might be used for the calculation of various impacts. For instance, economic impacts (costs, profits, etc.) can be calculated using economic models; technical indicators can be calculated using computer based energy system simulation models, while environmental indicators can be calculated using environmental models.

Information about different tools that can be used can be found in the menu above. Also, by browsing through the case-studies you can find examples illustrating how key performance indicators are calculated and used.
