Projects of Common Interest (PCIs) are key energy infrastructure projects, which will help EU members to integrate their energy markets and, in particular, end the isolation of some Member States from Europe-wide energy networks. Projects of Common Interest are of particular importance for Europe's energy system due to the multiple benefits that they provide. In this paper, it is presented an assessment methodology for PCI candidate project proposals, with an example of how a PCI is selected.

... Cost Benefit Analysis for transmission projects There are two ways for the project assessment that can be adopted: • Take Out One at the Time method, consisting in excluding one-by-one the grid elements and evaluate the load flows over the lines with and without the examined network project; • Put IN one at the Time method, that considers each new item grid element on the given network structure one-by-one and evaluates the network flows over the lines with and without the examined network project. The first method provides an estimation of benefits for each project, as if it was the last to be commissioned. In fact, the first method evaluates each new development investment/project into the whole forecasted network. The advantage of this analysis is that it immediately appreciates every benefit brought by each investment, without considering the order of investments.
