This paper presents the outcome of the cost-benefit analysis (CBA) for the different alternatives defined in the project SmartNet for the coordination between transmission system operators (TSOs) and distribution system operators (DSOs). The CBA compares five coordination schemes in three countries (Italy, Denmark and Spain) on the basis of several economic indicators. On top of them, it also calculates some non-economic indicators to enrich the analysis. The main results for the Italian and the Spanish cases are presented in this paper.The research leading to this article has received funding from the European Union’s Horizon 2020 research and innovation programme under grant agreement No 691405
