The main objective of the CBA methodology is to provide a common and uniform basis for the assessment of projects with regard to their value for European society. It provides important input for the selection of European Projects of Common Interest.

Following the revised TEN-E Regulation (EU) 2022/869, including the requirements for the content of the methodology for the system-wide CBA, ENTSO-E’s 3rd CBA Guideline* has been updated to a fourth version to comply with the new requirements.

The 4th CBA Guideline aims at providing guidance on how to perform an energy system-wide cost-benefit analysis. The Guideline describes ENTSO-E’s criteria for performing cost benefit analysis along with the common principles and methodologies to be used in the necessary network studies, market analyses, and interlinked modelling methodologies.
