Developing new networks in Europe in order to facilitate cross-border flows requires a close coordination of several processes and actors.
A common EU-wide Cost-Benefit Analysis methodology was developed by ENTSO-E to be used for infrastructure projects assessment, and it is reviewed when needed.
Every two years, based on the scenarios on the future state of the electrical system, ENTSO-E assesses the projects included in the EU-wide Ten-Year Network Development Plan (TYNDP).
