Former Associations

ENTSO-E is proud to continue the long history of successful TSO coordination work by 6 predecessor associations. The different committees, working groups and, task forces have transferred their work into the current ENTSO-E structure where the well-established work will continue, and also be enhanced through ENTSO-E's pan-European perspective.

The data and documents of the ENTSO-E predecessor associations have been integrated into the ENTSO-E website. Below we list the main resources of their websites and where to find them on the ENTSO-E Website.
