The content of this paper is a compilation of the results and findings of several working groups comprising business and legal experts of IMs/ABs/C-OSSs and applicants. The new process described (TTR) introduces a new approach to capacity management. Existing process components have been streamlined and improved, and some innovative process components and products newly created to fully cover all market requirements.

The document consists of the following content:

  • Main document
  • Annex 1 "Process description of long-term & advanced planning"
  • Annex 1.1 Example of a capacity model on a defined line with details
  • Annex 1.2 “Capacity announcement management”
  • Annex 2 "minor/major changes to the path request/applicant’s modification to the allocated path" (to be published soon)
  • Annex 3 "Leading entity" 
  • Annex 4 "Process diagrams"
  • Annex 5 "Practice-related use cases"
  • Annex 6 "Use cases related to path modifications" 
  • Annex 7 “Allocation guidelines for conflicting capacity announcements and requests”


Please, note that the TTR process description is a working document and is expected to be subject to changes based on the experience gathered through the pilots and outputs of the TTR working groups.
