The main elements of the PSAs are:
- The affirmation of an advantageous regulatory transit regime under European Union and Turkish energy law;
- The protection of the Nabucco Pipeline from potential discriminatory changes in the law; and,
- Support for legislative and administrative actions for the further implementation of the project.
The PSAs also mark a commitment by each government to support the project. Together with the Intergovernmental Agreement, the PSAs are a necessary prerequisite for the successful financing of the project.
