According to the TEN-E Regulation all PCI candidates have to be included in the TYNDP, starting with this edition. Some projects were not in a position to provide the data necessary to be fully assessed through a CBA following ENTSOG methodology. These projects are never- theless listed within Annex A of this Report, to ensure that they fulfil the minimum requirement of the TEN-E Regulation. To build a bridge between two sequential PCI selection rounds, ENTSOG has intro- duced the PCI Infrastructure scenario 1) . This additional scenario enables the assessment of the cumulative effects of the previous PCIs including their interaction. In line with the TEN-E Regulation ENTSOG has provided a common basis for the Project-Specific CBA of each PCI candidate (see Annex F). This involves the assessment of different development levels of the gas infrastructure based on the FID and PCI status of the projects. TYNDP will be used by the Regional Groups as a background when considering the Project Specific CBAs of the candidate projects.
2.5 Analysis of project submission
The full detail of the 259 projects submitted for inclu- sion in the TYNDP 2015 can be found in Annex A of this Report, which also provides enhanced search and sort- ing functionalities on all projects. This section of the report provides a general overview of the submitted projects. Projects are classified according to the five types of infrastructures as follows: \\ TRA Transmission, incl. Compressor Stations \\ LNG LNG Terminal \\ UGS Storage Facility \\ PRD 2) Production Facility \\ POW 3) Interconnection with a gas-fired power plant The code assigned to each project serves as a key for the different TYNDP editions and the PCI selection process.
