Ten-Year Network Development Plan 2017 Main Report |

Based on the experience of TYNDP 2015 and 2
nd
PCI selection process, ENTSOG
identified that the High Infrastructure level, due to the elevated number of compet-
ing initiatives included, had limited added-value, for both the TYNDP Energy System
Wide assessment and the Project-Specific cost-benefit analysis of projects. How
ever, the infrastructure level is maintained in line with the CBA methodology in force.
Yet, following ACER Opinion on TYNDP 2015 on better and more realistic handling
of projects, the Assessment Chapter covers the comprehensive evaluation of the
Low, Advanced and 2
nd
PCI list Infrastructure Levels. Results of the assessment of
the High Infrastructure Level are made available in Annex E.
In line with the TEN-E Regulation and the CBA methodology the TYNDP provides a
common basis for the Project-Specific CBA of each PCI candidate (see Annex F).
This involves the assessment of different infrastructure levels of the gas infrastruc-
ture based on the level of maturity and PCI status of the projects. The TYNDP will be
used by the Regional Groups as a background when considering the Project Specif-
ic CBAs of the candidate projects for the 3
rd
PCI List.
