ENTSOG TYNDP 2015 - Annex F – Methodology

1 General considerations on the ESW-CBA Methodology Following the requirements of the New TEN-E Regula- tion, ENTSOG has developed an Energy System-Wide Cost-Benefit Analysis (CBA) methodology supporting the selection of Projects of Common Interest (PCI). This methodology is composed of a TYNDP-Step, which is a part of this Report, and a Project Specific-Step to be applied by promoters of projects which are candidates for PCI status, the first step being an enabler of the latter. This annex describes the part of the methodology, approved by the European Commission on 4 February 2015, which has been applied in this Report. The following graph illustrates the link between the two steps of the methodology.
