The purpose of this paper is to focus on the proposed Regulation and to offer considerations on some of its provisions, in particular on the move from the national to the regional level of cooperation and on the legislative formalisation of solidarity. [...] The EC identified several weaknesses related to the implementation of the 2010 Regulation, most notably a significant lack of information on several aspects, such as the fulfilment of supply standards, and the insufficient number of bi-directional interconnection points on the EU network. [...] When talking about the security of gas supply, it is relevant to consider the role of gas in the energy mixes of the various Member States. [...] The 2010 Regulation already encouraged a framework for regional cooperation, but the new proposal calls for the elaboration of the Risk Assessments as well as the Plans on a regional level, on the basis of mandatory templates. [...] Several initiatives for gas already exist, such as the Gas Regional Initiatives headed by ACER, the Gas Regional Investment Plans developed by the Transmission System Operators, the cooperation of several Member States under the Gas Platform and through the Union for the Mediterranean, and the regional groups 17 of the Projects of Common Interest.
