ENTSOG South-North Corridor GRIP 2017 - Main Report

8.4.2 INTERCONNECTION WITH SLOVENIA

In line with the expected increase in gas consumption in the area of Koper (Slovenia), taking into account the objectives of the European Directive No. 2009/73/EC and existing local infrastructure, the Italian MiSE and the Slovenian Ministry of Infrastruc- ture agreed to build a new interconnection pipeline between the networks of Snam Rete Gas and Plinovodi in the area of San Dorligo della Valle-Osp and to support the participation of both companies in the development of a coordinated interconnec- tion project. Snam Rete Gas and Plinovodi have defined a technical agreement that establishes the main technical elements of the project, such as the transmission capacity, taking into account the sizing of the pipeline, the minimum contractual pressure at the interconnection point and the maximum operating pressure. Under the agreement, the project foresees new capacity at the new exit point of the national network of San Dorligo della Valle amounting to about 0.3MSm³/d. This project is still awaiting a final investment decision and commissioning is currently planned for 2023.

8.4.3 ADDITIONAL SOUTHERN DEVELOPMENTS Snam Rete Gas ten-year development plan also contains a non-FID project aimed at the expansion of the South-North transmission route, which includes a series of pipelines and related plants. The project would create additional transmission capacity to facilitate gas from a possible second new entry point in Southern Italy.

8.4.4 IMPORT DEVELOPMENTS FROM NORTHEAST The project involves the construction of new pipelines to increase the transmission capacity from northeast and the connection of a regasification terminal in the northern Adriatic area (which might possibly be the “Onshore LNG terminal in the Northern Adriatic”, included in ENTSOG TYNDP 2017 map as LNG-N-217). A final investment decision has not been taken yet.

8.4.5 SARDINIA METHANISATION

The project includes the realisation of the natural gas transport network of Sardinia island interconnected with the new entry points from LNG plants. In accordance with the “Energy and Environmental Plan of Sardinia Region 2015–2030” the gas supply of the island network is guaranteed by LNG plants whose number and localisation are under consideration. Nevertheless, the project is designed to reach security of supply and flexibility also with a single supply entry point. The project includes a backbone National Network of about 380km with diameter DN650/DN400 and regional network pipelines of about 190 km with diameter DN400/DN150 to supply the main consumption areas of the Region. The project is planned in three phases: the beginning will be in 2017 and 2018 and the completion between 2020 and 2022.
