South-North Corridor GRIP 2017
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.
