Slated for construction in Portugal's Centro region, the proposed Cantanhede-Mangualde Gas Pipeline would be part of the second stage of a larger international pipeline project linking Portugal and Spain. The project aims in part to import natural gas from Spain for storage at six caverns in the salt dome formations of Carriço, Portugal for potential use in a future emergency.[1] [4]

The Cantanhede-Mangualde pipeline is listed as a European Network of Transmission System Operators for Gas project with the code "TRA-N-285"[1] and as a Project of Common Interest with the code "5.4.2".[3]

The larger international project (known as 3rd Interconnection PT-ES) calls for the Cantanhede-Mangualde pipeline (Stage 2) to be built following completion of the Celorico–Vale de Frades Gas Pipeline and Spain-Portugal Interconnector Gas Pipeline (Stage 1).[1] However, the European Union's 2021-2030 National Energy and Climate Plan for Portugal states that the Celorico–Vale de Frades gas pipeline is directly dependent on completion of the South Transit Eastern Pyrenees (STEP) Gas Pipeline between France and Spain[5], and the latter project was canceled in early 2019[6], leaving the future of the Cantanhede-Mangualde project unclear.[7]


The release of updated project information by ENTSOG in November 2020 included no mention of the project's code "TRA-N-285". ENTSOG's accompanying 'Infrastructure Report' refers to "two cancelled projects" which are investments of REN Gasodutos. The two cancelled projects are the Cantanhede-Mangualde pipeline and the Spain-Portugal Interconnector Gas Pipeline.[2]
