Spain-Portugal Interconnector Gas Pipeline was a proposed gas pipeline in Spain running to the Portuguese border.[1] The project was cancelled in 2020.[2]


The pipeline would run from Zamora, Spain to the Portuguese border near Vale de Frades, Portugal.

The Spain-Portugal Interconnector Pipeline is included in the first stage of a proposed international project that would continue 162 kilometers across the border to Celorico da Beira, Portugal.[3] The Portuguese section of the pipeline would be known as the Celorico–Spanish Border Pipeline. Both pipelines form part of a larger international pipeline project designed to create a single gas market within the European Union.[4] Some of the gas imported from Spain would also be stored at caverns in the salt dome formations of Carriço, Portugal for potential use in a future emergency.[3][5]

The European Network of Transmission System Operators for Gas (ENTSOG) refers to the project using the project code "TRA-N-168". Together with "TRA-A-283" (Celorico–Spanish Border Pipeline) it is a part of the "WEST 02" project group which is the first stage of the 3rd Interconnection between Portugal and Spain project.[1][3]

The European Union's 2021-2030 National Energy and Climate Plan for Portugal states that the Spain-Portugal Interconnector gas pipeline is directly dependent on completion of the South Transit Eastern Pyrenees (STEP) Gas Pipeline between France and Spain.[6] However, the latter project was canceled in early 2019[7], leaving the future of the Spain-Portugal Interconnector project unclear.[4]


The release of updated project information by ENTSOG in November 2020 included no mention of the project's code "TRA-N-168". ENTSOG's accompanying 'Infrastructure Report' refers to "two cancelled projects" which are investments of REN Gasodutos. The two cancelled projects are the Spain-Portugal Interconnector project and the Cantanhede-Mangualde Gas Pipeline.[2]
