Operated by the Portuguese energy infrastructure company REN (Redes Energéticas Nacionais), the Campo Maior-Leiria Pipeline is a key component of Portugal's natural gas transmission network, along with the Valença do Minho-Braga Pipeline, the Leiria-Braga Pipeline and the Setubal-Leiria Pipeline.

Since commencing operations in January 1997, the pipeline has mostly been used to import gas from Spain for distribution in Portugal. However, with the opening of the Sines LNG Terminal on Portugal's Atlantic coast in 2004, Portugal has also begun importing a significant percentage of its natural gas by sea. In January 2019, following a Europe-wide cold snap that brought freezing temperatures to Spain, Portugal exported gas to Spain via the Campo Maior pipeline for the first time in its history.[9]


The SciGRID_gas combined IGG gas transmission network data set refers to the pipeline as INET_PL_96.[10]
