Medgaz runs a total of 757 km from Hassi R'Mel gas hub in Algeria to Almería, Spain. The pipeline runs 547 km as a 48-inch pipeline from Hassi R'Mel to Beni Saf, on the Algerian coast, and then 210 km as a 24-inch subsea pipeline across the Mediterranean to Almería. The project began in 2001; construction began in March 2008, and the pipeline was inaugurated in March 2011. The offshore portion was built by Italian firm Saipem. The total cost was more than €1 billion, i.e. more than $1.4 billion.[2][3]

After BP and Total S.A. withdrew from the project in 2006, the shareholders of Medgaz consortium included, Sonatrach (Algeria), CEPSA (Spain), Iberdrola (Spain), Endesa (Spain), and Gaz de France (France).[4] As of June 2020, after several buyouts, the pipeline was owned by Sonatrach (51%) and Naturgy (formerly Gas Natural Fenosa) (49%).[5] Naturgy financed its increased stake in the pipeline via a €260 million (US$285 million) loan from Santander, ING, Banca IMI and Natixis agreed in November 2019.[6]

In November 2019, the Medgaz consortium awarded Arkad a $50 million contract to build an expansion of the compression station at Beni Saf. The expansion will allow the pipeline to expand from 8 bcm/year to 10.5 bcm/year. The expansion was completed in February 2022.[9][10][11]

The expanded capacity has been reported at 10 bcm/y[9], 10.5 bcm/y[1][11] (and up to 16 bcm/y[1]), or 10.7 bcm/y.[7] A press release from Medgaz states "above" 10 bcm/y.[12]

The expansion project was ultimately estimated to cost €67 million (US$73.91 million).[8]
