Algerian gas supplies to Spain this week were briefly impacted by a maintenance problem on a subsea pipeline linking the two nations.
Spanish energy utility Enagas said the temporary reduction had no effect on the country's security of supply.
Running across the Mediterranean Sea between Beni Safi on Algeria’s coast and Almeria in Spain, the Medgaz pipeline is owned by Algeria's state-owned Sonatrach and a partnership of Spain’s Naturgy and private equity player Blackrock.
Spain also used to import Algerian gas via the Maghreb-Europe Pipeline (MEP) that runs through Morocco and across the Strait of Gibraltar.
However, Algiers last year cut supplies after a diplomatic dispute with Rabat over the Western Sahara and Morocco's alleged support of independence-minded groups within Algeria.
Morocco can now use the MEP to import gas from Spain — as long as this gas did not originally come from Algeria — and later export it from assets such as Chariot’s Anchois offshore gas project.
In a statement issued on 24 July, Enagas said: “According to information received from Medgaz, during routine maintenance work at the Beni Saaf compression station, there has been a temporary cessation — of two hours duration — of the flows that depart from the Algeria plant to… Almeria.”
The company said this caused throughput to fall briefly but stressed that at no time did output stop.
Enagas said: “The problem has been solved and flows are recovering normally.”
Medgaz is a vital supplier of gas to Spain, albeit the Iberian nation is well served by liquefied natural gas import terminals.
From 1 July this year through to the end of 2026, the pipeline’s firm capacity will be about 1.4 million cubic metres per day, according to Medgaz, before this volume more than doubles to 2.86 MMcmd from 1 November 2026 until 31 March 2031.
