The Iraqi Ministry of Electricity has announced that Iranian gas supplies to Iraq have ceased entirely, removing more than 3.1 GW from the national grid following a major strike on Iranian gas infrastructure (Iraqi News Agency, 18/03/2026). A Ministry spokesperson confirmed that gas flows fell from 19 mcm to zero, delivering a severe blow to electricity generation.
The disruption followed reports from Iranian media that several facilities linked to the South Pars gas field in the Assaluyeh energy zone, located on Iran's southern Gulf coast, were struck by missile attacks. South Pars, situated in Bushehr province, is part of the world's largest offshore gas reservoir, shared between Iran and Qatar, making it a critical hub for Tehran's energy exports.
Iraq is heavily dependent on Iranian gas to power its plants, particularly in the south, leaving the country highly exposed to supply disruptions. Iran supplies Iraq with 50 mcm/day, accounting for roughly one-third of the country's energy needs (Anadolu Agency, 18/03/2026).
At the end of 2024, Iraq had an installed power capacity of 34 GW, with gas accounting for 69% of this capacity, oil for 26%, and hydropower for 5% (Enerdata Global Energy Research).
