Iraq faces 11-gigawatt summer blackout as Iran war cuts gas imports by 67%
With peak demand forecast at 40 gigawatts against 29 GW supply, geopolitical energy dependence becomes humanitarian crisis.
Iraq’s electricity grid will fall 11 gigawatts short of peak summer demand after Iranian gas imports collapsed by two-thirds following strikes on Iran’s South Pars gas field in February 2026. The country faces demand of roughly 40 gigawatts in the coming weeks compared with current production of approximately 29 gigawatts, according to Shafaq News. Iranian gas previously supplied nearly a third to 40% of Iraq’s electricity generation.
The strikes by US and Israeli forces on February 28, 2026, targeted infrastructure connected to Iran’s South Pars gas field, causing an abrupt halt in flows to Iraq and knocking more than 3,000 megawatts offline. Iranian gas imports dropped from 55 million cubic feet per day to just 18 million cubic feet by April, per Kurdistan24. The Iraqi Electricity Ministry projects a 27,000 MW deficit during peak demand periods this summer.
Geopolitical dependence as weapon
Tehran’s control over Iraq’s energy supply has shifted from commercial relationship to political leverage. Middle East Online notes the move serves multiple purposes for Iran: exerting pressure on Washington through Iraq, signalling the limits of Baghdad’s independence in energy matters, and using power shortages to embarrass the Iraqi government domestically.
“The loss of 3,100 megawatts will definitely affect the system and we were well prepared to have our plants ready before the peak season.”

The closure of the Strait of Hormuz on the same day as the South Pars strikes compounded the crisis by cutting Iraq’s oil revenue by approximately 90%, eliminating the budget necessary for emergency fuel purchases from alternative suppliers. Daily revenue losses reached $260-280 million, according to Iraqi News citing economist Mohammad Al-Hasani. Oil production in southern Iraq dropped by more than 70%, with the Zubair field falling from 400,000 to roughly 250,000 barrels per day.
Infrastructure decay compounds crisis
The immediate gas shortage sits atop decades of infrastructure neglect. Transmission and distribution losses exceed 40% of generated electricity before reaching consumers, data from the Baker Institute shows. This compares with Saudi Arabia’s sub-7% losses and a global average of 8%. Iraq simultaneously flares approximately 18 billion cubic meters of gas annually—enough to generate significant electricity domestically if capture infrastructure existed.
A planned power link with the Gulf Cooperation Council, originally scheduled for early 2026, has been delayed until at least the end of August, the Middle East Forum reported. The 500-megawatt interconnection represents a fraction of the deficit Iraq faces but would have provided critical backup capacity during peak hours.
Cascading humanitarian and economic risks
Sustained blackouts in 45°C+ heat threaten hospitals, water treatment plants, and food storage infrastructure. Economic analyst Hilal al-Ta’an described the situation to Shafaq News as “a comprehensive gap between fuel, infrastructure, and demand management—a systems failure in which any disruption to imported gas translates directly into blackout hours for ordinary citizens.”
Brent crude spiked above $120 per barrel in the immediate aftermath of the Strait closure, with the U.S. Energy Information Administration forecasting $115/barrel for Q2 2026. Global LNG export capacity stood one-quarter offline as of early April, with Qatar’s Ras Laffan facility—accounting for roughly 20% of global output—operating at reduced capacity after sustaining damage to 2 of 14 liquefaction trains.
The electricity crisis intersects with Iraq’s ambitions to position itself as a regional transit hub through the Development Road corridor, a $17 billion initiative to connect the Persian Gulf to Turkey and Europe. The Stimson Center notes that sustained power shortages undermine investor confidence in Iraq’s capacity to serve as reliable infrastructure backbone, while dependence on Iranian gas gives Tehran effective veto power over Baghdad’s regional integration efforts.
OPEC production at risk
If grid collapse triggers shutdowns at oil production facilities, Iraq’s 4.5 million barrels per day of capacity—OPEC’s second-largest after Saudi Arabia—faces disruption beyond the current Hormuz-driven cuts. Southern fields already operating at 30% of normal capacity lack redundancy to absorb further power interruptions. Extended outages could force flaring of associated gas or full well shutdowns, requiring months to restore production.
- 11 GW shortfall equals roughly 28% of peak demand—sufficient to cause rolling blackouts of 12+ hours daily in most regions
- 40%+ transmission losses mean even emergency capacity additions lose nearly half their output before reaching end users
- 90% oil revenue loss eliminates fiscal capacity for spot LNG purchases or emergency generation rentals
- GCC interconnection delay removes 500 MW backup option during June-July peak heat
What to watch
Strait of Hormuz reopening timeline determines whether Iraq can restore oil export revenue for emergency fuel purchases. Current flows of 18 million cubic feet per day of Iranian gas remain subject to further disruption if conflict escalates. Domestic associated gas capture projects, delayed for years, cannot materialise before autumn at earliest. The GCC power link scheduled for late August will miss the worst of summer demand. Hospital and water infrastructure resilience will be tested first—watch for reports of treatment interruptions or desalination failures in southern cities. Any shutdowns at major southern oil fields would signal the crisis has crossed from humanitarian to macroeconomic, with implications for global supply at a moment when 25% of LNG capacity remains offline and Brent holds above $100.
