IEA warns extreme heat will stress Iraq's transmission and distribution infrastructure

Iraq Electricity Grid Resilience is tested as extreme heat, sand and dust storms, and peak demand strain transmission and distribution networks, reducing capacity and reliability while accelerating the need for climate adaptation, microgrids, and interconnections.

A new national climate resilience assessment warns that Iraq's electricity system faces intensifying physical stress from rising temperatures, more frequent heatwaves, and recurring sand and dust storms. The report highlights that the combined effects will pressure transmission and distribution assets during peak summer conditions, with implications for capacity, equipment lifetimes, and service reliability.

Projected increases in days above 40 C will broaden the share of the network exposed to extreme heat, making stable grid operations during heatwaves more difficult and prolonging seasonal stress on crews and equipment. For broader context on heat impacts across regions, see world heat electricity for comparable system-wide challenges observed elsewhere.

The assessment notes that Iraq already contends with exceptionally high technical and non-technical losses, estimated at 50-60%, and that heatwaves can further increase transmission losses and complicate balancing amid surging cooling load. Utilities evaluating mitigation options can draw lessons from approaches summarized in us grid heat resilience aar dlr vpps, including ambient-adjusted and dynamic line ratings, virtual power plants, and targeted demand response, adapted to local conditions.

Generation performance is also at risk. Higher ambient temperatures reduce the mass flow of air through gas turbines, lowering output and efficiency, with combined-cycle plants particularly susceptible under hot conditions. The assessment indicates that these derates, coincident with peak demand for cooling, tighten operating margins and can amplify supply scarcity and cost pressures, trends mirrored in coverage such as extreme heat boosts us electricity bills, which underscores consumer impacts during prolonged heat events.

Sand and dust storms have increased in number and intensity in recent years, adding operational hazards for transmission lines, substations, and thermal plants. Reduced visibility, airborne particulates, and abrasive deposition complicate inspection, switching, and maintenance.

The assessment outlines adaptation priorities: accelerate distributed generation and microgrids capable of islanding during widespread disruptions; diversify the generation mix; strengthen data, forecasting, and disaster risk management; and build regional interconnections to share reserves and reduce localized shortfalls. Recent cross-border projects linking Iraq to neighboring systems are cited as steps that can bolster stability in the hottest months. The consequences of insufficient preparation are familiar to many jurisdictions, as illustrated by reports like california faces blackouts, reinforcing the urgency of proactive upgrades before peak season intensifies.

Policy follow-through is central to delivery. The assessment recommends integrating climate risk and impact analyses into project approvals, defaulting to more resilient technologies for critical processes, and hardening assets against both physical and cyber threats. Embedding resilience criteria in grid codes, procurement, and financing frameworks can signal priorities to investors and operators, while data-sharing and emergency planning help sustain reliable service as heat, aridity, and dust events escalate.
