A single explosive-laden drone struck the Khor Mor gas storage facility in Sulaimaniyah governorate on Sunday night, igniting a fire and suspending gas supply to power plants across five major Kurdish cities: Erbil, Sulaimaniyah, Bazian, Chamchamal, and Duhok. The attack knocked 2,500 to 2,800 megawatts of electricity generation off the grid — between 70 and 80 percent of the Kurdistan Region's total capacity. The Kurdistan Regional Government's Ministry of Electricity confirmed it would attempt to keep critical infrastructure — hospitals, water treatment plants — running via hydroelectric stations and plants operating on alternative fuels. That this constitutes the contingency plan tells you everything about the region's energy architecture: there is effectively no backup for the gas supply chain that powers normal life. No group has claimed responsibility. Iraqi Prime Minister Ali al-Zaidi said initial assessments showed no casualties and ordered a joint investigative committee with Kurdish authorities. The timing is significant: the strike comes amid the US-Israel war on Iran, though no direct link has been established. Al Jazeera's Sanad agency verified footage of smoke and flames near the facility. This is the second drone attack on the same facility in two years. That repetition should be the headline. A single gasfield — Khor Mor — serves as the backbone for nearly all power generation in a region of roughly six million people. Striking it once is an attack; striking it twice is a proof of concept for any actor seeking regional leverage. The structural problem is not the drone. It is the concentration. Kurdistan's power grid runs through one chokepoint with no meaningful diversification. Every megawatt that flows through Khor Mor gas is a megawatt that disappears when a single drone gets through. The attack did not need to be sophisticated — it needed only to exist. The investigative committee will likely focus on attribution, which matters diplomatically but not structurally. Whether the attacker is an Iranian proxy, a domestic actor, or an unaffiliated group, the vulnerability is identical. The grid was built for efficiency, not resilience, and one drone just demonstrated the cost of that tradeoff to millions of people sitting in the dark. For Kurdistan's population, this is an immediate crisis with cascading effects: no power means no refrigeration, no communications for many, no water pumping beyond emergency facilities. For regional watchers, this is a signal that critical infrastructure in contested zones remains trivially disruptable — and that the cost-benefit calculus for attackers is extraordinarily favorable.
