The strike damaged the CDU-5 (AVT-5) primary crude distillation unit — the plant's main refining unit . This unit accounts for roughly 25% of the plant's production capacity, with a processing capacity of 12,000 tonnes per day .

Immediate Consequences: Shutdown and Casualties

The entire refinery suspended operations on June 24 and halted all oil processing . Local authorities confirmed fatalities from the incident's fallout, though specific numbers are not detailed in available sources .

Parallel Damage to the Moscow Oil Refinery

The NORSI strike did not happen in isolation. In the same period, the Moscow Oil Refinery (also called Kapotnya) was hit by two separate Ukrainian drone strikes:

• On June 12, 2026, one or more drones struck a refining unit .
• On June 18, 2026, five or more drones hit the refinery's only other primary crude processing unit, as well as oil and oil product storage facilities .

The two strikes together disabled both of the plant's main crude processing units, knocking out 100% of its primary oil refining capacity, according to Reuters .

Contribution to Russia's Worst Fuel Crisis

The NORSI shutdown occurred on top of a wave of earlier drone strikes. By mid-June 2026, Ukraine had hit 8 of Russia's 10 largest refineries across 16 separate attacks in May alone . The cumulative effect was described by The Moscow Times as having "set the Russian oil refining industry back two decades" and created "the worst fuel crisis in history" for Russia .

• By the first week of June 2026, Russia had lost roughly one-third of its refining capacity — 2.14 million barrels per day idle .
• Russia's daily gasoline output fell by ~25% compared to the June 2025 daily average, dropping to about 90,000 tonnes per day .

Fuel Rationing Spreads Across Russia

As of June 25, 2026, fuel rationing measures were in place in at least 56 Russian regions, according to The Moscow Times . Major gas station chains introduced strict limits — for example, up to 20 liters of AI-92/AI-95 gasoline and up to 40 liters of diesel per customer in Moscow, St. Petersburg, and Tatarstan . RFE/RL reported at least 17 regions with mandatory government-imposed restrictions, with dozens more affected by private company limits .

The Kremlin's Response: Quality Over Quantity

The sources confirm that Russia quietly let refiners sell lower-grade Euro-3 fuel, allowing gasoline with 15 times the EU sulfur limit to keep pumps supplied . However, specific reporting on the Kremlin formally considering a diesel export ban in June 2026 is not captured in these sources. The Moscow Times noted in mid-June that "the Kremlin's options are shrinking" — including potential export restrictions — but the available evidence does not contain a direct, confirmed report that a diesel export ban was under active consideration at that point .
