Half of Russia's major diesel refineries cut output after Ukrainian drone strikes in September 2026
Three of the six largest Russian oil refineries producing diesel fuel significantly reduced or completely halted production in September 2026 following Ukrainian drone attacks, according to Reuters calculations based on fuel market data. The affected plants — together accounting for roughly half of Russia's diesel output — include Rosneft's Syzran and Saratov refineries, which stopped processing crude after strikes earlier this month.
Key points
- KINEF refinery fully halted operations; Volgograd and NORSI were operating at about one-quarter of nominal capacity.
- The six refineries named by Reuters — Omsk, KINEF, Taneco, Volgograd, NORSI and Perm — produce around half of Russia's diesel fuel.
- Rosneft's Syzran refinery (8.5 million tonnes/year, 150,000 barrels per day) stopped on Tuesday after drones damaged its CDU-6 unit (17,000 tonnes/day, ~71% of plant capacity).
- Rosneft's Saratov refinery (7.0 million tonnes/year, 140,000 barrels per day) halted processing from 11 September after another drone strike; its ELZU-AVT-6 primary unit and a main pipeline section were damaged.
- Other strikes in September hit the Slavyansky refinery in Krasnodar Krai, the industrial zone of Nizhnekamsk in Tatarstan, and the Ryazan refinery, where a fire broke out on 6 September.
- The International Energy Agency reported successful strikes on Russian refineries on average every three days in the first eight months of 2026.
- Bank of Russia official Andrei Gangan said the fuel crisis caused by the strikes added 0.7–0.8 percentage points to Russian inflation.
Why it matters
The campaign has eroded roughly half of Russia's diesel production capacity — a strategically significant share — and reportedly pushed Moscow to restrict exports of gasoline, diesel and aviation fuel. The International Energy Agency's tally of successful strikes averaging every three days in the first eight months of 2026 indicates a sustained pressure campaign rather than isolated incidents, with knock-on effects on Russian domestic fuel supply, inflation, and external markets.
What happened
In September 2026, three of the six largest Russian oil refineries producing diesel fuel — KINEF, Volgograd and NORSI, together with Rosneft's Syzran and Saratov plants — significantly reduced or fully halted production following Ukrainian drone strikes, according to Reuters calculations based on fuel market data. KINEF stopped altogether; Volgograd and NORSI continued at roughly a quarter of nominal capacity.
At Syzran, located in Russia's Samara Oblast, drones damaged several facilities including the main CDU-6 crude distillation unit (17,000 tonnes per day, about 71% of the plant's capacity) on a Tuesday in mid-September; the plant's other unit, CDU-5 (7,000 tonnes per day), was already offline for repairs after a July drone strike. Reuters, citing three industry sources, said the Syzran refinery had stopped.
At Saratov, processing halted on 11 September after a further drone attack damaged the ELZU-AVT-6 primary unit and a section of the main pipeline. The Saratov plant had already been suspended on 8 September from equipment damage and fire caused by an earlier drone strike, and had been preparing to resume on 10–11 September.
Other September strikes reported in the material included the Slavyansky refinery in Slavyansk-na-Kubani (Krasnodar Krai), drones hitting the industrial zone of Nizhnekamsk in Tatarstan on the night before Sunday 13 September, and a fire at the Ryazan refinery after a 6 September Ukrainian drone attack. A strike on the Taneco refinery was also reported, though the consequences could not yet be assessed.
The six refineries named — Omsk, KINEF, Taneco, Volgograd, NORSI and Perm — together account for about half of Russia's diesel production. Reuters said the broader pattern of strikes on Russian refineries had reduced fuel output and forced Moscow to restrict exports of gasoline, diesel and aviation fuel. A Bank of Russia official said the resulting fuel crisis added 0.7–0.8 percentage points to Russian inflation. Reuters estimated that repairs at Syzran could take at least a month.
How Ukrainian sources describe it
The single Ukrainian-language source frames the story as a Reuters-based overview that emphasizes the scale of disruption to Russian refining — with half of the major diesel-producing plants affected — and attributes the damage to Ukrainian drone strikes, underscoring the impact on Russia's fuel exports.
Background
The six refineries cited by Reuters — Omsk, KINEF, Taneco, Volgograd, NORSI and Perm — together account for approximately half of Russia's diesel fuel production. KINEF had fully halted operations by mid-September, while Volgograd and NORSI were running at roughly a quarter of nominal capacity.
