Both crude distillation units at the Moscow Refinery burn and the plant halts: Russia says it downed 1,110 drones overnight
At the refinery in Kapotnya, which supplies 40% of Moscow's fuel market, the AVT-6 unit processing 21,400 tonnes a day and the EURO+ unit processing 18,800 tonnes both burned on the morning of 20 September. Repairs are expected to take weeks.
The Moscow Refinery, owned by Gazprom Neft, was struck in a drone attack in the capital's Kapotnya district on the morning of 20 September 2026. According to a report published by Ukrainska Pravda at 07.56 on 20 September, the plant has an annual capacity of 11 million tonnes; it supplies roughly 40% of Moscow's fuel market and 70% of the Moscow region's petrol and aviation fuel demand. Initial reports said the ELOU-AVT-6 unit had been hit. The following day, in a report by the same outlet citing Reuters, both crude distillation units were said to have burned: the AVT-6, processing 21,400 tonnes a day and accounting for 53% of capacity, and the EURO+ combined unit, processing 18,800 tonnes a day and accounting for 47%. The plant halted crude processing and sources said repairs could take several weeks. In 2024 the refinery processed 11.6 million tonnes of crude oil and produced 2.9 million tonnes of petrol, 3.2 million tonnes of diesel and 1.3 million tonnes of bitumen.
Sources conflict on the scale of the attack. According to a Russian Ministry of Defence statement carried by TASS, 1,110 Ukrainian fixed-wing drones were shot down overnight over the Belgorod, Bryansk, Kursk, Ryazan, Tula, Kaluga, Vladimir, Nizhny Novgorod, Tambov, Voronezh, Lipetsk, Smolensk, Oryol, Rostov, Volgograd, Saratov, Samara, Krasnodar and Moscow regions, as well as Crimea and the Black Sea. Moscow Mayor Sergei Sobyanin reported that 450 drones approaching the capital had been intercepted and described the attack as the largest to date. Russian reports cited by the Kyiv Independent claimed that more than 1,600 drones had been downed across Russia. None of these three figures could be independently verified; the figure of 1,110 was announced through a state agency.
The attack coincided with the third and final day of the State Duma election held in Russia on 18-20 September. According to the Kyiv Independent, a woman was killed and five people, two of them children, were wounded in Sofyino in the Moscow region; about 400 people were evacuated in Ramenskoye because of a fire on the roof of a 21-storey building. Flights were temporarily restricted at Domodedovo and Zhukovsky airports, and Saratov airport was also affected. According to the same report the Moscow Refinery was also damaged in June 2026 and has been running at reduced capacity since then.
Talay assessment
Bottom line
Two distillation units halting at once at the single plant that covers 70% of the Moscow region's petrol demand turns the attack from a symbolic act into a physical supply interruption. Repairs are expected to take several weeks, during which the capital's replacement fuel will have to be hauled from distant refineries. The most likely direction is a widening of export restrictions to protect the domestic market, and continued regional rationing.
Likely effects
- Moscow's fuel supplyNegativeWeeks
The halt at a plant producing 2.9 million tonnes of petrol and 3.2 million tonnes of diesel a year requires replacement volumes to be brought to the capital by road and rail from distant regions; the logistics cost feeds into pump prices.
- Russian air defenceNegative1–6 months
The claim that 1,110 drones were downed in a single night points to a saturation attempt beyond the previous record of 822; 450 were intercepted on the approach to the capital. Defensive stocks are being consumed faster.
- Russian fuel exportsNegative1–6 months
Taking 11 million tonnes a year of capacity out of service increases the pressure to prioritise the domestic market; exportable volumes of petrol and diesel narrow.
- Fuel prices for TürkiyeNegative1–6 months
A narrower pool of exportable Russian product pushes product margins higher in the Black Sea basin; Türkiye may see upward pressure on the cost of imported diesel.
Possibilities, ranked
- 1Repairs take weeks, a partial return55%
One of the AVT-6 or EURO+ units is partly brought back within a few weeks and the plant begins running at reduced capacity.
Watch: An announcement from Gazprom Neft or Russian officials that processing has resumed at the plant.
- 2The outage drags on and export curbs widen30%
Damage to both units proves deep; rationing spreads in the Moscow region and fuel export restrictions are extended to petrol as well.
Watch: The announcement of a new ban or quota on petrol exports.
- 3A new wave of attacks hits the plant again15%
The same plant is targeted again before repairs are complete; 11 million tonnes of capacity stays out of service for months.
Watch: Reports of a new fire in Kapotnya or a Ukrainian General Staff statement on a second strike.
