Ukraine Drone Strikes Disrupt Multiple Russian Energy Facilities

Ukraine has stepped up drone strikes on Russian energy infrastructure in recent months, hitting oil refineries and a gas processing plant in several regions between late March and mid-May 2026. The attacks have sparked fires and forced some sites to halt or suspend operations, according to officials and industry sources. Several facilities cited in the report account for significant portions of Russia’s refining and gas-processing capacity.

On May 7, the Perm oil refinery stopped processing after a drone attack caused a fire and damaged equipment, industry sources said. The refinery processed about 12.6 million metric tons of oil in 2024.

On May 13, debris from a Ukrainian drone attack caused a fire at a gas processing plant in Russia’s Astrakhan region, the local governor said. The facility has annual capacity of 12 billion cubic meters of gas.

In late April, a major fire was reported at the Tuapse oil refinery following a drone attack. The refinery, which has production capacity of about 12 million tons per year, halted operations after the incident, officials and industry sources said.

Refineries reporting suspensions after April strikes

Two Rosneft facilities were among the sites cited as suspending operations following April 18 drone attacks. Rosneft’s Syzran refinery suspended oil refining after processing equipment was damaged, industry sources said. The Syzran plant is able to process 8.5 million metric tons per year and processed 4.3 million tons of crude in 2024, according to the same sources.

Primary oil processing at the Rosneft-operated Novokuibyshevsk refinery has also been halted since April 18 after a drone strike, industry sources said. In 2024, the refinery processed 5.74 million metric tons of crude, those sources said.

NORSI, described as Russia’s fourth-largest oil refinery, suspended operations on April 5 after a Ukrainian drone attack, industry sources said. The refinery has capacity of 16 million metric tons per year.

Kirishi output and restart timeline

The Kirishi oil refinery reported fires from drone attacks in late March. The plant produced 2 million tons of gasoline and 7.1 million tons of diesel last year, and partial restarts were anticipated within a month.

The latest incidents add to a growing list of reported disruptions at energy sites as the war continues, with officials and industry sources monitoring whether suspended units return to operation and how quickly damaged facilities can resume output.
