Assessment
What the evidence currently supports
OHCHR documented a systematic Russian campaign against Ukrainian electricity and heating infrastructure during the 2025–26 winter. Ukraine simultaneously expanded attacks on Russian refineries, fuel storage and maritime logistics. Recent Ukrainian claims included strikes on the Perm and Ryazan refineries on July 29 and the Saratov refinery on August 3, but the operational effects of individual strikes were not independently established.
OHCHR count of strikes on combined heat-and-power plants and other heating infrastructure over the same period.
Combined Perm and Ryazan capacity cited by Ukraine after the July 29 attacks; damage effects were not independently verified.
Change log
What changed
- OHCHR's June 29 report quantified the scale of the previous winter's attacks and warned that generation capacity could not be fully restored before the next winter.
- Ukraine reported strikes on the Perm and Ryazan refineries on July 29, extending its campaign more than 1,500 kilometres from Ukraine in the Perm case.
- Ukraine reported striking the Saratov refinery, Engels air base and a Kaluga-region fuel depot on August 3 as long-range attacks continued in both directions.
Open questions
What remains uncertain
- A reported hit or visible fire does not establish how much refining capacity was lost or for how long.
- The Perm, Ryazan and Saratov target and damage accounts originated with Ukrainian authorities and were not fully independently verified.
- OHCHR also documented Ukrainian attacks that caused power outages in Russia's Belgorod region and occupied Crimea.

Read the scoring method
Evidence quality weighs source authority and directness; corroboration rewards independent agreement; recency reflects how closely sources track the latest material change; source diversity rewards different institutions, geographies, and source classes. The displayed score is the rounded weighted composite: 35%, 30%, 20%, and 15% respectively.

01supported98/100
Russian forces systematically and repeatedly attacked Ukrainian electricity and heating infrastructure during the 2025–26 winter.
OHCHR based its finding on interviews, field and hospital visits, satellite material and open-source analysis, and published facility-level attack counts.
The counts cover a defined reporting period and should not be treated as a complete war-wide total.
02developing74/100
Ukraine's long-range campaign is reaching major Russian refineries and other logistics nodes, but its precise industrial impact remains unclear.
AP corroborated attack reports with regional statements and observable fires in some cases, while explicitly noting that the claims and damage could not be fully verified.
Do not convert nominal facility capacity into an estimate of production actually lost.
Material developments
