Russia’s Drone Swarm Targets Small Ukrainian Power Substations, Escalating Energy Disruption

Escalating Drone Campaign Against Small Substations
Since the winter of 2025-2026, Russian forces have intensified aerial attacks on Ukraine’s low-voltage power substations. The Centre for Information Resilience (CIR) mapped 270 verified strikes that combined hundreds of drones and dozens of missiles in single waves, aiming to disrupt electricity distribution to civilian consumers.
Shift in Targeting Strategy
Domestic drone production in Russia has expanded rapidly, allowing a transition from occasional missile strikes on large power plants to frequent, high-volume drone swarms against smaller grid components. This shift gives Russian operators greater latitude in selecting targets, according to CIR investigators.
Key Actors and Organizations
- Russian Armed Forces – conduct the drone and missile attacks.
- Centre for Information Resilience (CIR) – provides geolocated video verification and analysis.
- Joshua Scriven – investigator on CIR’s “Eyes on Russia” team.
- Oleksandr Kharchenko – director of the Energy Research Centre, Kyiv.
- Ukraine’s Defence Ministry & Main Intelligence Directorate (GUR) – supply official casualty and attack figures.
- World Bank – estimates economic damage to Ukraine’s energy sector.
Scale of Attacks: Data and Statistics
- November 2025 – March 2026: >1,000 missiles and 27,000 Shahed-type drones launched (Ukrainian defence ministry).
- Average day: >100 drones fired into Ukraine (CIR).
- Small substations accounted for 58 % of verified attacks Oct 2025-Apr 2026, up from 31 % the previous year.
- Ukraine operates 115-120 high-voltage substations and more than 3,000 smaller transformers (Kharchenko).
- World Bank: $25 billion in direct damage; total rebuilding cost exceeds $90 billion.
Impact on Ukraine’s Energy Grid and Civilians
Frequent strikes have caused power outages lasting up to 18 hours in major cities during the coldest winter period in years. While attacks on distribution substations do not collapse the national grid, they generate localized disruptions that affect tens of thousands of households and impede industrial activity.
Official Statements and Responses
- Russian Defence Ministry: No comment on CIR data.
- Russia: Denies targeting civilians; asserts that attacks on civil energy infrastructure are militarily justified because they degrade Ukraine’s warfighting capability.
- Ukraine: Labels the attacks on civilian power assets as war crimes and blames them for humanitarian hardship.
Criticism and Opposition
Kyiv officials criticize the targeting of small substations as a violation of international humanitarian law, emphasizing that Ukraine’s limited air-defence assets are concentrated on major power plants, leaving the extensive network of smaller transformers vulnerable.
Conflicting Reports and Gaps
CIR’s verification covers 270 strikes, while Ukraine’s defence ministry reports over 1,000 missile launches and 27,000 drones, indicating a discrepancy in the scope of documented attacks. CIR does not classify the specific weapons used in each strike, and the Russian defence ministry has provided no official figures.
Verbatim Quotes
- “Before 2025, it was necessary to partially stockpile the drones in order to amass sufficient volume to overwhelm air defence,” — Joshua Scriven, CIR investigator
- “But now, with the average day in Ukraine seeing over a hundred such drones fired into the country, Russian forces have more latitude in target selection.” — Joshua Scriven, CIR investigator
- “Striking distribution substations isn't going to have a large-scale impact on the wider grid, but it can certainly cause issues at the local level,” — Joshua Scriven, CIR investigator
Future Outlook
The World Bank’s reconstruction estimate underscores the long-term financial burden on Ukraine. Ongoing monitoring by CIR and Ukrainian intelligence suggests that drone-based attacks on small substations will remain a tactical focus for Russian forces as the conflict continues into the next winter season.
