An Attrition Strategy Identified by Investigators

The Independent International Commission of Inquiry on Ukraine, mandated by the United Nations Human Rights Council, published severe findings on October 26, 2026. Repeated attacks on electricity and heating constitute war crimes, it concludes, for deliberate strikes on civilian objects. They also constitute crimes against humanity, for the other inhumane acts described, given their systematic nature and their effects on the population.

Methodological precision matters. These are the findings of a commission of inquiry, not a criminal verdict. They nonetheless rest on a substantial documentary base: 255 testimonies from people who endured these deprivations across several Ukrainian regions, supplemented by information from doctors, non-governmental organizations and Ukrainian authorities. The Commission describes waves of attacks sometimes involving hundreds of drones and missiles. It studied their consequences since autumn 2022, with particular attention to the harsh winter of 2025-2026.

Why Strike Energy: The Domino Effect

Interdependent Services

The choice of this target stems from the very structure of cities. When temperatures dropped to -21 °C, millions of residents experienced long interruptions of electricity, heating, water or gas. Damage to a power plant, a substation or a heating facility does not stay local. It cascades into water distribution, elevator operation, continuity of care and school openings.

Neighborhoods supplied by large centralized heating networks are the most exposed, because a single facility failure hits many buildings at once. Elderly people and those with reduced mobility pay the heaviest price. Some can no longer use an elevator or reach a shelter during an alert. This chain of dependencies is what turns material damage into lasting deprivation. The Commission concludes that the strikes form part of a policy aimed at depriving the population of electricity and essential services.

Pressure That Continues

The conflict has shown no pause. On October 26, the Russian Ministry of Defense claimed strikes on electricity production facilities in Kharkiv and the Khmelnytskyi region. These claims come from a party to the conflict and must be distinguished from the investigators' findings. They nonetheless show that the campaign continues as winter approaches.

Europe, a Stakeholder in Ukrainian Resilience

The Ukrainian power grid has been synchronized with continental Europe's since March 2022. This connection enables electricity exports from the European Union to Ukraine. It makes the robustness of the Ukrainian system a concrete energy cooperation file, not merely a humanitarian matter.

The European effort is quantified. The European Commission states it has mobilized more than €4 billion since the start of the full-scale invasion for Ukrainian energy security. In February it announced an envelope of €922 million for the winter of 2026-2027, intended notably for production, grid robustness and heating. Its tally reports more than 11,000 generators and 7,000 transformers supplied. These equipments are spare links in a chain that the strikes seek to break.

For France, the link runs first through European solidarity, interconnections and the protection of critical infrastructure. Caution is required here: available elements do not allow attributing any quantified effect of these attacks on French households' electricity bills.

Repairing Is No Longer Enough: Holding Out During Strikes

The operational challenge has changed in nature. It is no longer only about restoring what was destroyed, but about maintaining minimal supply when several facilities are hit at the same time. Ukrainian communities are developing modular boiler plants, generators and decentralized production units.

The logic is dispersion. By spreading backup resources, a power failure is prevented from turning into a simultaneous interruption of heating, water and care. A single unavailable large facility no longer shuts down an entire neighborhood. The priority as winter approaches is therefore twofold: repair damaged facilities and make the system less vulnerable to cascading failures.

This adaptation has its limits. Its effectiveness depends on available fuels, spare parts, site protection and the capacity of teams to intervene under the threat of strikes. A fleet of generators without fuel or maintenance protects no one, and logistics becomes a strategic issue in its own right.

What the Facts Allow Us to Say, and What They Do Not

Several caveats are in order. The investigators indicate they also examined Ukrainian attacks against energy infrastructure located in Russia and in occupied territories. They specify they could not study their effects for lack of access and response from Russian authorities. The picture is therefore asymmetric: it reflects what the Commission was able to document, not a complete comparison of the two sides.

The regulatory monitoring of the file, which lists 168 recent entries including decisions of the Council of the European Union dated October 26, 2026 amending common foreign and security policy decisions, provides only titles. Without the content of these texts, we do not link them to the analysis above. The supplementary open data request also failed, which limits quantified contextualization beyond the elements cited.

A Proportionate Conclusion

The facts establish three points. UN investigators consider the strikes on energy a systematic policy. The effects cascade from one service to another, hence the severity of the winter impact on civilians. And Europe is engaged through the interconnection of its grid and more than €4 billion in cumulative aid. They allow neither forecasting how the winter of 2026-2027 will unfold nor measuring its repercussions on European consumers. The test of the coming weeks will be the Ukrainian system's capacity to maintain, despite the strikes, a minimal service of heating, water and care.
