Russian Attacks Cause Fresh Power Outages in Four Oblasts; No National Schedules

Last editorial update:

Grid & TransmissionSecurity / Attacks

As of the morning of 18 September 2026, Ukrenergo reported new power outages for consumers in Sumy, Dnipropetrovsk, Zaporizhzhia and Kharkiv regions caused by Russian drone and artillery attacks. Restoration is underway where security conditions allow. Separately, weather caused outages in 24 settlements in Zhytomyr. No nationwide consumption-restriction schedules were planned for 18 or 19 September; consumption was up 8.9 % year-on-year at 09:30 due to cloudy weather reducing solar output.

Why it matters

Confirms persistent kinetic risk to grid and generation assets even outside peak winter. While outages remain localised (Sumy, Dnipropetrovsk, Zaporizhzhia, Kharkiv), the pattern elevates insurance, curtailment and location risk for any central/eastern RE or BESS project and reinforces the relative attractiveness of western Ukraine sites for new 5–100 MW development.

Editorial assessment, distinct from the reported development above.
