Ukraine’s Zaporizhzhia nuclear power plant is reported to have lost external power supply, leading to a full blackout and reliance on backup systems. Multiple outlets say the disconnection is tied to damage on a specific 330 kV line, which protective systems cut off.

Russian-installed management at the plant, quoted in coverage, says the “Ferosplavna” power line was disconnected. Kyiv Post adds operational context, saying the blackout follows the loss of the final working 330 kV line from the Ukrainian grid and counts as the station’s 16th external power blackout recorded in 2026. Other reports describe the plant switching to diesel generators, underscoring the safety implications of operating without grid power.

Across outlets, the common framing centers on what power line failed, whether the plant is fully in blackout, and what backup power it uses. Differences mainly concern the precision of timing, how the event is numbered for the year, and how much attention is given to nuclear safety concerns.
