Zaporizhzhia Nuclear Plant Loses External Power for 24th Time Since Russian Occupation

BLUFAccelerating blackout frequency and a diesel resupply stalled since March make another off-site power loss before late November very likely, edging Zaporizhzhia closer to a cooling-capacity crisis with no viable repair window.

The Zaporizhzhia Nuclear Power Plant lost its only remaining off-site power line, the 330 kV Ferosplavna-1, at 00:44 local time on August 20, forcing automatic startup of emergency diesel generators, IAEA Director General Rafael Grossi said 1. Preliminary assessment located the damage on the Dnipro River's northern bank; manual reconnection failed, and ongoing military activity has prevented technicians from determining the cause 1. Plant management reported radiation levels remained normal and said all measures to maintain safe reactor conditions were in place 2. The story's cited '24th total loss since mid-April' figure is misdated: that count and its Mezha/EU Today sourcing describe an earlier, separate outage on August 4, not this August 20 event. Energoatom's own statement on the August 20 outage instead puts it at the plant's 27th total loss of off-site power since the 2022 occupation began, its 15th-16th this year, a discrepancy independent reporting (UNN, citing Energoatom directly) confirms. The IAEA also disclosed that plant staff and subcontractors were hit by a drone explosion earlier in the week, causing 20 casualties, including one death and three serious injuries, and that the plant's most recent diesel fuel delivery was in March, with a planned May resupply delayed by continued military activity, though the plant reports over ten days of diesel fuel on hand 1.

Analysis
Repeated loss of the plant's sole off-site line, now compounded by a fatal drone strike on staff and a diesel resupply stalled since March, strips redundancy from cooling operations at a moment when technicians cannot reach the damaged line to assess it. Another off-site power loss before November 22 is very likely, driven by unrepaired grid infrastructure on the Dnipro's contested northern bank and an active-conflict environment that has already produced twelve such losses this year alone. Low confidence reflects reliance on IAEA and plant-management statements from a facility under Russian control, with no independent verification of line-damage causation or diesel-stock accounting.
