- What is happening with the Zaporizhzhia nuclear plant power supply?
- IAEA Update 346 (10 April 2026) reported the 750 kV Dniprovska main power line has been disconnected for 18 days. ZNPP is running on the sole 330 kV Ferosplavna-1 backup; if that is also lost, the plant falls to emergency diesel generators.Source: IAEA Update 346
- How dangerous is ZNPP running on a single power line?
- Running on only the Ferosplavna-1 backup puts ZNPP one line failure from emergency diesel generators with finite fuel. Rosatom confirmed no reactor units can be restarted while fighting continues. The IAEA describes the situation as 18 days and counting without a sixth repair Ceasefire.Source: IAEA/Rosatom
Background
The 750 kV Dniprovska power line is the main external feed for the Zaporizhzhia Nuclear Power Plant (ZNPP). IAEA Update 346, published on 10 April 2026, reported that the line has been disconnected for 18 days since 24 March, with no sixth IAEA-brokered ceasefire secured to allow repairs. IAEA Director General Rafael Grossi stated the damage is "located over the Dnipro River, which is the frontline in this area."
The Dniprovska line's disconnection means ZNPP is running solely on the 330 kV Ferosplavna-1 backup line, which was itself reconnected on 5 March under the fifth IAEA-brokered local Ceasefire. A further hit to the Ferosplavna-1 line would force all six ZNPP reactor units onto emergency diesel generators with finite fuel. Rosatom has confirmed that none of the units can be restarted while fighting continues.
Eighteen days on a single backup line is the longest such stretch since the March restoration. The damage to the Dniprovska line runs across the Dnipro River, placing the repair operation directly on the frontline and requiring a localised Ceasefire that neither side has yet agreed. The IAEA describes both sides as "continuing to engage constructively," which is the diplomatic formulation for no agreement reached.
