This was reported by Energoatom.
It noted that on that day, at 10:30 a.m., the last fourth line of its connection with the Ukrainian power system, the ZNPP-Dniprovska OHL-750 kV, was disconnected due to a short circuit about 100 km north of the plant. At the same time, three other lines were damaged earlier during Russian shelling.
According to the IAEA, at that time, ZNPP was receiving external power from the only available 330 kV backup power line.
In addition, there was a partial blackout of power unit No. 4 with the automatic switching on of a diesel generator, which was manually turned off 10 minutes later. Energoatom noted that this indicates a problem with the power supply of the nuclear facility.
"Ukrainian specialists repaired the damaged 750 kV line at 8:52 p.m. By this time, Zaporizhzhia NPP was on the verge of another blackout almost all day in case of a blackout of the 330 kV backup line," the company emphasized.
Energoatom reminded that since the Russian seizure of ZNPP, it has repeatedly lost an external power source, and the plant has already experienced seven complete blackouts and one partial blackout.
