The Russian-occupied Zaporizhzhia Nuclear Power Plant (ZNPP) temporarily lost external electricity supply overnight on June 3 after damage to a power line linked to a drone strike on the Nikopol substation.
Ukraine's state nuclear operator Energoatom said on Telegram that the outage occurred at 23:44 after the Ferosplavna-1 transmission line was disconnected, cutting off the plant's external power supply, Ukrinform reports.
During the blackout, all critical systems at the plant were maintained using backup diesel generators.
Energoatom said this was the 17th blackout at the occupied plant since Russian forces seized it, and the fifth since the beginning of 2026.
