Ukraine’s Zaporizhzhia nuclear power station has regained its access to backup electricity from the grid for the first time in six months, after today’s completion of repairs to a second power line under the protection of a localised ceasefire brokered by the International Atomic Energy Agency (IAEA).

The repairs mean that for the first time since May 2025, Zaporizhzhia once again has “redundancy” in its external power supply.

However, the IAEA warned that the external electricity situation at the plant remains extremely fragile. During more than three and a half years of conflict, the site has lost all access to external electricity 10 times. Before the conflict, it was connected to the grid through 10 power lines.
