Ukrainian state company Energoatom announced that power units under Ukrainian control have reconnected to the national grid. The company conveyed this update through its Telegram channel, emphasizing the ongoing restoration of electricity supply in areas affected by disruption and the broader role of nuclear energy in Ukraine’s grid stability.
According to Energoatom, nine nuclear power units that fall under Ukrainian management are now in operation. The organization noted one of these units is currently limited to 600 MW because the power system cannot absorb the full output at this moment. This limitation reflects the grid’s readiness rather than a fault in the reactor itself and highlights ongoing coordination between operators and transmission networks to balance supply with demand.
In September, the fifth unit at the Zaporozhye Nuclear Power Plant (ZNPP) was brought back online after earlier outages caused by damage to communication lines. Energoatom, the Ukrainian state agency responsible for nuclear energy, reported that this unit has resumed activity and is contributing to the plant’s overall output while other safety and reliability measures remain in place to ensure secure operation.
Meanwhile, the sixth unit at ZNPP continues to deliver electricity to the Ukrainian grid. It currently operates via a backup transmission line with limited capacity but remains a key component of the facility’s response to the ongoing energy needs of the country and the station’s own demand. The operators have stated that the unit is meeting local electricity requirements and maintaining reliability through contingency configurations.
On September 3, the International Atomic Energy Agency (IAEA) reported that the Zaporozhye plant had once again lost connection to the last remaining main transmission line. Despite this, the plant was able to keep operating using a backup line, underscoring the resilience of Ukraine’s nuclear energy infrastructure under stress and the importance of international oversight in safeguarding secure operations during conflict. The IAEA noted that while the loss of the main line posed challenges, the continued operation on backup capability demonstrates committed fault tolerance and ongoing safety protocols across the facility.
