Vienna, Sep 4 (TIWN) The International Atomic Energy Agency (IAEA) has said that the Zaporizhzhia nuclear power plant in Ukraine has once again lost connection to its last remaining main external power line but the facility continues to supply electricity to the grid through a reserve line.

The agency’s experts stationed at the Zaporizhzhia plant were told by Ukrainian staff on Saturday that the facility’s fourth, which is also the last still operational, 750-kilovolt power line was down. A similar incident occurred last week amid shelling on the plant, Xinhua news agency reported.

The three other main external power lines were lost earlier during the Russia-Ukraine conflict, according to an IAEA statement.

The plant is now relying on a reserve line, which links the facility to a nearby thermal power plant, to deliver electricity to the external grid. The reserve line can also provide backup power to the plant if needed, IAEA said.
