It was decided to shut down the power generation unit №6 in order to ensure its better security, Enerhoatom reports.

"Today, on September 11th, 2022 at 03:41 a.m., the power generation unit №6 at Zaporizhzhia NPP was disconnected from the grid. Currently, it is being prepared for cooling and switching into cold state. For the past three days, the 6th power unit has been operating in an island mode, supplying electricity only for ZNPP auxiliary needs at the critically low power (from 114 to 140 MW), since all power lines connecting Zaporizhzhia NPP with the Ukrainian energy system were damaged by Russian shells”, the report reads.

Last night, after operational capacity of one of these communication lines was restored, it became possible to supply ZNPP with auxiliary power from the Ukrainian power grid. Therefore, a decision was made to shut down power unit 6 and transfer it to the safest state - cold shutdown. "In the event of repeated damage to the lines of communication with the power grid, the risk of which remains high, the ZNPP's auxiliary power supply will be provided by diesel generators, and their operation is constrained by their technology and the amount of available diesel fuel. In order to avoid emergency at the plant, the Russian troops must stop shelling power transmission lines connecting ZNPP to the energy system and create a demilitarized zone around the facility. After that, we will be able to restore power transmission line, relaunch units and ensure further safe operation on ZNPP", Enerhoatom added.
