It is intended to supply power to the key facilities - water treatment, control, turbine and reactor buildings.

Cable routing and cubicles assembly are being performed inside the building. Each cubicle will control one or another piece of NPP equipment. In case of emergency or short circuit, all the signals from the normal operation power supply building will be timely transferred to the plant control building.

JSC SEM construction electricians assembled 10kV sections - embedded parts, cable penetrations - and installed 140 electric cabinets, grounded them and installed the connectionbus and cables. The installed equipment is energized normally.

The installation of the 10/0.4kV transformer stations is ongoing. The 0.4kV cabinets are planned to be installed soon. JSC SEM specialists are also supposed to lay 2000 km of cables at the second power unit to energize the plant auxiliaries in a standard manner. This will allow to perform process systems flushing with the unsealed reactor next year.
