Balakovo nuclear power plant is located in the city of Balakovo, Saratov Oblast, Russia, about 900 kilometers south-east of Moscow. It consists of four operational reactors; a fifth unit is still under construction. Owner and operator of the nuclear power station is Energoatom.

Balakovo is the partner power station of Biblis Nuclear Power Plant.

In 27 June 1985, during initial startup of the reactor 1, due to a human error (caused by inexperience and haste) a pressurizer relief valve unexpectedly opened and 300 °C hot steam entered the staff work area. 14 people were killed. This event is quoted as one of the predecessors of the Chernobyl disaster.
