Accident at Russian hydroelectric plant
The Sayano–Shushenskaya hydroelectric power plant, located on the Yenisei river in Russia, experienced a problem after a hydraulic shock in water pipes caused a flood in the engine room.
The power station was shut down, and backup sources were enabled. The dam across the Yenisei was not damaged and there is reportedly no possibility of territory flooding. Two of ten turbines were destroyed, with a third seriously damaged.
The hydroelectric plant is the most powerful in Russia, supplying several major aluminum plants, including Rusal. It was opened in 1978 and generates more than 23.5 TeraWatt-hours annually.
