The Sayano–Shushenskaya hydroelectric power station, located on the Yenisei River in Russia, experienced a problem after a pressure surge caused water pipes to burst, flooding the engine room. The water triggered an explosion in a transformer.

Ten workers were confirmed dead and as many as 68 more injured. Some are still missing.

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.
