Sayano-Shushenskaya Dam

On the Yenisei River, the 6.4GW Sayano-Shushenskaya hydroelectric power facility is Russia's largest hydropower plant. RusHydro, a hydroelectricity corporation, manages the facility. Its 242m-high arch-gravity dam has a 1.06km crest length and a 25m crest width.

When one of the turbines of the Sayano-Shushenskaya plant failed in 2009, the building is flooded, killing 75 people and spilling 40 tons of oil into the Yenisei River. The plant came under fire. All ten turbines were damaged in the disaster, with at least three of them destroyed. In the aftermath of the accident, the factory was modernized with the installation of an enhanced vibration monitor as well as other safety precautions. Following the accident, the facility was temporarily shut down, resulting in a loss of 2.5 percent of Russia's electrical production. Although the plant resumed operations in February 2010, the repairs were completed by November 2014.
