SayanoShushenskaya Hydroelectric Power Station
August 17, 2009
Sayano-Sheshenskaya is the largest power plant in Russia and the world's sixth-largest hydroelectric plant. On August 17, 2009, the station's engine and turbine rooms flooded and a transformer exploded. Seventy-five people died in the explosion.
In a 2007 review, 85 percent of the station's equipment had been deemed obsolete. Representatives from RusGidro, owners of the plant, claimed that all necessary upgrades had been made to the facility prior to the accident.
The longterm impact:
The accident resulted in an oil spill that released around 40 tons of oil into the Yenisei River, which flows into the Arctic Ocean. Around 400 tons of trout in two fisheries were killed as a result. The plant's damaged turbines were reopened in 2010.
Workers remove snow and ice at the Sayano-Shushenskaya hydroelectric power station, with a huge block of ice at its foot formed because of the Yenisei River water running through an open spillway with low air temperatures, near the Siberian village of Cheryomushki, about 323 miles south of Krasnoyarsk, January 30, 2010.
