On 17 August 2009 at 8:13 AM, the hydro-electric plant suffered a catastrophic accident that caused flooding of the engine and turbine rooms, and two 711 MVA electric generators to explode underwater as a result of a short circuit. All other machinery was damaged to some extent, with only four hydro-aggregates ultimately recoverable; the remaining six required replacement. As of 10 September 2012, 75 people, including 1 pregnant woman, were confirmed dead, while one person was still listed as missing forty days after the disaster.
