1. Abstract This research was aimed to investigate the industrial case problem, of the “Sayano-Shushenskaya Hydroelectric Power Station”, which had happened on August 17,2009, whereby turbine 2 of the Sayano–Shushenskaya hydroelectric power station near Sayanogorsk in Khakassia, Russia, broke apart violently. The turbine hall and engine room were flooded, the ceiling of the turbine hall collapsed, 9 of 10 turbines were damaged or destroyed, and 75 people were killed. The entire plant output, totaling 6,400 MW and a significant portion of the supply to the local grid, was lost, leading to widespread power failure in the local area, and forcing major users such as aluminum smelters to switch to diesel generators. 2. Introduction Sayano–Shushenskaya hydroelectric power station is located on the Yenisei River, near Sayanogorsk in Khakassia. Before the accident, it was the largest hydroelectric power station in Russia and the sixth-largest hydroelectric power station in the world, by average power generation. The plant is operated by RusHydro. On 2 July 2009, RusHydro announced the station’s all-time highest electricity output per 24 hours. Seventy percent of the load on the East Siberian grid consists of four very large aluminium smelters. The Bratskaya hydro plant (4500MW) was normally the lead plant on the grid, with the responsibility of following load and contributing to grid frequency control. Sayano Shushenskaya was normally base loaded, and not following load swings.The construction of the power plant includes an arch gravity dam and a spillway (under construction). The arch gravity dam is 245.5 metres high with a solid left bank dam 246.1 metres long, a power dam of 331.8 metres long a spillway dam of 189.6 metres long and a solid right bank dam of 298.5 metres long. The dam is built so strong enough to withstand earthquakes of up to 8 on the Richter
