SAMPLE EXCERPT:

[. . .] 24th February 2010

Turbine 5 was made under installation

22 March 2010

Turbine 4 successfully unloaded

4th August 2010

Turbine 2 construction was finished

All the turbines in operation

2014

The cost estimated during the re-construction of the power plant was great and it was estimated that 10 billion rubles will be used in the restoration project in the year 2010 followed by 3.5 billion rubles for construction of the first phase of a shore spillway. The reconstruction of the building room will cost the power plant about 40 billion rubles. The total cost of 10 turbines alone that will take about 4 years for its construction and put into operation was estimated to be 37 billion rubles. The company has tried to get their reconstruction project financed by Russia's Sberbank with the facility of amount 20 billion rubles and had also negotiated a loan from European Bank for Reconstruction and Development. The operational efficiency and life of the plant was assessed as each unit was estimated to have the life of 40 years and operational efficiency of 96.6% thus bearing the risk of default only 3.4%. However, the engineering team has felt the construction of the power plant will be faced with the challenge of logistics management and timing that can prolong the operational setup of the plant beyond four years. The team is equipped with specialized and experienced engineers who will make the process in the shortest possible time and contingency plans were also set up but building additional spillway to control the spring floods and add reliability and safety.

Future Measures for Prevention and Risk mitigation

Hydroelectric plants are considered to be the safest mode of generating electricity. The technology have been adopted since centuries, its environmentally friendly as compared to other industrial production methods since minimum toxicities is being caused and less chemicals are involved in the process. The hydroelectric dam functions direct with water under high pressure to turbines. This led to the constructional design on the plant which requires lot of pipes, valves and regulatory mechanisms bearing great amount of water flowing with high speed and pressure. The water movement has inertia, when the water confined in a place is unable to find itself a room to flow it will make a pounding noise. The power plants have detectors for monitoring such noise and regulating the water level so that the turbine doesn't burst or results in any mechanical disturbance.

After analyzing the accident and operational design of the Sayano-Shushenskaya plant, it was observed that the plant didn't have correct form of regulatory and detecting mechanism to monitor and control the level of water flowing in the turbine from the dams or at the eleventh hour the detector and security mechanism installed din the plant ceased functioning. This has let the power plant learn a lesson to have security system and alarming mechanism as much of sound operation as the plant itself. The future lesson and operational approach for the power plant was to install the security system that can minimize the risk of non-communication to the maximum level leaving the company with critical factor of either 3.4% or even below that.

Before the installation of the power plant units the RusHydro has decided to test the Siberian Sayano-Shushenskaya Hydropower Plant spillway in September. The Sayano-Shushenskaya Hydropower Plant after the incident as the futuristic operational measurement has tried to make the spillway in additional facility with the capacity of 4,000 cubic meters per hour. This facility will be focused on providing security in time of spring floods. This step was taken by the company as their contingency measure and a lesson learned from the accident to resolve and prepare for every possible event of the future.

The hydroelectric plants generally didn't require lager number of workers as these industries is not labor intensive rather they are capital and technology intensive. Even small hydro-plants can function well on daily basis four years with fully automated system. Power plant like Sayano-Shushenskaya was labor intensive to that extend that the accident has caused 75 of its personnel die. The huge number of workers in the plant was possible due to the primitive Soviet Union policy on labor relations to promote employment in the country and concentrating their economic well-being on giving balancing attention to the profitability of the company, safety and security measure of the personnel itself. This has let the hydropower industry to realize the fact that these plants are risky places to work and their security measures to be adopted by the company should be of high standards. This will eventually result in either worker group to divert their attention from such type of employment and move towards safer option or let them work on the condition of high wages and high security prevention measures adopted by the management of the plant. On the other hand the strategic decision from the company perspective can be either to make the plant as much automated as possible and divert their investment on human capital from asset capital and make the security system to its optimum level that even machines didn't suffer massive looses.

The accident of the Sayano-Shushenskaya Hydro power plant was the combination of design flow, operation carelessness, lack of security measures and combination of all these parameters. It has made the industry learn that in the hydro power business it is very important for firms to have their system structured in the most professional level with all their parts operative throughout the operation. This requires continuous checkups and inspection from the engineering department and installation of electrical devices that can detect the dysfunctional component and alert the engineering team about it. Besides being environmental friendly, mitigation of risk in the business operation is important aspect of the company corporate social responsibility and policy of internal operations. The riskiness of the business operation can cause company to suffer financial loss due to decline in the profitability, reduction in the share prices and cost of re-building the plant (Naymushin, I August 2009). Besides these risks company also held responsible socially and ethically on the loss of human lives and the environmental damages incurred. Therefore, for maintaining sound operation and efficient functioning of the hydro power plant it is necessary for all the companies to have equipment of best quality installed, contingency plans made, operational activities to be monitored on regular basis, expert team of professionals to be hired and make the process as much automated as possible in operation and disaster management.
