Two headrace spillway tunnels that will be constructed at the level of 1190 m, will be connected to CT-4 branches and they will have the capacity of spilling 1750 m3 of water per second each.
The exit point of the tunnel comprising of two branches will serve during the operation of the plant as well.
We have been informed that the tunnel’s entrance is located at the 1190 m point and its construction is accomplished. Its diameter is 15 m.
The Leader of the Nation, H.E. Mr. Emomali Rahmon visited the plant’s dam after he got acquainted with the construction process.
The Roghun HPP’s dam is raised to the point of 1065 m above the sea and 6 million cubic meter of construction material is laid in layers.
Now the reservour’s water reached 1058 m that makes it possible for operation of the first two units.
To present in total 200 million cubic meter of water stored in Roghun’s reservoir.
While getting familiar with the construction process, the Leader of the Nation, H.E. Mr. Emomali Rahmon moved through the transport tunnel of T-9. The T-9 transport tunnel is the facility that connects the plant’s tail with the dam crest and the site of vertical tunnels for operation of gates of turbine (pipe) waterspilling tunnels.
The transport tunnel of T-9 will also function during the operation of the plant. It stretches to the water delivery pipes and will serve the water delivery pipes’ gates from this point in the future.
Another section of the tunnel goes through the dam’s core and ensures movement pathway up to Shurob Plant. The length of T-9 transport tunnel is 530 m. The tunnel is located in the altitude of 1300 m above the sea.
Today, the President also got familiar with the works in the air tunnel.The air tunnel’s length to the core of vertical air tunnel is 487.5m and it is of 8 meters in diameter and of 8.4 meters in height. It will provide air to transformers hall and powerhouse and will serve to extract dust from this facility.
The tunnel is split into three sections with one section for extraction of dust, the second one for supply of fresh air and the third one for reaching the vertical tunnel and back to its exit point.
The air tunnel connects with the vertical air tunnel and currently drilling of a hole with 12.1 m in diameter is going on.
The First Unit’s Turbine Tunnel is another area, where the Leader of the State got familiar with the process of activities.
The vertical water intake tunnel of the first unit starts at the point of 1172 m and goes down to the point 956 m and its overall height is 216 m. Drilling activities has started with 8.7m of diameter and its final point diameter will be 7m, which will be fully covered with iron.
According to the received information the drilling activities in its pilot shothole with the diameter of 2.5 m are accomplished.
In the oversight area No 5a, the Leader of the Nation visited the accomplished and ongoing facilities, such as 500KW and 220KW Gas Insulated Switchgears, the plant’s dam site and other facilities.
The last facility the President visited during his visit was the deviation tunnel of ST-3.
Third floor construction tunnel (ST-3) was built with a view to transfer water from 1035 meters to 1145 meters.
The total length of the tunnel is 1858 meters. The tunnel’s capacity is 3500 cubic meters per second. The ST-3 tunnel has several auxiliary tunnels.
The exit of the ST-3 tunnel is located at 946-973 meters above sea level, with height of 26 meters and length of entrance – 100 meters.
It should be noted that the third drainage tunnel is one of the important facilities for ensuring the safety of the plant during the possible overloading with installation of repairing, emergency and main segment gates that was built for 2.8 billion Somoni.
Among other tunnels, it is the first tunnel that was built within the framework of construction the hydroelectric power station in the period of independence.
After familiarizing with the process of completed works in the construction area, the Head of State Mr. Emomali Rahmon highly appraised the quality of works and urged workers to timely and efficiently implement constructive measures at the “Rogun” hydroelectric power station.
After acquaintance with the work done at the site of the hydropower station, President Emomali Rahmon officially launched the second unit of the “Rogun” Hydropower Plant.
Thus, on September 9, 2019, another important and momentous event occurred in the history of sovereign Tajikistan and took a firm step towards achieving complete energy independence.
The ceremony was attended by the employees of the plant, activists, scientists, youth and veterans of the plant.
When the second unit was commissioned, the electricity generated was also transferred to the general power grid of the country.
It is timely to remind that, construction of the Rogun Dam was initiated on October 29, 2016 with the direct participation of the Head of State. On the same day, President Emomali Rahmon sat behind a bulldozer and closed the Vakhsh River with an hour and a half to commence the construction of the dam.
On November 16, 2018 the President of the Republic of Tajikistan Mr. Emomali Rahmon inaugurated the first unit of the “Rogun” hydroelectric power station and launched the activities of this great facility the century that will give impetus to the development and prosperity of the country.
The same day, the Leader of the Nation, His Excellency Mr. Emomali Rahmon, at the location of the construction of the Rogun Hydropower Plant, an important facilities of the plant – a high-voltage power transmission line of 500 kV “Dushanbe-Rogun” and closed separation device of Roghun HPP were commissioned with 19 electro-gas device 500 kV and 4 electro-gas device 220 kV.
Shortly after launching of the first unit of the Kohki Nur – ” Palace of light, ” the plant has generated and transmitted 570 million kWh of electricity to the country’s power grid.
The Rogun Hydropower Plant is the largest unit of the Vakhsh River Hydroelectric Power Plant with six aggregates, each with capacity of 600 megawatts. Rogun will be the largest hydropower plant in the region with a capacity of 3,600 megawatts (over 17 billion kWh). This number is one and a half times more than the production capacity of the Norak HPP.
Each visit of the Head of State to the Roghun HPP enhanced the spirit of the employees of this great Project and it was obvious that they were guided by the instructions and guidance of the President of the country H.E. Mr. Emomali Rahmon on stable and qualitative performance of their work.
