The maximum level of filling of the Nurek HPP reservoir was reached at the end of August this year. At the end of August 2018, the water level in the reservoir of the Nurek HPP was 910.45 m, says the report “Monitoring and Earlier Alert in Tajikistan, prepared by the Ministry of Economic Development and Trade. This is the maximum level of occupancy of the Nurek reservoir: it has a normal retaining level of 910 meters.
The water level is 53.45 m above “dead mark” (857 m), upon reaching which the expedition of the reservoir is prohibited due to technical parameters. The average monthly inflow of the Vakhsh River in August this year amounted to 1382 cubic meters per second, which is 6.4% less than in the period last year. In September, the inflow of water usually decreases to 600 cubic meters per second, and in the first decade of October – to 400 cubic meters per second, after which the water resources accumulated in the reservoir begin to be used.
Meanwhile, earlier it was reported that there was no light in the Kulob region for several days: it was turned off by the hour – from 5 to 8 in the morning, and in the evening – from 17 to 24 hours. Experts from Barki Tojik said that this is not an energy limit, but only preventive measures related to preparation for winter.
In the local electric power networks of Kulob last week, “AP” was informed that it had received a verbal instruction from the management of “Barki Tojik” to turn off the power supply by the clock. This is allegedly due to the inflow of water in a small amount into the Nurek reservoir.
“The commissioning of the first unit of the Rogun HPP is expected soon, so some of the water remains in the Rogun reservoir, and the inflow of water into the Nurek reservoir has decreased,” Zarif Tabarov, deputy head of Shabakakhoi Barki Kulob LLC, told AP.
The information about the filling of the Rogun reservoir, which leads to a decrease in the inflow of water from the Vakhsh River, was confirmed on condition of anonymity by experts in the country’s energy structures. The first unit of the Rogun HPP is planned to be launched on November 16 this year. The rotor of unit No. 6, which will be the first to be commissioned, was assembled in its regular place at the beginning of July this year. The unit is expected to have a capacity of 100 MW at the initial stage after start-up.

The unit is expected to have a capacity of 100 MW at the initial stage after start-up. Its design capacity is 600 MW. Next, in April next year, it is planned to put into operation unit No. 5. In general, six hydroelectric units will be installed at the Rogun HPP, each with a design capacity of 600 MW. The total design capacity of the station is 3,600 MW, which makes it the largest hydropower plant in Central Asia.
