Tajikistan Prepares for Another Winter Power Shortfall

Tajikistan is preparing for another autumn and winter in which electricity demand may outstrip supply. Network losses have fallen, and investment in hydropower continues, but officials say the seasonal imbalance between generation and consumption will persist. Mahmadumar Asozoda, chairman of state-owned power company Barki Tojik, said the imbalance would persist through the colder months. Asked whether electricity rationing would return, he did not rule it out. Tajikistan generates almost all of its electricity from hydropower, leaving supply tied to seasonal river flows. Output rises during the warmer months, when the country can meet domestic demand and export surplus electricity. In winter, river flows decline as electricity use increases for heating, creating a recurring shortfall. To cover part of the winter shortfall, Tajikistan plans to import electricity from Uzbekistan again. The two countries use a seasonal exchange: Uzbekistan supplies power in autumn and winter, and Tajikistan returns an equivalent volume during summer. Tajikistan imported 306 million kilowatt-hours (kWh) last winter, down from 350 million kWh a year earlier. Asozoda said the countries expect to sign a new agreement before the next autumn-winter season. Imports can ease the shortage, but they do not remove Tajikistan's dependence on hydropower or the winter drop in output. The seasonal arrangement with Uzbekistan gives Tajikistan access to power when domestic generation is lowest. As previously reported by The Times of Central Asia, Kazakhstan has signed a 20-year agreement to buy electricity from Tajikistan. Deliveries are expected to depend on additional generating capacity at the Rogun Hydropower Plant. The Nurek Reservoir stood at 888.21 meters on July 13, but Energy and Water Resources Minister Daler Juma said Tajikistan was experiencing low water levels. The country has reduced electricity exports and is retaining more water in its reservoirs for winter. Losses in the electricity system fell during the first half of 2026. At Barki Tojik's generating facilities, losses were 0.32% of output, down 0.07 percentage points from a year earlier. Losses in high-voltage transmission networks fell to 2.96%, while distribution losses dropped from 17.93% to 12.42%. Barki Tojik generated 8.89 billion kWh during the period, 2.7 million kWh less than in the first half of 2025. Hydropower plants supplied 7.93 billion kWh, while thermal plants produced 964 million kWh. The utility also bought 2.7 billion kWh from independent producers in Tajikistan and abroad, with Sangtuda-1 supplying 1.48 billion kWh. Rogun and Sangtuda-2 supplied 667.2 million kWh and 474.2 million kWh, respectively. Demand continues to rise as Tajikistan's population grows and industrial production expands, President Emomali Rahmon said in December 2025. The World Bank expects Rogun to help meet domestic needs and reduce recurring winter cuts. Rahmon has said rationing should end in 2027, when the third generating unit is scheduled to enter service, although the World Bank projects full completion in 2033. For the coming winter, Tajikistan is conserving reservoir water and arranging imports from Uzbekistan, but Asozoda's comments leave open the possibility of renewed rationing.
