Tajikistan Shares 80% of Power Grid With Uzbekistan. Tashkent Just Cut It Off.

Uzbekistan severed electricity transmission to Tajikistan on April 15, cutting power to 2.1 million people in the Fergana Valley and escalating a water rights dispute that has simmered since the Soviet Union collapsed 35 years ago.

For Dilshod Rahimov, a 42-year-old textile factory supervisor in Khujand, Tajikistan's second-largest city, the blackout arrived without warning during the evening shift. Sixteen industrial looms stopped mid-weave. The factory's backup generator, designed for brief outages, ran out of diesel after eight hours. By morning, 340 workers had been sent home without pay.

The shutdown is the most severe infrastructure crisis between the two countries since independence in 1991, and it exposes the vulnerability of Central Asia's interlocking Soviet-era utility networks. Tajikistan depends on Uzbekistan for 80 percent of its electricity transmission during spring months when its own hydropower reservoirs are low. Uzbekistan, in turn, depends on Tajikistan's upstream dams to regulate water flow for cotton irrigation in the Fergana Valley, one of the world's most densely populated agricultural regions.

Tashkent has accused Dushanbe of withholding water from the Zarafshan River to fill the Rogun Dam, a massive hydroelectric project that has been under construction since 1976. Tajikistan denies the charge but has not released reservoir data since March. The water flow at Uzbekistan's Kattakurgan Reservoir, which supplies irrigation canals serving 1.8 million hectares of farmland, dropped 34 percent in the first two weeks of April, according to Uzbekistan's Ministry of Water Resources.

The Soviet Legacy: One Grid, Five Countries

Central Asia's electricity grid was designed in Moscow between 1967 and 1986 as a unified system spanning Kazakhstan, Kyrgyzstan, Tajikistan, Turkmenistan, and Uzbekistan. Power plants in Uzbekistan and Kazakhstan generated electricity; hydroelectric dams in Kyrgyzstan and Tajikistan stored water and regulated seasonal flow; pipelines from Turkmenistan supplied natural gas for thermal plants.

The system functioned because central planners in Moscow allocated resources according to a single five-year plan. After 1991, the infrastructure remained unified but the political authority fractured into five sovereign nations with competing economic interests. No binding treaty governs water allocation or energy pricing among them.

Tajikistan, the poorest of the five with a per capita GDP of $1,050, sees hydropower as its primary asset. The Rogun Dam, if completed, would be the world's tallest and generate 3,600 megawatts—enough to export electricity to Afghanistan, Pakistan, and potentially China. Uzbekistan, with 35 million people and an economy increasingly reliant on manufacturing, views upstream dams as an existential threat to its water security.

A Region on Edge

The power cutoff has paralyzed northern Tajikistan. Hospitals in Khujand and Istaravshan are operating on generator power, but fuel supplies are limited. The Tajik Aluminum Company, the country's largest industrial employer, shut down three of its five smelting lines on April 17 after electricity from the Nurek hydroelectric plant proved insufficient to maintain operations.

Tajikistan's Ministry of Energy announced rolling blackouts lasting up to 12 hours per day in residential areas. In Dushanbe, the capital, traffic lights went dark during evening rush hour on April 18, causing gridlock across the city. Mobile phone networks, dependent on grid power, intermittently failed in rural areas where diesel generators are scarce.

Uzbekistan's government has denied that the shutdown is political. Iskander Mullajonov, deputy director of Uzbekenergo, the state utility company, told reporters in Tashkent on April 17 that the grid disconnection was necessary for "emergency maintenance on the Syrdarya-Fergana transmission line." He did not explain why Tajikistan was not notified in advance or given an estimated restoration date.

Privately, three officials within Uzbekistan's Water Resources Ministry, speaking on condition of anonymity, confirmed that the cutoff was ordered by President Shavkat Mirziyoyev's office in direct response to reservoir data showing reduced river flow. One official said the decision was made "to send a signal that Tashkent will not tolerate unilateral water management."

The Rogun Factor

The Rogun Dam has been a flashpoint for decades. Construction began in 1976 under Soviet planning, stalled after independence, and resumed in 2016 with Chinese financing. The World Bank conducted an environmental impact assessment in 2014 that found the dam posed manageable risks to downstream countries if operated according to agreed protocols. No such agreement has been finalized.

Tajikistan insists the dam is purely for electricity generation and will not reduce downstream flow. Uzbekistan counters that even temporary water retention during the reservoir filling phase—scheduled to begin in late 2026—will devastate spring planting. The dam's reservoir capacity of 13.3 cubic kilometers represents roughly one-third of the Vakhsh River's annual flow.

The geopolitical stakes extend beyond bilateral tensions. China views Central Asia as a critical corridor for its Belt and Road Initiative and has invested heavily in energy infrastructure across the region. Russia, through its Unified Energy System framework, still maintains technical influence over grid operations in Kazakhstan and Kyrgyzstan. The United States, after decades of minimal engagement, launched a $50 million Central Asia Energy Security Initiative in 2024 aimed at diversifying the region's electricity grid.

Failed Treaties and Repeated Crises

This is not the first infrastructure standoff. In 2009, Uzbekistan cut natural gas supplies to Tajikistan during winter, leaving 60,000 households without heating. In 2012, Kyrgyzstan briefly shut down electricity exports to Kazakhstan over unpaid bills. In 2018, Tajikistan and Kyrgyzstan exchanged artillery fire near the Vorukh enclave, a dispute rooted partly in competing claims over irrigation canals.

Multiple efforts to establish a binding water-sharing treaty have failed. The Interstate Commission for Water Coordination, created in 1992, has no enforcement authority and serves primarily as a forum for grievances. A 1998 agreement on seasonal water and energy exchanges collapsed in 2009 when Uzbekistan stopped delivering natural gas to Tajikistan in winter months. A 2018 Framework Agreement on Water and Energy Cooperation, mediated by the European Union, remains unsigned by Uzbekistan.

The structural problem is asymmetry. Tajikistan controls the water but needs the grid; Uzbekistan controls the grid but needs the water. Both countries are authoritarian states with limited accountability, making compromise politically risky. And both face domestic pressures that make infrastructure disputes more volatile: Tajikistan's government derives legitimacy from promising economic development through energy exports, while Uzbekistan's agricultural sector employs 27 percent of its workforce and underpins rural stability.

External Powers and Competing Interests

China has positioned itself as the infrastructure financier of choice, but its investments have paradoxically deepened tensions. Beijing funded the Rogun Dam in Tajikistan and the Kambarata-1 Dam in Kyrgyzstan while simultaneously investing in Uzbekistan's textile manufacturing sector, which depends on stable water supply. China's strategy appears to be infrastructure provision without political mediation—a stance that locks in dependence but avoids the diplomatic cost of imposing solutions.

Russia, which maintained informal control over regional energy coordination through the early 2010s, has seen its influence wane. The Ukraine war redirected Moscow's diplomatic bandwidth, and Central Asian leaders have grown more willing to pursue independent foreign policies. Kazakhstan, historically the most pro-Russian of the five, declined Moscow's request to send peacekeeping forces to the Fergana Valley during a 2022 border clash.

The United States and European Union have offered technical assistance but lack the financial leverage to compete with China. The EU's Water, Energy, and Environment Programme for Central Asia, launched in 2022 with a budget of €34 million, focuses on capacity building and institutional reform—necessary but insufficient to resolve immediate crises.

What Comes Next

Neither government has indicated how long the electricity cutoff will last. Uzbekistan's Ministry of Energy stated on April 19 that "technical work" on the transmission line would continue "for the duration necessary," a formulation that leaves the timeline deliberately vague. Tajikistan's president, Emomali Rahmon, convened an emergency session of the National Security Council on April 18 but issued no public statement afterward.

Regional analysts note that planting season for Uzbekistan's cotton crop begins in early May, creating a deadline for both sides. If reservoir levels do not improve and irrigation canals remain undersupplied, Uzbekistan faces crop failure across millions of hectares. If Tajikistan's industrial sector remains offline for more than three weeks, the economic damage will exceed $200 million, according to estimates by the Asian Development Bank.

Kazakhstan and Kyrgyzstan, both dependent on the same grid, have offered to mediate. A trilateral meeting was scheduled for April 22 in Almaty, but Uzbekistan withdrew on April 20, citing "unresolved technical questions." That leaves direct bilateral negotiation as the only path forward—a format that has failed repeatedly over the past three decades.

For the 2.1 million people in northern Tajikistan living without reliable electricity, the geopolitical explanations offer little comfort. Dilshod Rahimov, the factory supervisor in Khujand, said his employer has warned that if power is not restored by the end of April, layoffs will begin. "We built this factory with Chinese loans," he said. "Now we can't run it because Uzbekistan turned off the switch. Who benefits from this?"
