Tashkent has moved to cement its long‑term energy strategy with a Russian‑backed nuclear power plant slated for the Jizzakh region, a project that the government says will meet soaring electricity demand and free up billions of cubic metres of natural gas. Yet the venture also threatens to deepen a water crisis that already grips Uzbekistan and its neighbours, prompting analysts to question whether the trade‑off is sustainable.

The nuclear complex, which will be built under the supervision of the International Atomic Energy Agency, is part of a broader plan that includes a national centre for handling radioactive waste. Official statements estimate that the plant could generate roughly 15 percent of the country’s power needs and cut annual gas consumption by about 3.6 billion cubic metres. The total value of contracts linked to the programme, most of them with Russian firms, has been put at up to $24.7 billion, signalling a deepening technological and financial interdependence.

Central Asia’s power outlook provides the backdrop for Tashakov’s decision. Regional electricity demand is projected to rise by around 40 percent by 2030, translating into a requirement for at least 62.8 gigawatts of fresh capacity, according to a 2025 energy outlook from the Asian Development Bank. Analysts such as Elyor Usmanov argue that the nuclear plant is a structural response to a widening supply gap driven by industrial expansion, demographic growth and the diminishing flexibility of gas‑fired generators.

However, nuclear reactors are among the most water‑hungry forms of generation. The United Nations’ latest water‑stress assessment shows that Uzbekistan’s water demand already exceeds supply by 23 percent, with an overall stress index of 123 percent—meaning scarcity is a present reality rather than a future threat. The plant’s proposed site lies adjacent to the Aydar‑Arnasay lake system, including Lake Tuzkan, an area already identified as hydrologically sensitive. Water specialist Bulat Yessekin estimates that the facility could draw more than 70 million cubic metres of water each year, a volume comparable to the consumption of a midsize city.

The region’s water picture is bleak. Per‑capita availability has fallen from roughly 8,400 cubic metres in the 1990s to about 2,500 cubic metres today, and projections suggest a further decline to 1,700 cubic metres by 2030—a threshold commonly associated with chronic scarcity. Inefficiencies exacerbate the problem: outdated irrigation networks leak up to 40 percent of water, while agriculture accounts for roughly 80 percent of total withdrawals. Climate models warn that under high‑warming scenarios, up to 80 percent of the Central Asian glacier mass could vanish, further curtailing runoff that feeds the Amu Darya and Syr Darya rivers.

The intertwining of water and energy is not merely an environmental issue; it carries geopolitical weight. The Amu Darya basin, which supplies both Uzbekistan and Afghanistan, could see its flow reduced by 8 to 20 percent as a result of new infrastructure projects, including the nuclear plant and Afghanistan’s Qosh‑Tepa canal. Kabul has begun to assert a larger share of the river’s waters, framing its claim as a lawful entitlement under international water‑sharing norms. Afghan officials have stressed a willingness to cooperate, but the emerging competition underscores the fragile balance that underpins regional stability.

Beyond the immediate water draw, the nuclear programme introduces long‑term risk management obligations. Andrey Ozharovsky, a nuclear physicist involved in the public safety initiative Radioactive Waste Safety, notes that radioactive waste remains hazardous for decades, sometimes centuries, demanding continuous monitoring and robust institutional capacity. The creation of a national waste‑management centre, tasked with transport, processing and storage, reflects an acknowledgement of these enduring responsibilities.

Potential environmental and health impacts also loom. If radioactive material were to enter watercourses, it could infiltrate drinking supplies and food chains, creating prolonged exposure pathways. Studies in the United States have linked proximity to nuclear facilities with elevated cancer mortality, although the causal relationship remains debated. Nonetheless, the possibility of accidental releases—whether from equipment failure or external threats—means that the plant could become a strategic vulnerability in an already tense security environment.

Financially, large‑scale nuclear projects have a mixed track record. Global experience shows that cost overruns are common; one notable example saw a budget swell from $9.8 billion to $25 billion over the construction period. Delays and cancellations can leave host governments bearing hefty debt loads, while reliance on a single foreign partner for fuel supply, maintenance and eventual decommissioning can limit policy flexibility. Uzbekistan’s engagement with Russia therefore embeds a long‑term dependency that will need careful management if the country wishes to preserve strategic autonomy.

In sum, Uzbekistan’s pursuit of nuclear power addresses a genuine need for reliable, low‑carbon electricity and promises to free up valuable gas for other uses. Yet the initiative also adds a substantial water burden to a basin already stretched to its limits, and it creates a cascade of long‑term environmental, health and geopolitical considerations. As the plant moves from blueprint to construction, the challenge for Tashkent will be to align its energy ambitions with the region’s water realities, ensuring that the quest for energy security does not inadvertently fuel a deeper resource crisis.
